PITKIN COUNTY OWTS REPORT 1266 OWL CREEK ROAD PITKIN COUNTY, COLORADO October 2019 Prepared by 118 West Sixth Street, Suite 200 Glenwood Springs, CO 81601 970.945.1004 970.945.5948 fax Page 2 of 7 1.0 Introduction The subject site is 1266 Owl Creek Road, in Pitkin County, Colorado (Parcel #264334300002). The applicant is seeking a permit to build a replacement on-site wastewater treatment system (OWTS) for the existing single-family residence. SGM has been informed that the existing OWTS consists of a 500-gallon barrel which serves as a septic tank. The barrel discharges effluent to two cinder block seepage pits. The subject site is severely constrained by steep slopes, wetlands, and the central location of the existing domestic well. There does not appear to be a feasible location in which to build a trench or bed soil treatment area (STA). The proposed replacement OWTS will consist of two septic tanks, an advanced treatment system, and two replacement seepage pits. 2.0 Existing Site Conditions The legal description of the property is “A tract of land located in Lot 9, Section 34, Township 9 South, Range 85 West of the 6th Principal Meridian.” The site consists of 2.00 acres. Existing site improvements consist of an existing residence, new shed/workshop, and a driveway. Ground cover in undeveloped portions of the site generally consists of mature Aspen and Fir trees, with a variety of shrubs and other woody vegetation. Owl Creek Road borders the site to the west, and a wetland area occupies the eastern, lower portion of the parcel. The extents of the wetlands shown are based on a delineation performed by SGM in the fall of 2017. Undeveloped steep slopes occupy the northern and southern areas of the parcel. The existing residence is served by a domestic well, located on the south side of the house. There is currently no access to the well because a concrete parking slab has been built over it. SGM has reviewed the Pitkin County Environmental Health Department records for the residences on the adjoining parcels and determined that the proposed replacement OWTS will not encroach into the setbacks for the wells or OWTS on those parcels. Representatives of SGM met with Kurt Dahl on site in May of 2018 to review the site conditions. 3.0 Proposed Construction The subject site is in an area where an OWTS is required. The proposed replacement OWTS will consist of septic tanks, an advanced treatment system, and seepage pits. The applicant is seeking relief from the 100-foot wetlands setback and the 25-foot cut bank setback. There is no reasonable alternative area in which to build the replacement OWTS where the 100-foot wetlands setback can be met. The Pitkin County OWTS regulations allow for the wetlands setback to be reduced in these circumstances. Per 43.A.7.d, “If the existing OWTS does not meet the minimum setback requirements in Table 7-1, the repairs must be no closer to features than the existing facilities.” The wetlands are 56.4 feet from the existing seepage pits at the closest point. The proposed OWTS has been designed to maintain this 56.4-foot separation from the wetlands. Because high ground water is present throughout the site, the applicant is proposing to use an Advantex AX-20 advanced treatment system to improve the effluent quality to treatment level 3N (TL3N). The former road cut in the steep slope is one of the two areas available to build the seepage pits. The bluff in the south corner of the property was also examined as a possibility, and it was deemed infeasible due to the disturbance required on the steep slope and physical space limitations. Site features that will require setbacks include a well, wetlands, existing structures, the road cut in the steep slope, and property boundaries. The setback shown for the well is approximate. Although the exact well location is not known, the approximate location is conservative as the well is shown located under the portion of the slab closest to the proposed septic tank and seepage pit area. The Page 3 of 7 septic tanks and advanced treatment system are both located outside the 50-foot setback from the well, and the proposed seepage pits are located beyond the 100-foot setback from the well. All components of the OWTS treatment system are located outside the 10-foot setback from the parcel boundary, and the 56.4-foot setback from the wetland. The seepage pits will be located beyond the 20-foot setback to the existing residence. The septic tanks and advanced treatment system will be located beyond the 5-foot setback to the existing residence. The seepage pit elevations will be approximately 7,865 and 7,860 feet above sea level (NAVD 88). The site of the proposed OWTS seepage pits is an east facing slope and is located north of the existing residence. The elevation of the septic tanks will be approximately 7,852 feet above sea level (NAVD 88). The proposed septic tanks and advanced treatment system will be located just east of the residence and effluent will be pumped from the septic tanks to the Advantex system and will either cycle through the septic tanks again or discharge to the seepage pits. Each seepage pit will consist of a perforated precast concrete cylinder with manhole accesses and gravel fill. An automatic distributing valve will be located near the seepage pits so that effluent will be equally distributed between the two cylinders. The soils in this area are generally sandy loam. The current site is not located in the Owl Creek floodplain. The limits of the effective Owl Creek floodplain are indicated on FEMA FIRM Panel 08097C0201C. A FIRMette of the site is in the appendix. No cultural features were identified in the preliminary investigation. Wetland areas have been identified on the site plan as delineated by SGM. 4.0 Subsurface Conditions A gradation test was prepared by H-P Kumar. (Gradation testing, Existing Residence, 1266 Owl Creek Road, Pitkin County, Colorado, Job No. 18-7-305, dated May 22, 2018, revised June 18, 2018). A representative of SGM observed the excavation of the test pit. The test pit was excavated to a depth of 8 feet below existing grade to collect soil at the proposed seepage pit site. A second pit was not excavated due to the narrow width of the road cut in which the seepage pits will be built. The soil profile appeared to be relatively consistent in terms of the characteristics of the soil exposed. Per the gradation report more than 50% of the rock within the sample had a diameter greater than 20 mm, resulting in a soil classification of R-2 which is a limiting layer. However, there is no reasonable alternative area in which to build the replacement OWTS where the wetlands setback can be met, even when it is reduced to 56.4 feet as previously discussed in this report. The USDA soil classification for the interstitial soil was found to be a sandy loam, type 2A. 5.0 Recommendations An OWTS for the single-family residence with septic tanks, advanced treatment system, and seepage pits can be constructed at this site. Effluent will discharge by gravity to the two new 1,500-gallon septic tanks. Effluent will then be pumped out of the septic tanks through the advanced treatment system and to the seepage pits. Before entering the seepage pits, the effluent will flow through an automatic distributing valve to equally distribute the effluent to both cylinders. Sewer Pipe: Sewer pipes shall be 2-inch SCH40 PVC pipe with a minimum slope of 2%. Sewer pipe from the residence to the septic tanks will be 4-inch SCH40 PVC. Sewer pipe from the pump basin to the ADV and to the seepage pits shall be ¾-inch SCH40 PVC. Joints shall be solvent welded. Cleanouts are required 1) at the stubout from the building, 2) at spacing not to exceeding 100 feet, and 3) upslope of two or more bends closer than ten feet in the sewer pipe. Bends in the sewer pipe Page 4 of 7 shall not exceed 45 degrees. The pipe shall be properly bedded per the typical trench detail presented on the design drawings. Septic Tanks: Two new septic tanks will be required. The septic tanks will be two 1,500-gallon, one compartment HDPE septic tanks that will receive effluent directly from the single-family residence. The effluent will be pumped through an Advantex advanced treatment system. The tank lids shall conform to the current county OWTS regulations. The tanks shall be installed with insulated, watertight access risers with securable lids. The septic tank shall: 1) be located down gradient of the home, 2) be buried no deeper than four feet, and 3) be at a location accessible for siphoning and maintenance at the tank. The installer must coordinate with the general contractor as to the elevation of the stubout. A septic tank deeper than four feet will not be allowed. Concrete deadman anchors shall be provided and shall be installed per the septic tank manufacturer’s recommendations. The electrical control panels for the pump tanks shall be installed within line of site of the pump vault riser. Controls and alarms shall be UL listed. The panel shall be weatherproof to protect against adverse weather conditions. The control panels shall meet the Orenco-authorized service provider’s requirements to maintain the OWTS. Pumping Systems: The dosing pump shall be an Orenco Model PF2005 with a Biotube effluent screen having 1/8-inch screen openings. The pump system shall have 3 floats: 1) High Water Alarm Float, 2) Pump ON Float and 3) Pump OFF Float. The dosing volume to the seepage pit shall be as noted on the design drawings. The effluent filter handle and float tree handle in the second tank shall extend to within six to twelve inches of the lid. The pump for the Advantex system shall be as noted on the drawings. Advanced Treatment System: Two Orenco Advantex AX20 advanced treatment filter units shall be installed. The AX20 shall be positioned as shown on design drawings. The AX20 shall be installed and configured in Mode 3B by an Orenco authorized service provider. The lid and riser covers for the AX20 shall have a minimum of 1-inch of rigid insulation per regulatory requirements. Timer setting and effluent dosing shall be per Orenco’s recommendations and shall be set by an Orenco authorized service provider. An Orenco-authorized service provider shall be contacted to provide regular maintenance per Orenco’s recommendation. Automatic Distribution Valve (ADV): The ADV shall be an Orenco Model V4402 assembly that will alternate distribution of effluent between both seepage pit cylinders. The ADV shall be installed in a PVC riser, with an insulated fiberglass locking lid, that is large enough to allow for maintenance personnel to access the valve assembly and disconnect all unions to allow for removal, repair, or replacement. The ADV shall be located with the discharge pipe at a point that will allow the valve to drain both to the seepage pits and back to the pump basin between dosing cycles. Seepage Pits: The seepage pits shall be installed as indicated on the design drawings. The seepage pits will have a 5 feet diameter with gravel surrounding the perforated concrete cylinder. The over- excavated volume of the pit will be filled with ½ to 2-½ inch washed gravel per the specification in design drawing details. Two ¾-inch diameter SCH40 PVC pipes will be used to convey effluent from the automatic distributing valve to the two seepage pits. Prior to installation of the OWTS, SGM recommends further slope/global stability evaluation by a geotechnical professional of the steep slope around the seepage pits, with consideration of the effects Page 5 of 7 of the effluent discharge to the soil and recommendations as appropriate. All recommendations by the geotechnical professional shall be strictly adhered to. The surface of the seepage pits shall be seeded after installation of the system. A native, upland seed mix approved by Pitkin County shall be used. These mixes do not require irrigation and develop a growth of 10 to 15 inches high. No automatic sprinkler system shall be installed over the seepage pit. Vehicular traffic and livestock shall be kept off the seepage pits. No landscaping, impervious surfaces or plastic sheeting can be installed over the seepage pits. 6.0 Installation Observations The installation of the OWTS shall be observed by Pitkin County and the civil engineer as noted on the plans. Observations of all of the OWTS component installations are required. A final dosing observation will be required prior to placing the OWTS into service, and the installer shall fill the septic tanks with water so that the dosing observation can be conducted. SGM’s office shall be called at 970-945-1004 to observe the installations at least three days in advance. The installer is responsible for scheduling inspections by Pitkin County. 7.0 Operation and Preventative Maintenance Schedule The goal of an operation and maintenance schedule is to observe the operation, and perform minor maintenance to the onsite wastewater system to allow for proper, long-term functioning of the system. Septic tanks: The scum and sludge accumulation in the septic tanks shall be monitored yearly. Once the cumulative scum or sludge thickness reaches 25% of the tank depth, the entire tank shall be pumped. A pumping frequency of 1 to 3 years is expected at design flows. An alternative is a regular pumping frequency of every 2 years. Filter and Effluent Pumping System: The effluent filter at the septic tank discharge shall be cleaned (hosed off) at the time of pumping or as needed. The effluent pumps shall be checked semi-annually to ensure pumps are functioning properly. If the alarm sounds, the pumps and floats shall be checked and/or serviced immediately. Advanced Treatment System: A copy of the Advantex O&M Manual is included with this letter. An Orenco-authorized service provider shall be contracted to provide regular maintenance per Orenco’s recommendations. General: System users must realize that an on-site wastewater treatment system is different from public sewer service. There are daily considerations such as not putting plastic or other non- biodegradable material into the system. Water use shall be monitored so that toilets are not allowed to leak when seals malfunction. Allowing fixtures to flow continuously to prevent water lines from freezing is not acceptable. Although the proposed system can accommodate variable flows, spreading water use over several hours and eliminating peak flows is recommended. To illustrate the point, a malfunctioning toilet can discharge in excess of 1,000 GPD. Excessive daily loading could flood and irreparably harm the OWTS. SGM recommends against the installation of a water softener. The chemical and hydraulic loading from the backwash of a water softener would be damaging to the OWTS and a separate drywell shall be constructed for the backwash waste, if a softener is installed. No landscaping or plastic can be used over the seepage pits, which would reduce the performance of the seepage pits. The design of the OWTS is based on the treatment of domestic sewage only. Swimming pool or spa water is not to Page 6 of 7 be discharged into the OWTS. The proposed OWTS design is based on the regulatory flows noted in the attached calculations. Increased flows may hydraulically or organically overload the OWTS, causing premature failure. 8.0 Limitations Our investigation, layout, design, and recommendations are based on data and other information provided by others. The contents of this letter shall not serve as the basis for any third party engineering design. If conditions that are considerably different from those described in this report or indicated on the construction documents are encountered, SGM shall be called to evaluate the conditions. If the proposed construction is changed, SGM shall be notified to evaluate the effect of the changes on the OWTS. All construction shall be in accordance with the Pitkin County OWTS regulations. Pipe type and size, burial requirements, septic tank construction, and other specifications, which are not depicted in our report, shall conform to the requirements of the Pitkin County OWTS regulations. The installer of the system shall be licensed by the Pitkin County Environmental Health Department and shall have demonstrated knowledge of the Pitkin County OWTS regulations and requirements.

Pump curves show the relationship between flow and pressure (total dynamic head, or TDH), providing a graphical representation of a pump’s optimal performance range. Pumps perform best at their nominal flow rate. These graphs show optimal pump operation ranges with a solid line and show flow rates outside of these ranges with a dashed line. For the most accurate pump specification, use Orenco’s PumpSelect™ software.

Must be backfilled and installed in accordance with Infiltrator Water Technologies, Infiltrator IM-Series Septic Tank General Installation Instructions and for shallow ground water conditions reference the Infiltrator IM-Series Tank Buoyancy Control Guidance. Please visit www.infiltratorwater.com/images/ pdf/ManualsGuides/TANK01.pdf for the latest information. BEFORE YOU BEGINInfiltrator Water Technologies’ tanks must be installed according to state and/or local regulations and approvals, which supersede the manufacturer’s installation instructions. If unsure of the installation requirements for a specific site, contact the health department or permitting authority. The IM-Series referred to in this document includes the IM-540, IM-1060, and IM-1530 models. WARNING: IMPLOSIONS MAY CAUSE SERIOUS INJURY Follow Infiltrator Water Technologies vacuum test instructions INSTALLATION SITE SELECTION 1. Do not install the tank in vehicular traffic areas. The tank is designed for non-traffic applications. 2. The allowable soil cover depth is 6 to 48* inches (150 to 1,200 mm). *18-inch (450 mm) max. in Florida for Cat. 3 IM-Series tanks; 48-inch (1,200 mm) max. in Florida for Cat. 4 IM-Series tanks; 36-inch (900 mm) max. in Massachusetts, New Hampshire, North Carolina, and Oregon. 3. Do not install where uninterrupted saturated soil could be present from the tank bottom to a height exceeding that of the outlet pipe saddle. See page 4 illustration. EXCAVATING AND PREPARING THE SITE 1. Unless buoyancy control measures are required, the excavation width and length should be 18 to 36 inches (450 to 900 mm) larger than the tank on each side or sized as necessary to ensure proper backfill compaction, as outlined in Steps 5-10 of “Backfilling the Tank” in this document. See Infiltrator IM-Series Tank Buoyancy Control Guidance document, available online at www.infiltratorwater.com, for specific excavation requirements when installing buoyancy control measures. 2. Excavation depth shall account for the 55-inch (1,375 mm) tank height. Also account for 4 inches (100 mm) of bedding (if required) and cover depth (permissible cover depth is 0.5 to 4 feet (150 to 1,200 mm) of soil). Note: If uninterrupted saturated soil conditions exist from the tank bottom to a height exceeding that of the outlet pipe saddle, tank structural integrity may be compromised. See page 4 illustration. Indiana installations: If the depth of the uninterrupted saturated soil conditions cannot be determined from the site soil evaluation report or other site-related data and other information indicates the possible presence of a perched ground water table, tank installation is permissible. 3. Inspect bottom of excavation to verify suitability of native soil for tank installation. Soils with large, protruding, or sharp stones or other similar objects that may damage the tank are not suitable. 4. The tank may be installed either in suitable native soil (see Backfilling the Tank section) or a minimum 4-inch (100 mm) layer of well-graded granular soil having particles less than 3 inches (75 mm) in diameter, or maximum 0.5-inch (13 mm) diameter crushed stone. 5. Create a uniform, compacted, level surface to ensure that the bottom of the tank is evenly supported. Verify that the installation surface is flat. INSTALLING THE TANK 1. Inspect the tank for damage before installation. 2. If the tank inlet and outlet penetrations are not drilled, drill holes using the drill points provided at each of the inlet and outlet ports according to the applicable Inlet and Outlet Hole Locations section of this document. The inlet and outlet may be drilled on either the sides or ends of the tank, as required based on applicable codes and site conditions.* * Indiana, Kentucky, Oregon, West Virginia, and certain Florida and Texas tanks are factory-drilled. 3. The gaskets supplied with the tank are compatible with Schedule 40 and SDR 35 pipe using a 5-inch-diameter (125 mm) hole saw. 4. Install the rubber gaskets at the inlet and outlet. 5. Using all four of the tank’s integral lifting lugs, lower tank into excavation. 6. Slide the inlet and outlet pipes* through the gaskets. Soapy lubricant may be used to slide the pipe in. *For North Carolina, the inlet pipe shall be a straight pipe with no tee. 7. Horizontally position the tee 1½ inches (40 mm) from the access port rim, allowing the tee to fit into the recess in the access port lid (see detail). 8. Install lids and risers (see Installing Risers section) as necessary. Rotate lid over access opening until it indexes to tank and drops into position. BACKFILLING THE TANK Note: Infiltrator tanks do not require filling with water prior to backfill placement. Water filling and backfilling to the tank mid-height is required if the tank is left in either an open or backfilled excavation that may fill with water from rain or other sources. 1. Backfill with suitable native soil (max. 3-inch (75-mm) stone diameter). If native soil is unsuitable, replace unsuitable fraction with suitable soil. If suitable soil is not locally available, contact Infiltrator for assistance. 2. Suitable soil shall include soil textural classes defined in the United States Department of Agriculture soil triangle. a) For a tank soil cover depth of 0.5 to 2.0 feet (150 to 600 mm), suitable soil textures include: Infiltrator IM-Series Septic Tank General Installation Instructions MAY 2019 Failure to comply with these installation instructions will invalidate the warranty.

Compatible risers include 24-inch (600 mm) diameter products such as the Infiltrator TW-Riser, EZset by Infiltrator, PolyLok®, Inc., and Tuf-Tite® Corporation, in addition to 24-inch (600 mm) diameter corrugated HDPE and IPEX Ultra Rib® PVC pipe. Follow Infiltrator’s IM-Series Tank Riser Connection Guidance. 2. In Oregon only, watertightness testing shall include filling with water at least 2 inches above riser connection, with no more than 1 gallon leakage per 24 hours, per OAR 340-073-0025(3). INSTALLING PUMPS AND RELATED EQUIPMENT Pumps may be supported on a stable, level 16x16-inch (400x400-mm) platform positioned on the bottom of the tank. One 16x16-inch block or two 8x16-inch (200 -mm x 400-mm) side-by-side blocks may be used. Limit block height to account for pump height and liquid levels during pump cycles. Block(s) should be placed below an access opening and level upon the tank bottom. For two blocks, orient them perpendicular to ribs on the tank bottom, if present, for stability. Installation of products such as electrical conduit and wiring, pumps, water level control equipment, valves, siphon equipment, etc. shall be in accordance with the product manufacturer’s instructions and compliant with applicable state or local rules and regulations. Appurtenances shall be fastened to the tank riser system and not the tank body or access opening rim. Where possible, appurtenances shall be installed to facilitate maintenance and repair access via the tank access openings. Note: Prefabricated pump vaults may be installed. GENERAL SPECIFICATIONS • Failure to comply with installation instructions will void warranty. • Prior to ground disturbance, check for subsurface obstructions and utilities in conformance with applicable requirements. • Operating water temperature shall be less than 100° F (40° C). • In cold conditions, handle and backfill tank with care to prevent impact damage. • Tanks are not fire resistant. Store away from ignition sources. • Removal of structural bulkheads is prohibited; removal of locking clips on the IM-Series tank mid-seam connection is also prohibited. • Only suitable for potable applications if the tank bears the NSF/ANSI 61 certification mark. Otherwise, tank is recommended for use in septic, rainwater/stormwater storage, holding, and pump applications, or other non-potable uses. • Infiltrator tanks shall not be installed above ground. Contact Infiltrator if the 6-inch (150-mm) minimum soil cover depth cannot be met. b) For a tank soil cover depth that is greater than 2.0 feet and up to 4.0 feet (600 to 1,200 mm), suitable soil textures include: 3. Backfill should not have stones greater than 3 inches (75 mm) in diameter or excessive clods that do not break apart during placement and compaction. Backfill must be capable of occupying the spaces between the tank ribs and beneath the haunches. Note: Rounded screened aggregate (e.g., pea gravel) is not a suitable backfill. 4. Standard field soil classification methods shall be used to determine the soil textural class. Note: Under most circumstances, the determination of soil dilatancy will not be required. Dilatancy shall be determined in the field using a test that does not require specialized equipment, per ASTM D2488, Section 14.3. 5. Place and compact soil by walking-in beneath the haunches of the tank. 6. Place backfill around the four sidewalls in an alternating manner, so that the backfill height along the four sidewalls is maintained within a 12-inch (300-mm) tolerance. 7. Do not backfill top of tank before sidewalls are completely backfilled. 8. Continue to place backfill along the sidewalls in 12-inch (300-mm) lifts. Place backfill between the ribs on the sidewalls such that the space between the ribs is completely filled with soil. 9. Compact backfill material either by walking-in, hand tamping or mechanical compaction (includes backhoe bucket). If mechanical compaction is used, such as a walk-behind tamper or backhoe bucket, a single pass is recommended. Compact each lift prior to placement of next lift. Compact backfill from tank walls to excavation sidewalls. 10. Complete backfilling and grade the area. 11. A minimum 6-inch (150-mm) depth of suitable soil must be placed over the top of the tank. The balance of backfill placed to finish grade above the tank may be either suitable or unsuitable soil. 12. Establish a strong stand of erosion-resistant vegetation. Grade to prevent the backfilled excavation from filling with surface runoff. If uninterrupted saturated soil conditions are present from the tank bottom to a height exceeding that of the outlet pipe saddle, tank structural integrity may be compromised. SHORT AND LONG-TERM GROUNDWATER CONTROL It may be necessary to implement groundwater control measures during tank installation. Maintain dry conditions by expanding the excavation to create a short- term groundwater collection sump for temporary placement of a dewatering pump if needed. Long-term groundwater control measures such as underdrains and interceptor trenches may be sensible if the site is amenable to construction of a control system and such systems are not prohibited by regulation or law, and the tank location is not subject to flooding. Properly installed underdrains and groundwater interceptor trenches may prevent the need for tank buoyancy control measures. INSTALLING UNDER SHALLOW GROUNDWATER CONDITIONS Buoyancy control measures may be required if the Infiltrator tank is to be installed with less than 12 inches (300 mm) of soil backfill cover, and where uninterrupted saturated soil conditions have the potential to rise 30 inches (750 mm) or more above the tank bottom. Otherwise, no control measures are required (see Table 1). The need for buoyancy control measures must be determined based on backfill cover depth and height of uninterrupted saturated soil conditions above the tank bottom according to Table 1. Refer to Infiltrator IM-Series Tank Buoyancy Control Guidance document for more information. Failure to comply with these installation instructions will invalidate the warranty.

Tank buoyancy control measures must be implemented according to state and/or local regulations and approvals, which may supersede these guidelines. If unsure of the requirements for a particular site, contact the local health department or permitting authority. If tank buoyancy control measures are implemented, refer to Infiltrator IM-Series Tank Installation Instructions and Riser Connection Guidance documents, as applicable, for completing the installation. How to Use this Document 1. Using Step 1, Table 1, and Figures 1 and 2, verify that the level of uninterrupted saturated soil is below the height of the outlet pipe saddle and determine if buoyancy control is required. 2. Use the appropriate row in Step 2, Table 2 to determine the minimum buoyancy control methods for the site conditions. 3. Once the preferred buoyancy control method is selected, follow the implementation procedures provided in Step 3. Step 1 – Determine Need for Buoyancy Control Required information: (1) maximum height of uninterrupted saturated soil above the tank bottom; and (2) the depth of soil cover above the tank top. Tank buoyancy control may be required if: • the level of uninterrupted saturated soil outside the tank has the potential to rise 30 inches (750 mm) or more above the bottom of the tank; and • less than 12 inches (300 mm) of soil cover is to be placed as backfill over the tank top. Table 1 Instructions 1. In the left-hand column of Table 1, locate the row corresponding to the height of the uninterrupted saturated soil elevation outside the tank and above the tank bottom (Parameter I) for the site conditions. See Figure 2. 2. Follow that row to the right until reaching the column corresponding to the depth of soil cover above the tank top (Parameter II). See Figure 2. 3. If the tank model is listed in that cell, then buoyancy control is required (proceed to Step 2). If the tank model is not listed in that cell, then no buoyancy control is required. 4. IM-Series tanks shall not be installed where the uninterrupted saturated soil level outside the tank exceeds the height of the outlet pipe saddle. NO BUOYANCY CONTROL IS REQUIRED IF THERE ARE AT LEAST 12 INCHES (300 MM) OF SOIL COVER ABOVE THE TANK TOP.

See Supplemental Downward Force discussion below. 2. IM-Series outlet pipe saddle height is 43 inches (1,075 mm) above tank bottom (see Figure 1). Step 2 – Determine Buoyancy Control Method Step 2 is used if the Step 1 analysis shows that buoyancy control is required for the tank model and installation conditions. The site-specific maximum height of uninterrupted saturated soil outside of the tank and above the tank bottom and the depth of soil cover above the tank top must be known to complete Step 2. Table 2 Instructions For the appropriate tank model, select the desired buoyancy control method under each method description column. Refer to Step 3 – Implementation and Compatible Devices and Products sections of this document for additional information on the buoyancy control methods shown in Table 2. Supplemental Downward Force The minimum supplemental downward force required is included in Table 2 to allow custom buoyancy control methods. These values include a factor of safety of 1.5 applied to the calculated downward force required to restrain the tank. Custom-designed buoyancy control methods shall conservatively consider saturated soil conditions from the bottom-of-tank elevation to ground surface. As long as buoyancy control is provided that supplies the minimum downward force listed in the table (for poured-concrete blocks or other methods designed by third parties), the tanks are calculated to be stable for the uninterrupted saturated soil level outside the tank and above the tank bottom and corresponding soil cover conditions. All Infiltrator strapping and fastening recommendations apply for custom-designed buoyancy control methods. Contact Infiltrator’s Technical Services Department with any questions regarding supplemental downward force requirements. Step 3 – Implementation Effective buoyancy control of Infiltrator tanks requires careful preparation, thorough excavation, precise placement, secure strapping and proper backfilling, as described and illustrated below. Excavation Requirements It is recommended that the excavation width provide a minimum of 36 inches (900 mm) clearance beyond the tank on all sides when utilizing buoyancy control. This will allow sufficient space within the excavation to place anchoring equipment and fasten strapping. The excavation should provide a minimum 48-inch (1,200 mm) clearance beyond the tank when using Chance™ No-Wrench Screw Anchors to allow for room to properly install the screw anchors. The actual excavation size shall be determined by the installer. Refer to Infiltrator IM-Series Tank Installation Instructions for additional excavation procedures. Concrete-filled Half Pipe Construction Concrete-filled half pipe shall be supported with soil or other stabilizing means below the pipe haunches prior to concrete placement. The stabilization shall prevent the pipe from rolling during placement and curing of the concrete. Concrete shall be allowed to cure for a minimum of one day prior to tank backfilling. Placement of Deadmen and Anchors Concrete deadman anchors are to be installed at the bottom of the tank excavation, parallel to the long axis of the tank (see Figure 3). Figure 3: Plan View The deadmen should be placed close to, but not touching, the tank on both sides of the tank to allow the placement of backfill between the deadman anchor and tank sidewall (see Figure 4). Figure 4: Section View PROVIDE ADEQUATE SPACE FORBACKFILL PLACEMENT BETWEENDEADMAN ANCHOR AND TANK STRAPPING (TYPICAL) DEADMAN ANCHOR STRAPPING DEADMAN ANCHOR (TYPICAL) STRAPWIDTH 6" MIN EXTENSION 6" MIN EXTENSION Step 3 – Implementation continued Helical anchors should be installed so that the eye loop is level with the bottom of the tank excavation. They must be in line with the tank model strapping locations (see Figure 5) or lifting lugs, as appropriate. Anchors must also be installed at such a distance from and angle to the tank so that the strapping is within 5° of alignment with the anchor shaft per the anchor manufacturer’s recommendations. Figure 5: Strap Positioning Concrete Collar Backfill the tank to the mid-seam area. Concrete (minimum 3,000 psi at 28 days and minimum 6% air entrainment) shall be cast in contact with the exterior surface of the tank to allow interlock with sidewall ribs and the mid-height flange. The bottom of the concrete collar shall be cast at the top of the mid-seam flange. Strapping Proper installation of straps over the tank is critical for tank stability under changing conditions both inside and outside the tank. Straps must be placed at the specified strapping locations for each model, as illustrated in Figure 5. Strapping locations are embossed on the exterior surface of the tank with the following text: “SHIPPING/ANTI-BUOYANCY STRAP HERE.” The IM-Series tank strapping locations correspond to structurally reinforced areas of the tank body. Straps must never be placed over access openings, lids, or inlet/outlet piping. (Straps must be tightened with a ratchet or turnbuckle system to remove slack and slightly pre-load the system). Strapping Notes: 1. The buoyancy control shall be centered across the straps (excludes helical anchors). The control shall extend a minimum of 6 inches (150 mm) beyond the maximum strap width (see Figures 3 and 5). 2. The minimum deadman length corresponds to the tank model-specific strap width plus 12 inches (300 mm). Backfill and Cover Place backfill between deadman anchor and tank sidewall to fully fill void and tank body corrugations. A minimum 6” layer (150 mm) of suitable cover material is required over all Infiltrator tank installations. Mound cover to direct surface water drainage away from the tank excavation footprint to prevent filling of the tank excavation with precipitation. Establish erosion- resistant vegetation within the tank installation footprint. Refer to Infiltrator IM-Series Tank Installation Instructions for complete backfilling and cover procedures. Parts and Supplies The parts and supplies necessary are to be purchased separately from the tank. All parts and supplies are either commercially available or available through Infiltrator’s network of tank distributors. Some parts may require fabrication on site using common construction practices. General SpecificationsCompatible Devices and Products Infiltrator tanks are compatible with the following products for buoyancy control: • Tie-down straps: high-tensile-strength, 10,000 lb (4,500 kg) minimum capacity, nylon or polyester, with corrosion-resistant hardware. • Concrete deadmen anchors: concrete-filled plastic half pipe, precast parking bumper, precast traffic barrier, or precast block. • Helical anchors: Chance™ No-Wrench Screw Anchors with minimum 6-inch (150 mm) diameter, Class 7 or equal. • Mid-Seam Concrete Collar: cast-in-place concrete (minimum 3,000 psi compressive strength at 28 days and minimum 6% air entrainment). Tie-Down Straps Straps are commercially available in varying lengths and with assorted hardware and tightening options. Nylon or polyester strapping with minimum 8,000 lb (3,650 kg) capacity is required for buoyancy control use with Infiltrator tanks. Place straps over the tank at specified locations only (see Figure 5). (Tighten straps snugly with a ratchet or turnbuckle system to remove all slack and slightly pre- load the system). All connections, fittings, and hardware must be corrosion resistant or coated with epoxy or other corrosion-resistant materials to inhibit deterioration in the subsurface environment. Consider encapsulating such components in heat-shrink tubing or applying a corrosion-resistant coating prior to burial. Concrete Deadmen Anchors Recommended concrete deadmen anchors include filled plastic half pipe, precast parking bumpers and traffic barriers, and precast blocks. The weight of the deadmen anchors combined with the weight of soil above them provides buoyancy control when properly secured. Deadmen anchors are placed at the bottom of the tank excavation on opposite sides of the tank. The deadmen anchors are fastened to each other with tie-down straps placed over the tank at the locations specified for each tank model (see Figure 5). Concrete-filled Plastic Half Pipe Use Schedule 40 PVC plastic pipe with a minimum inside diameter of 15 inches (375 mm) or HDPE corrugated pipe with a minimum inside diameter of 18 inches (450 mm) cut in half lengthwise. Fill with concrete having a minimum unit weight of 145 lbs/ft3 (2.32 metric tons/m3) reinforced with three equally spaced 40-grade, 1/2-inch (13 mm) diameter steel bars.

Review and approval for the design of any OWTS proposing to use this technology will be reviewed by the local public health agency. As individual local public health agency regulations may be more stringent than Regulation 43, the Division cannot ensure the acceptance of a treatment technology within any given jurisdiction. Any modifications to the physical attributes or characteristics of this treatment technology must be submitted to this office for review and acceptance by the Division prior to sale in Colorado. The Division will review modifications, any additional third party verification reports and issue a revised acceptance letter, or denial, as appropriate. Joe Soulia, Orenco Systems Inc. March 26, 2015 On-site Wastewater Treatment System Treatment Technology Acceptance Page 2 of 4 Table 1. Design Criteria for Orenco Systems Inc., Advantex series models listed above: Design Criteria 1. A septic tank consistent with section 43.9(A) and 43.9(B) and an effluent screen consistent with section 43.3(44) and 43.9(I) must precede the treatment unit. Surge volume may be required for some applications based on manufacturer recommendations. Pretreatment for non-residential kitchens must include adequate separate grease separator tank(s) prior to the primary septic tank(s) as required in section 43.9(J) of Regulation 43. 2. Mode configuration requirements: a. In order to attain TL2, TL2N or TL3 effluent, the design of the treatment system may be configured in “Mode-1” or “Mode-3”. This will ensure the required BOD, TSS and TN reductions. Mode 1 is defined as recirculating all of the filtrate to the secondary chamber of the processing tank. b. The design of the treatment system for TL3N must be configured in “Mode-3” in order to obtain the required nitrogen reduction for this treatment level. Mode 3 is defined as recirculating all, or a portion, of the filtrate to the primary chamber of the processing tank. 3. Cold weather considerations, general: a. All units must incorporate 1-inch insulation attached to the bottom of all lids and risers covers integral to the treatment unit. Insulating around the process tanks, risers, and other components will be at the discretion of the design engineer. b. For installations in areas where snow accumulates each winter, the air vent must be extended to ensure it terminates above the peak snow level. 4. Cold weather considerations for TL2N, TL3 and TL3N: a. As per data supplied by Orenco Systems Inc., treatment systems that integrate “passive” ventilation do not require a warm air source for the treatment pod. This configuration would be typical of a single family residential treatment system. b. Systems that integrate “active” air ventilation will require a temperature controlled air source to ensure that the temperature of the filtrate remains above 50º F. This configuration would be typical of a commercial treatment system with an AX-100 treatment unit. 5. Timer settings for dosing the treatment unit: a. Timed-dosing to the treatment unit is required. The initial timer settings should be established based on the expected average daily flow and a 4:1 filter recirculation ratio. b. A residual pressure of 3 to 6 feet (5 feet desired) within the treatment unit is used to determine the initial timed-dose settings. c. AX-20 and AX-20RT: The “on” time should remain constant at 45 seconds per dose. The “off” time should be adjusted depending on the average daily flows. See the Orenco Systems design manual for further specifications. d. AX-25RT: The “on” time should remain constant at 60 seconds per dose. The “off” time should be adjusted depending on the average daily flows. See the Orenco Systems design manual for further specifications. 6. Design flow shall be for maximum occupancy. Design flow for single-family residential designs may vary based on the regulations adopted by the local board of health for each specific location. Design flow values and strengths for multi-family and commercial systems shall be consistent with section 43.6(A)(4). Therefore, all design criteria in this acceptance are based on total gallons per day and the assumption of residential strength wastewater. Joe Soulia, Orenco Systems Inc. March 26, 2015 On-site Wastewater Treatment System Treatment Technology Acceptance Page 3 of 4 7. The design must include pressure dosed distribution of effluent. Reductions in soil treatment area size or separation distances shall be as described in section 43.10(C)(4) of Regulation 43. 8. The designated higher level treatment rating is identified for each model on page 1. Use in higher level treatment applications requires system be designed by a Colorado Licensed Professional Engineer. The accepted treatment product may also be used for applications requiring less than the approved treatment level of the product. Reductions in soil treatment area size or separation distances based on higher level treatment may not be applied unless the local public health agency has a maintenance oversight program in place as described in section 43.14.D of Regulation 43. In locations where the local public health agency has not adopted a maintenance oversight program, the treatment system may be used but only with soil treatment area size and separation distances consistent with treatment level TL1 requirements. 9. In addition to these design criteria, other provisions of Regulation 43 and local regulations also apply to a specific design as well as good OWTS design practice. The Division does not approve manufacturer design manuals. Manufacturer provisions shall not be applicable if those provisions are not consistent with Regulation 43, these design criteria, and the regulations adopted by the local board of health for the design location. Local public health agencies will review proposed designs to confirm consistency with Regulation 43, these design criteria, the local board of health regulations adopted pursuant to Regulation 43, and good OWTS design practice. 10. Monitoring of the system may be required by the regulations adopted by the local board of health for the design location. 11. The treatment technology is not intended for industrial sources of wastewater. The treatment technology is intended to receive domestic wastewater with TL1 concentrations (see Table 6-3 in Regulation 43) exiting the septic tank. Wastewater with higher concentrations will require verification of the products ability to treat the wastewater and appropriate modifications or pretreatment. 12. Design shall provide access for maintenance and repair. As per the requirements of Regulation 43, septic tanks and all treatment components, other than the soil treatment area, shall be equipped with access manholes and risers that extend to or above final grade. All risers and lids shall be watertight and secure. Additional Operation and Maintenance Criteria 1. Design shall include an Operation and Maintenance (O&M) Manual to be provided for all installations. Individual operation plans shall include scheduled inspections, assessments, and maintenance of the treatment. This plan for scheduled inspections and assessments should include a routine inspection as described in section 43.14(D)(4)(b) unless the local regulations require more frequent inspections. The owner of the OWTS is responsible for arranging proper design, operation, and maintenance of the facility to achieve the desired treatment level. Joe Soulia, Orenco Systems Inc.

Wastewater from the home flows to the tank, where natural biological and physical processes provide primary treatment. In the primary chamber of the tank, the wastewater separates into three layers: a floating scum layer, a bottom sludge layer, and a relatively clear layer of liquid effluent in the middle. From the secondary chamber, a pump draws liquid effluent through the Biotube® filter and sends it to the AX20 pod. There, the effluent is sprayed over hanging sheets of porous synthetic textile media. Microorganisms live in this moist, oxygen-rich (aerobic) environment. As effluent trickles over and through the sheets, the microorganisms remove impurities from it. Effluent recirculates between the tank and the AX20 pod. In Mode 1, the most common configuration, the effluent recirculates to the second compartment of the tank. In Mode 3, effluent recirculates to the first compartment. This mode is used where maximum removal of nitrogen from the effluent is required. After recirculating several times, the effluent is discharged, either directly from the processing tank or after first being collected in a pump basin. Depending on the design for a particular site, the treated effluent may be discharged to a drainfield, an underground drip irrigation system, a constructed wetland, an effluent sewer (STEP) system, or a reuse system. The system may include equipment for ultraviolet (UV) disinfection before ultimate dispersal of the effluent. Properly sited, installed, and operated, a Residential AdvanTex Treatment System can treat wastewater to 10 mg/L BOD and 10 mg/L TSS. This level of treatment is better than what municipal wastewater plants provide. The system can also be configured to reduce nitrogen levels as required locally. When effluent treated in this way is dispersed to the soil, natural processes purify it further, and it eventually returns to the underlying water table, where it can be used again.

It also acquaints you, the service provider, with each individual system, so that you are familiar with any special components or requirements. The AX20 Start-Up Checklist (SCL-ATX-OM-1), shown on the preceding page, will help you remember to complete all the steps needed to check the system’s functions. While you don’t need to return the Start-Up Checklist to Orenco, we recommend bringing a copy to the start-up and checking off the steps to make sure that you perform all of them. As part of the start-up, you’ll also download a computer-generated Start-Up Summary Report from advantexservice.com and fax it to the fax number on the bottom of the form. An automated system will add the report to the data file for that system on advantexservice.com. This will confirm that the system is ready for operation, so that Orenco and the AdvanTex Dealer can confidently warranty it and your service contract can begin. Planning the Start-Up When the installer calls to tell you that the system is ready for start-up, ask the following questions: • Did the electrician connect the panel to the home’s electrical service and turn the power on? • Did the installer test the control panel to make sure it was functional? • Is there phone service, or, at minimum, is the phone line physically connected to the panel? If the installer answers “yes” to these questions, then the system is ready for start-up. A typical start-up visit takes about an hour. Arrange to meet the system installer at the site so that he or she can answer any questions you may have about the installation. The installer should bring the site plan or as- built. If the system owners can be present too, this is a good opportunity for them to learn how the system functions. As part of the start-up, you will need to review the Homeowner Package with the homeowners or, if the house has not yet been sold, with a representative of the homebuilder. You can do this at the start-up visit, or arrange a meeting prior to the start-up. Before Leaving the Office Download the Start-Up Summary Report from www.advantexservice.com. The top of the form should be pre-filled with information about the site. If any information is missing, fill it in. You will fill out the rest of the form at the site as you go through the start-up procedure. If the system does not have a discharge tank or basin and discharge pump, note that in the Start-Up Summary Report. At the Site Ask the system installer about the size, material, and manufacturer of each primary tank and discharge tank or basin, and record it on the Start-Up Summary Report. Also record the serial number(s) of the AX20 pods.

L Proper inlet tee installed. In the inlet riser of the primary processing tank, make sure that the inlet tee is present, firmly attached, and plumb. L Discharge plumbing properly installed. In the outlet riser, make sure that the discharge plumbing is properly installed through a watertight grommet. The threaded connections should be hand-tight, and the ball valve should be open. Look at the pump to make sure that it is the model specified on the plans, and record the model on the Start-Up Summary Report. L Float assembly mounted in Biotube® vault. L Floats operate properly. Before you test the floats, open the control panel and place it in test mode by pressing and holding the red button on the front for 15 seconds. Inside the panel, the correct yellow digital input LED should light up. Release the button when the audible alarm chirps. If you can’t see the inside of the control panel while you raise and lower the float switches, you may need a helper. Pull the float tree out of the water. The floats will go down, the alarm will sound, and all the yellow LEDs should be off. Raise the bottom float to stop the alarm. A yellow LED should light up. Next, raise the middle float, if it is present. No alarm should sound, but another yellow LED should light up. When you raise the top float, the alarm should sound again and the third yellow LED should light up. L Floats set properly. Replace the float tree in its bracket, making sure it’s properly mounted. Neatly coil the float cords, and secure them to the splice box. Measure the float heights from the outside top of the tank and verify that the heights are correct according to the AX20 Installation Guide. Record them on the Start-Up Summary Report. L Splice box mounted on access riser. Watertight connectors used. Inspect the splice box to make sure that it is securely mounted inside or outside the riser; that connections have been made using watertight wire nuts; and that there is no water in the splice box. We also recommend that you seal the conduit using conduit seals or any electrically approved sealant. NOTE: Orenco provides float and RSV settings for all tanks approved for use with AdvanTex Treatment Systems in your area. At start-up and during annual maintenance, you need only verify that the actual settings on the equipment match Orenco’s recommendations. If you need to adjust the settings to solve a problem, see Appendix 2. Completing the Start-Up Checklist (continued) WARNING: Do not enter the tank. Entering a tank without proper confined space procedures and equipment can cause serious injury, asphyxiation, or drowning. AIM-OM-ATX-1, Rev. 1.2, 03/14 • Copyright Orenco Systems®, Inc.

Do not reproduce or distribute without written authorization from Orenco: 800-348-9843. 10 AdvanTex® O&M MANUAL PART 1: START-UP AND ROUTINE MAINTENANCE L Pump operates in Manual. L Pump operates in Automatic. L Pump amps and volts checked. At the control panel, with the panel still in test mode, check the run amperage of the recirculation pump and discharge pump by placing the clamp of an ammeter around the wire to each pump’s circuit breaker and reading the amperage while each pump is running. You can run the pump by holding the toggle switch on MAN. Amperage should be no more than the pump’s maximum service factor amperage. First for the recirculation pump and then for the discharge pump, measure the voltage with the pump off, by putting the probes of a voltmeter on each pump’s terminals. Then measure the voltage with the pump running. The difference between running and rest voltage should be no more than 3 percent. That is 3.6 volts for a 120-volt system, or 7.2 volts for a 240-volt system. Release the switch back to the AUTO position. Make sure the pump comes on as the timer cycles. Timer cycles are shortened to about 30 seconds in test mode. Secondary Treatment L Verify proper RSV setting. Measure the distance from the outside top of the tank to the top of the Recirculating Splitter Valve (RSV) ball cage, and record it on the Start-Up Summary Report. L All pods installed level. L All piping properly covered and compacted. Check that each AX20 pod is installed level and that all piping is covered with compacted fill. L Ventilation intake(s) properly located and installed. L Squirt height verified. Open each AX20 pod and make sure that the ball valves at the end of the laterals are closed. Remove an orifice cover and measure the squirt height. Record the squirt height on the Start-Up Summary Report as “Residual Head Measurement.” L Discharge basin/tank inspected for infiltration. L Discharge basin/tank set level. Inspect the discharge pump basin or tank to make sure that it is set level and there is no sign of water infiltration. L Pump and discharge plumbing are compatible. L Discharge plumbing properly installed. Look at the pump to make sure that it is the model specified on the plans, and record the model on the Start-Up Summary Report. Verify that the discharge plumbing is installed as specified on the plans; that it is properly installed through a watertight grommet; and that the ball valve is open.

L Discharge floats set properly. Check the function and settings of the floats in the discharge basin/tank as described under Primary Treatment Components, and record the float heights on the Start-Up Summary Report, as before. L Splice box mounted in discharge access riser. Watertight connectors used. Inspect the splice box in the discharge basin/tank to make sure that it is securely mounted inside or outside the riser; that connections have been made using watertight wire nuts; and that there is no water in the splice box. Use conduit seals or electrically approved sealant. L Discharge pump operates in Manual. L Discharge pump operates in Automatic. L Discharge pump amps and volts checked. Test the discharge pump and check running amps, running volts, and resting volts at the same time you check the recirc pump. L Flow rate verified. L Dose volume verified. Determining the discharge pump’s actual flow rate enables you to determine the dose volume (the volume of wastewater being treated in each dose) and to calculate timer settings. Knowing the dose volume also enables you to determine the volume of wastewater being treated in a given period. To do this, multiply the dose volume by the number of doses. To verify the flow rate, follow Steps 1 through 7, then verify the dose volume in Step 8. Step 1. Determine the gallons per inch (gpi) or liters per centimeter (L/ cm) volume of the dosing tank or basin. A 24-inch (600-mm) diameter basin holds 1.88 gpi (2.8 L/cm). A 30-inch (750-mm) diameter basin holds 2.96 gpi (4.4 L/cm). For tanks, consult the manufacturer’s volume chart. For Orenco fiberglass tanks, use Fiberglass Tank Volume Charts, NCH-TNK-1. Step 2. You’ll be running the pump for one minute during the flow rate test, so check the liquid level inside the tank/basin to ensure that there’s enough water above the pump’s minimum liquid level (MLL), or the lowest float (whichever is higher), to complete the test. For example, in one minute, a pump operating at 10 gpm (37.8 L/min) will draw down approximately 5¼ inch (14 cm) of liquid in a 24-inch (600-mm) diameter basin, or 10 gallons ÷ 1.88 gpi = 5¼ inch, or 37.8 liters ÷ 2.8 L/cm = 14 cm So, to perform a flow rate test with the pump and basin in this example, you’d need at least 5¼ inch (14 cm) of water above the MLL or the bottom float (whichever is higher). If there is not enough liquid, add some. Step 3. If your system isn’t configured to drain back to the basin after each dose, skip to step 4. If your system is configured to drain back to the basin, you’ll need to account for the drainback volume in your calculations. Or you can stop drainback during the test by temporarily installing a threaded check valve between the pump and the pump dis- charge assembly. This eliminates the need to measure drainback volume. Step 4. To measure the flow rate, first measure the distance from the top of the tank or basin to the liquid level. Record this as H1. Step 5. Using a stopwatch, hold the discharge pump’s toggle switch on MAN for exactly one minute. Then switch off the pump. If the system is configured to drain back into the tank or basin after a dose, wait until drainback is complete. Completing the Start-Up Checklist (continued) NOTE: To ensure proper system operation, check to make sure that floats are Orenco “A” or “V” floats.

Measure the new distance from the top of the tank or basin to the liquid level. Record this as H2. Step 7. To get the pump’s flow rate, find the difference between H2 and H1. Multiply this number by the gpi (or L/cm) volume of the tank or basin. Add the drainback volume (DB), if applicable. Then divide by the pump run time in minutes (T). For this test, the pump run time in minutes should equal one minute. Step 8. To verify the pump’s dose volume, multiply the pump’s flow rate (gpm or L/min) by the pump run time in minutes (T) — as determined by float settings or timer operation, depending on panel model — and subtract the drainback volume, if applicable. Dose Volume (V) = (gpm × T) - DB or Dose Volume (V) = (L/min × T) - DB Other System Components L Disinfection equipment installed properly. L Dispersal equipment operating properly. Verify that any disinfection and dispersal equipment specified on the plans is present, and follow the manufacturer’s instructions to inspect it for proper functioning. Record the disinfection equipment manufacturer and the dispersal system type on the Start-Up Summary Report. Control Panel L Proper timer settings. Open the control panel and, using a handheld or laptop computer, verify that the timer settings are appropriate for the installation. Record the Panel ID (RTU or UL number) and timer settings on the Start-Up Summary Report. Default timer settings are set for an occupancy of 3 people. This may also be adjusted at vericomm.net, for systems equipped with VeriComm. L Proper wire size used based on information provided by manufacturer. For Orenco components, the panel installation instructions provide correct wire sizes. L All electrical connections in panel secured. L Panel wired per manufacturer’s wiring diagram. Check the panel to make sure that it is wired according to the diagram clipped inside the panel’s door. Gently tug on the wires to make sure they are secured in the terminals. L Service provider name/number written on “For Service Call” label. Write in your company’s name and phone number, if it hasn’t been done already. Completing the Start-Up Checklist (continued) Important: For VeriComm® panels, enter the gpm value on the “Site Details” page at vericomm.net as “Discharge Pump GPM.” The VeriComm panel will use it to automatically calculate and record the system’s actual flow rates, which can be used for reports, troubleshooting, and determining timer settings.

AX20 systems need a six-month visit, a one-year visit, and annual visits* thereafter. AX20N systems require four visits during the first two years and annual visits* thereafter. Failure to provide required maintenance will void the AdvanTex Treatment System warranty and may place the system out of compliance with local regulations. Homeowner Communication Whenever possible, contact the residents when it’s time for a service visit, especially if the residents are new to the home. The service visit is an opportunity to talk with them about proper use of the system, so try to schedule the visit when someone will be there. Retrieve O&M Info Download the Field Maintenance Report form for your site from www.advantexservice.com. The top of the form should be pre-filled with information about the system. Perform Field Sampling/Observations When you arrive at the site, remove the lids from the risers and take your sample before doing anything else, so that the sample won’t be contaminated by material that you stir up while working. To sample effluent, remove the Recirculating Splitter Valve (RSV) from its quick-release holster and set it aside. There will be enough of a trickle through the RSV plumbing to collect a sample without waiting for the pump to cycle. Wash down, brush, or wipe the RSV inlet before taking the sam- ple so there will be no contam- ination from dislodged solids. Leave the RSV disconnected for the rest of the service call so that any debris you stir up does not make its way to the drainfield. L Clarity of sample Assess the clarity of the sample by using a portable turbidity meter. *Servicing intervals may vary according to local regulations. L Odor of sample Sniff the sample and assess its odor. Record these observations about clarity (NTUs) and odor on the Field Maintenance Report form. L pH of sample L Dissolved oxygen of sample Using pH test strips or a pH meter, check the pH of the sample and record it on the Field Maintenance Report form. Values from 6 to 9 are normal. Also check the sample’s dissolved oxygen (DO) using a DO meter (or DO field test ampoules), and record that on the form. Values from 2.5 to 6 mg/L are normal. L Oily film in PVU L Foam in tank Check the liquid in the pump vault (PVU) for an oily sheen, and the liquid in the first compartment of the tank for foam or other unusual appearance. Record your observations on the Field Maintenance Report form. Performing Scheduled Field Maintenance IMPORTANT: To avoid contamination, do not run the pump manually or in test mode to obtain this sample. WARNING: Follow the precautions below when performing field maintenance on AdvanTex Systems. • Do not enter the tank. Entering a tank without proper confined space procedures and equipment can cause serious injury or death. • Use proper personal protection equipment, such as rubber gloves and eye protection, as well as protective clothing, to cover parts of the body that will be exposed to wastewater or effluent. • When working on components that contact sewage or effluent, lay them on a plastic sheet or place them in a trash can, not on the lawn. Several tools that reduce the mess of cleaning Biotube® filters and AdvanTex textile sheets are available from Orenco. • Turn off power to electrical components when working in splice boxes or the control panel or when disconnecting pumps. • When finished, use proper personal hygiene. NOTE: If field sample levels are outside of the norm or if your observations indicate the treatment system may not be functioning properly, further testing in a laboratory environment may be needed. Sampling equipment, minimum sample size, and storage procedures should conform to the standard methods required by your federal, state, and local authorities.

L Run amperage Check and record the run amperage of the recirculation pump and discharge pump. Place the clamp of an ammeter around the wire to each pump’s circuit breaker and read the amperage while each pump is running. You can run the pump by holding the toggle switch on MAN. Amperage should be no more than the pump’s maximum service factor amperage. Release the switch to the AUTO position. Make sure the pump comes on as the timer cycles. Timer cycles are shortened to about 30 seconds in test mode. L Audible and visual alarms Check the operation of the floats and timers by lifting the float trees out of the tank and discharge basin and following the instructions clipped inside the panel door. Make sure that audible and visual alarms are activated when the appropriate float is raised or lowered. L Dial tone (telemetry only) For systems equipped with VeriComm® panels, use a phone line tester or a phone to verify the presence of a dial tone. Inspect/Clean Recirc Pump System L Riser/Lid Make sure that the lid is intact, and replace it if necessary. Replace any missing lid bolts. Check for marks of liquid infiltration or exfiltration. L Splice box Open the splice box and make sure there is no water in it. If there is, remove the water with a sponge and repair the leak. If you disconnect any connections, do not reuse the wire nuts when you reconnect them — use new ones. L Float cords L Floats Verify that the floats are in good condition and properly secured to the float tree. Verify that float cords are neatly wrapped inside the riser so that they cannot interfere with the operation of the floats. Clean floats by hosing or brushing them so that debris falls back into the tank, not into the pump vault. L Pump Turn circuit breaker off at service panel. Switch MOA and circuit breakers in control panel to “Off.” Pull the pump and place it on a cleanable surface, like the riser lid, or in a plastic trash can. Check the intake screen; wash off particles as necessary. Record the kinds of particles in the Comments section of the Field Maintenance Report form and report findings to user (for preventive maintenance). Reinstall the pump, checking to make sure the discharge valve on the hose and valve assembly is open. Performing Scheduled Field Maintenance (continued) Copyright Orenco Systems®, Inc.

Make sure that the RSV is out. Slide Biotube cartridge out of vault. Hold Biotube cartridge over open inlet of tank or primary compartment. Carefully spray build-up into tank. (The Biotube Cradle, available from Orenco, holds the Biotube Filter on the lip of the riser and directs debris into the tank away from the pump vault.) Flush vault bottom. L Recirculating Splitter Valve Move the RSV from side to side to check that the balls move freely. Then verify that the liquid level in the tank is within the normal range. If it is low, the ball mechanism could be jammed in the seated position. If it is high, the RSV may not be making a tight seal when the balls are seated. Clean the balls and replace the balls or the cage if necessary. Don’t replace the RSV in the tank until you’re ready to leave the site. Measure Sludge/Scum Measure sludge and scum in both compartments of the tank, and record the measurements on the Field Maintenance Report form. Schedule pumping of the tank when the bottom of the scum layer is within 3 inches (75 mm) of the flow-through port of the tank baffle or when the sludge accumulates to within 6 inches (150 mm) of the flow-through port. Note any unusual appearance or smell of the tank’s contents, and consult the Advanced Service Tips and Troubleshooting Guide, available from your AdvanTex Dealer, if necessary. If you find kitty litter, sanitary products, excessive grease, or other material that shouldn’t be in the tank, talk to the residents of the home and remind them not to flush those things. Inspect/Clean AdvanTex Filter Open the AdvanTex Filter pod. L Odor L Biomat L Bridging/Ponding Check that the odor and appearance of the biomat are normal. Pungent or unusual odor, ponding (excessive liquid), and bridging (excessive solids) are problems that need immediate attention. The Advanced Service Tips and Troubleshooting Guide can help you ascertain the cause. You may need to change the timer settings or discuss household habits with the system users. And you may need to clean the filter sheets. (See “Additional Services Rendered.”) L Laterals/Orifices Inspect the orifice shields. A clean area around an orifice cover is a sign of a plugged orifice; clean these orifices out before cleaning the laterals. To clean and flush the manifold, open the flush valves at the ends of the laterals and brush or jet the laterals. L Pod bottom Pull out a few sheets, inspect the pod bottom, and note any excessive buildup of debris. When you’re done cleaning the manifold, remove the RSV from the tank, and run the pump for two or three minutes with the flush valves open and the RSV removed to flush debris from the pod’s underdrain back into the tank. You can do this while you are performing other tasks. After flushing, close the flush valves and make sure the orifice covers are on more or less straight. Replace the RSV in the tank. L Intake vent Make sure that the ventilation intake is not damaged or blocked, and clean or replace it if necessary.

Clean floats and pump by hosing them. If you pull the pump, check to make sure the discharge valve is open after reinstalling. Over time, solids may accumulate in the discharge basin. Use a trash pump to pump these solids into the inlet end of the processing tank. Inspect/Service Other System Components L Disinfection equipment L Dispersal laterals/orifices Follow the manufacturer’s instructions to inspect and service other components of the system. Additional Services Rendered L Cleaned textile sheets? You should not need to clean the textile sheets every year, but it may be necessary now and then. Don’t clean them unless the buildup of biomat is bridging across the sheets, because removing too much of the biomat inhibits the system’s treatment performance. If you need to clean the sheets, remove the RSV so that solids can freely drain back to the tank. Then clean the sheets one by one with the AdvanTex Cleaning Wand, a hose, or a backpack pressure washer (at low pressure). Wash debris down into the pod, where it will drain back into the processing tank. L Replaced UV items? L Replaced/used other items? Document any equipment replaced and any additional observations. Final/Safety Inspection Review the Field Maintenance Report form to ensure all activities have been performed. L RSV reinstalled If you haven’t done so already, reinstall the RSV. L Manifold reconnected and valves closed Make sure that the flush valves at the ends of the AX20 laterals are closed. L Lids bolted on Replace all lids and tighten all lid bolts.

Appendix 2: Float and RSV Settings (continued) Typical RSV Levels For stinger pipe lengths up to 24 inches (600 mm) long, the “normal low operating liquid level” will be approximately 5-6 inches (125-150 mm) below the top of the RSV cage. (The normal low operating liquid level is the level at which 100% of the filtrate returns to the tank.) For most residential applications, the recommended surge volume — the volume between the low liquid level and the high water alarm float — is approximately 250 gallons (950 L). For Mode 3 installations, the duckbill model RSV, which has a flexible PVC tube that vents the RSV cage to atmosphere, is required. Typical Float Levels Be sure to check the plans for any site-specific or tank-specific float settings. The top float is normally set equal with the tank’s invert of inlet. The bottom float should be approximately 4 inches (100 mm) below the normal low operating level. NOTE: Before leaving the site, verify that the “low water alarm/redundant off” float is positioned at least 10 inches (250 mm) below the top of the RSV cage.

Orenco has always advocated regular, professional servicing of all onsite systems ... not just during the warranty period but for the life of the system. Regular servicing optimizes the treatment process and protects the property owner’s investment. It also ensures that onsite systems protect public health, protect the environment, and are viewed as a reliable, sustainable technology. Orenco relies on you to perform the AdvanTex system start-up, do routine (scheduled) maintenance, and respond to calls for unscheduled maintenance (alarm calls). We also rely on you to keep in contact with the homeowners or property owners, review the Homeowner’s Manual with them, advise them on preventive maintenance, and work to keep the system under a continuous service contract. Equally important, we rely on you to keep good service records on the system, creating a “history” of its performance. To make your job easier, Orenco has created one of the most service-friendly and trouble-free onsite systems on the market. AdvanTex is a packed bed (media) fi lter. And media fi lters are the most suitable technology for onsite wastewater treatment because they are reliable and provide consistent, high-quality effl uent. We then paired our media fi lter with a remote telemetry control panel, to allow you to “view” the system right from your computer. And we’ve provided a Web-based business tool — advantexservice.com — to help you fi le and retrieve system data automatically, schedule service events, and manage service technicians. Finally, we’ve provided classroom and fi eld training, as well as support materials, like this O&M Manual. Please read it thoroughly, and refer to it often. We’re very proud of our AdvanTex Treatment System. Like all our products, it has gone through extensive research, development, and fi eld-testing. Then each component is built to written specifi cations and subjected to quality review, before shipping. In addition, our AXN models meet the requirements of NSF- ANSI Standard 40 for Class I Systems. Thank you, in advance, for your knowledge, your conscientiousness, and your good work.

Wastewater from the home fl ows to the tank, where natural biological and physical processes provide primary treatment. In the primary chamber of the tank, the wastewater separates into three layers: a fl oating scum layer, a bottom sludge layer, and a relatively clear layer of liquid effl uent in the middle. From the secondary chamber, a pump draws liquid effl uent through the Biotube® fi lter and sends it to the AX20 pod. There, the effl uent is sprayed over hanging sheets of porous synthetic textile media. Microorganisms live in this moist, oxygen-rich (aerobic) environment. As effl uent trickles over and through the sheets, the microorganisms break down the contaminants and eliminate them. Effl uent recirculates between the tank and the AX20 pod. In Mode 1, the most common confi guration, the effl uent recirculates to the second compartment of the tank. In Mode 3, effl uent recirculates to the fi rst compartment. This mode is used where maximum removal of nitrogen from the effl uent is required. After recirculating several times, the effl uent is discharged, either directly from the processing tank or after fi rst being collected in a pump basin. Depending on the design for a particular site, the treated effl uent may be discharged to a drainfi eld, an underground drip irrigation system, a constructed wetland, an effl uent sewer (STEP) system, or a reuse system. The system may include equipment for ultraviolet (UV) disinfection before ultimate dispersal of the effl uent. Properly designed, installed, and operated, a Residential AdvanTex Treatment System can treat wastewater to 5 mg/L BOD5 and 5 mg/L TSS. This level of treatment is better than what municipal wastewater plants provide. The system can also be confi gured to reduce nitrogen levels as required locally. When effl uent treated in this way is dispersed to the soil, natural processes purify it further, and it eventually returns to the underlying water table, where it can be used again.

If treatment performance fails to meet that standard, the cause may be the design, installation, settings, or use of the system — or more likely, a combination of those factors. Here’s what happens in each part of the system, and how each of these factors can keep the system from performing as well as it should. Processing Tank Primary treatment happens in the tank, and several conditions inside the tank affect the ultimate effl uent quality. The fi rst is the incoming wastewater: its strength (concentration), mass loading (amount of each wastewater component), hydraulic loading (volume), and chemical characteristics. Residential wastewater (raw infl uent) typically has BOD5 of 450 mg/L, TSS of 500 mg/L, and total Kjeldahl nitrogen (TKN) of 70 mg/L. Practices in the home may raise the levels of these components and may also introduce harmful chemicals and indigestible solids into the system. Although the AdvanTex system is robust enough to accommodate a houseful of weekend guests or a couple of days of canning, residents must be aware that in the long run, certain habits can harm their septic system or increase the need for system servicing and/or pumping. The Troubleshooting section of this manual lists some household practices to inquire about when a system has problems. In addition to the composition of a home’s effl uent, the size of the tank and the volume of the effl uent also affect performance. Residential systems are sized and designed to accommodate the North American average of 50-60 gallons per person per day and are sized for a certain number of residents. A change in the number of residents, or a sudden increase in their water use per capita, can push wastewater through the tank without allowing the minimum 24 hours of retention time required for thorough separation and digestion of wastes. Finally, the tank and all pipe joints must be watertight to prevent both infi ltration and exfi ltration of liquid. Infi ltration of rainwater or groundwater will overload the system, preventing proper stratifi cation in the processing tank and overloading the AdvanTex textile fi lter. Exfi ltration of liquid effl uent from the tank can make liquid levels too low for stratifi cation, leading to clogging of the Biotube® effl uent fi lter. Of course, exfi ltration also pollutes the soil, and potentially the groundwater. AdvanTex Textile Filter The AdvanTex textile fi lter provides secondary wastewater treatment. The fi lter is a sturdy, watertight fi berglass basin fi lled with a nonwoven textile material. This lightweight, highly absorbent media treats a large amount of wastewater in a small space because it has a very large surface area — about fi ve times greater than that of an equivalent volume of sand, for example. Textile also has a greater void volume (for free fl ow of oxygen) and greater water-holding capacity. These properties make it an excellent environment for aerobic micro- organisms to live and digest the nutrients in effl uent. As effl uent from the processing tank percolates through and between the sheets of textile, the microorganisms remove what they need from it, reducing BOD5 and TSS. Also, the aerobic conditions within the AdvanTex fi lter are ideal for microbes that convert ammonia to nitrates (nitrifi cation). For sites where maximum denitrifi cation is necessary, AdvanTex fi lters can be confi gured in Mode 3, so that the fi ltrate recirculates back to the high-carbon, low- oxygen environment at the inlet end of the processing tank, which is ideal for microbes that reduce nitrates to nitrogen gas (denitrifi cation). Harmless nitrogen gas is then released back into the atmosphere. In addition to being affected by oxygen, the AdvanTex fi lter’s performance is affected by mass loading, hydraulic loading, strength, and chemical characteristics of the infl uent. If the effl uent coming from the processing tank is contaminated with harsh chemicals or excessive grease, the biomat of microorganisms will suffer. The graphs on the next page show that low-to-moderate loading rates produce BOD5 and TSS of <5 mg/L, and higher loading rates produce BOD5 and TSS in the range of 15-25 mg/L. About Recirculation Ratio Maintaining an appropriate recirculation ratio is important for proper functioning of the system. Adjusting the frequency and length of the doses of effl uent delivered from the tank to the AdvanTex fi lter optimizes the conditions for the microorganisms. A recirc ratio that’s too high can generate a highly aerobic biomat growth on the pump fi lter. It also increases alkalinity consumption and dissolved oxygen concentration in the processing tank, which can inhibit denitrifi cation. Conversely, a recirc ratio that’s too low can tend to liberate periodic odors during dosing events. The optimum ratio is typically between 2:1 and 6:1.

Low Effl uent Quality If your effl uent samples are cloudy and color/turbidity is signifi cantly higher than expected (greater than 15 NTU), do the following: Check the Biotube® fi lter for clogging. Check to see if the textile fi lter smells of chemicals (medication, chlorine, etc.) or has a granular or crusty appearance. (For example, a white crystalline crust could signal that water softener discharge or industrial strength detergents have been fl ushed into the system.) Check to see if the recirc ratio is too high or the pump dose time is too long. If the effl uent cBOD5 is high and TSS is low, a large amount of soluble cBOD5 has not yet been consumed. That would likely be because the recirc ratio is too low for the infl uent strength or insuffi cient start-up time has elapsed. Typical organic reduction within the fi rst 24 hours in residential systems is about 75% or greater. As the biomat begins to develop, greater reductions in the soluble cBOD5 will occur (typically within the fi rst 7-10 days). With a higher infl uent strength, the soluble cBOD5 would not be readily removed until the biomat on the media is established. Check that ventilation is occurring, at the pod and from the house to the tank. Interview the users about system abuse, especially in the area of harmful chemicals, solvents, strong cleaning agents, or water softener backwash. • • • • • If none of these troubleshooting steps makes a difference, lab tests may be necessary to determine the cause of the problem. Call Orenco for recommended lab tests or design remedies. Odor If the tank or textile fi lter smells like rotten eggs or cabbage: Check dissolved oxygen levels using a DO meter or DO wet test kit. Note fi ltrate DO levels that are <2.5 (less than 2.5) or >6 (greater than 6) mg/L. Filtrate DO that’s <2.5 mg/L indicates insuffi cient oxygen. If the fi ltrate DO is <2.5 mg/L: Check fi lter surface for evidence of clogging. Check that the pump is working. Check that ventilation is occurring, at the pod and from the house to the tank. Check that the recirc ratio isn’t too low; increase if too low. Check that infl uent strength isn’t too high (see AdvanTex Design Criteria). Check to ensure hydraulic retention time isn’t too high. Filtrate DO that’s >6 mg/L indicates excessive aeration. If the fi ltrate DO is >6 mg/L: Check to ensure recirc ratio isn’t too high. Check to see if infl uent fl ows are below normal. If infl uent fl ows are below normal or recirc ratio is too high, reduce recirc ratio. • • • • • • • • • • • Troubleshooting Effl uent Quality Special Note about Water Softeners: Water softener backwash is extremely high in salts, which can disrupt system performance, especially nitrogen reduction processes. Talk with residents to make sure that no water softener backwash is discharging into the processing tank. Plumbing water softener backwash into the processing tank voids the warranty.

Ensure the recirc ratio isn’t too high. Verify normal DO levels; if high, reduce recirc ratio. Check for below normal infl uent fl ows. Check infl uent Grease & Oil and TSS; if excessive, a review of component sizes may be required. • • • • • Oily Film All signs of oil or grease anywhere in the system (in the tank, in the vault, on the effl uent fi lter or textile fi lter) must be investigated. Ask the system user to identify the probable source: Recent change of car oil? Canning meat or poultry? Excessive use of garbage disposal? Excessive use of bath or mineral oils? (Jacuzzi® tub?) Excessive use of detergents? If the system user can’t identify the probable source, try the following: Sample and test at all process steps, including infl uent (if possible). Label, date, and photograph all samples. — When photographing, use standard glass beakers and set samples in front of a common, uniform background Check biomat accumulation at AdvanTex Filter. Note if biomat is yellowish and wax-like or lard-like. If so, scrape biomat sample for analysis: — Photograph/document biomat sample. — Send to lab with effl uent samples.

Because many people purchase AdvanTex for its nitrogen-reducing capabilities, and because nitrogen reduction is a complex, many-staged process, it’s important to understand the process, its related factors, the signs of effective nitrogen reduction, and how to keep the process optimized. It’s also important to know the TN limits required by the system user’s permit. Some regulatory agencies have no requirement; some require a specifi c percentage reduction of a certain kind of nitrogen (90-95% nitrifi cation of ammonia nitrogen, for example); and some require that TN be reduced to levels at or near drinking water quality at the point of fi nal dispersal. A level of 20 mg/L TN is becoming increasingly accepted by regulators because it’s typically achievable without relying on supplemental carbon and alkalinity feeds. Finally, because infl uent characteristics greatly affect the amount of nitrogen reduction possible from any given system, it’s vital to know the alkalinity of your waste source and the local or regional norms for organic and ammonia nitrogen. The Process Appendix 1 describes the nitrifi cation/denitrifi cation cycle in more detail, but a brief description should help you with most troubleshooting. In nitrogen reduction, ammonia is converted to nitrate in an aerobic environment, and then reduced through bacterial action in an anaerobic environment to nitrogen gas, which is released harmlessly to the atmosphere. Optimum nitrogen reduction typically requires the following: Adequate alkalinity of approximately 250 mg/L or higher (a lab test shows levels). pH of 6-9. Fixed-fi lm microbial processes generally thrive between pH 6 and 9. Treatment problems typically result from rapid changes in pH rather than extreme long-term mean values, although long- term levels can result in less effi cient process activity. Filtrate DO level of 2.5-6 mg/L, process tank DO level of <1 mg/L. Adequate time for the nitrifying bacteria to develop (one to three months). Adequate temperature (below 40° F retards the process). Good organic removal. For a thorough description of the nitrogen reduction process, see Appendix 1. In residential wastewater, the ammonia level is typically about 60 mg/L and the TN is typically ≈70 mg/L. Signs of Effective Nitrogen Reduction Service providers frequently ask us, “How do I know if my wastewater treatment system is reducing nitrogen?” A thorough description of key indicators is included in Appendix 1. Following is a brief summary: Clear, odorless fi ltrate effl uent (a “see and sniff” test is generally considered suffi cient). Normal-looking biomat on the textile fi lter (light-brown to dark-brown and gelatinous in texture). Additional fi ltrate tests will show ... Typically, low BOD5, low turbidity and high clarity. DO of ≈ 2.5-6 mg/L. Low ammonia levels (≈<1-3) and relatively high nitrate levels, since nitrifi cation converts ammonia to nitrate. • • • • • • • • • • • Troubleshooting Nitrogen Reduction * Total Nitrogen (TN) is the sum of organic nitrogen (ON), ammonia nitrogen (NH3-N), nitrate nitrogen (NO3-N), and nitrite nitrogen (NO2-N). ** Total Kjeldahl Nitrogen (TKN) is the sum of organic nitrogen (ON) and ammonia nitrogen (NH3-N).

Filtrate Alkalinity Too Low — Suffi cient alkalinity is required to achieve the desired degree of nitrifi cation for any wastewater treatment system, because it takes 7.14 parts alkalinity to nitrify 1 part ammonia. If fi ltrate alkalinity is too low: Check the recirc ratio; a high recirc ratio increases alkalinity consumption. Check infl uent TKN or ammonia levels and source alkalinity. If a large quantity of nitrifi cation is required, it may be necessary to add alkalinity-raising chemicals to the system. Filtrate pH Too Low — Nitrifi cation is particularly sensitive to pH but tends to thrive at levels between pH 7 and 8. The nitrifi cation process releases hydrogen that consumes alkalinity and causes pH levels to drop. A pH level of <6 retards microbial activity of all kinds, including denitrifi cation, and with a pH level <5.5, nitrifi cation may show signs of degradation. Maintaining an alkalinity of 50 to 80 mg/L in the effl uent is typically suffi cient to maintain pH levels above 5.5. If the fi ltrate pH level is too low: Check infl uent alkalinity level (pH drops when too much available alkalinity is consumed). Check recirc ratios; reduce if too high. Ask system user about chemical discharges into the system, including carpet cleaners, chlorine, and photo developing agents. • • • • • Filtrate DO Levels Outside Range of 2.5-6 mg/L — If fi ltrate DO is too low (indicating insuffi cient oxygen), the system may release sulfi de odors during dosing events, or there may be a more lasting smell within the fi lter pod. Try the following: Check for surface clogging/ponding and clean as necessary. Check air fl ow through the vent assembly. Check the recirc ratio; if it’s too low (<2:1), increase as necessary. If your fi ltrate DO is too high (indicating excessive aeration), it’s likely that excessive recirculation or insuffi cient hydraulic retention time are factors. Try decreasing the recirc ratio. High Filtrate Ammonia Levels — Because ammonia is biochemically oxidized to nitrate during nitrifi cation, high ammonia levels are a sign that something is amiss. Try the following: Check for surface clogging/ponding and clean as necessary. Check for suffi cient aeration (measure DO). Ensure no blockage of air fl ow into textile fi lter (indicated by thick biomat development or a build-up of grease and oils). Ensure no blockage in the manifold, causing ... — Localized hydraulic overloading, saturation — Short circuiting Check for suffi cient alkalinity; if insuffi cient, consider supplemental buffering using equipment that automatically adds an alkaline compound to the system.

Therefore, the ammonia levels in the fi ltrate should be low and the nitrate levels higher. Some denitrifi cation occurs in the packed bed fi lter, so the normal nitrate level may vary. Be sure you are familiar with the mode of operation, as some AdvanTex modes are confi gured to produce lower nitrate levels. If it appears that nitrifi cation is dropping off: Check the recirc ratio; adjust as necessary (high recirc ratios may drive pH too low for effective nitrifi cation/denitrifi cation, and low recirc ratios may not provide suffi cient aeration). Verify incoming ammonia levels. Check recirc/blend for excessive organic food source (high BOD5 may cause greater oxygen demand through the fi lter, reducing nitrifi cation). • • • Adequate Time and Temperature — Nitrifying bacteria require one to two months to develop, and extremely cold temperatures (below 40° F) retard that process. If the AdvanTex Treatment System has been installed in a very cold climate, nitrifi cation may not “kick in” for several months until warmer temperatures are reached. Typically, a June-September installation provides the necessary temperatures for a 30-60 day nitrifi cation start-up time. Once nitrifi ers colonize, they typically continue to nitrify through normal winter conditions. Only in severely cold regions should additional insulation be necessary.

In nitrifi cation, ammonia is oxidized to nitrate (2NH3 converts to 2NO3 + 3H2O). This nitrate is then reduced through bacterial action (denitrifi cation) to nitrogen gas, which is released harmlessly to the atmosphere. During the nitrifi cation process, about 9 parts oxygen are consumed in converting 2 parts ammonia to nitrate. Therefore, depending on the concentration of ammonia, a considerable amount of air may be needed. Other processes, like BOD5 reduction, may occur simultaneously and further elevate the demand for aeration, especially if the organic level is high. In an abundance of air, all the aerobic or facultative microbes compete for their share of oxygen. When the organic concentration is high, the microbes that oxidize organic matter, primarily the heterotrophic bacteria, are aggressive and tend to outcompete other microbes for the available free oxygen in solution. Ammonia is oxidized by autotrophic bacteria, which do not have as aggressive a growth rate, so if oxygen is not abundant, nitrifi cation suffers. Consequently, the nitrifi cation process usually lags until the organic concentration is depleted or until suffi cient oxygen is present. At a 2.5:1 BOD5/TKN ratio, the nitrifi ers may only make up about 10 percent of the microbial population. At 0.5:1 BOD5/TKN, the nitrifi ers make up about 35 percent of the population. In a fi ltering process, the fi lter column must be deep enough, or the fi lter media must be effi cient enough at fi ltering organic particles, to deplete organic concentrations to a level in which a suffi cient population of nitrifi ers will be sustained. The physical (dimensional) features of the fi lter will vary depending on the media’s characteristics — void ratio, moisture holding capacity, and effective surface area per unit volume ratio. Tankage, surge capacity, application rates, and loading characteristics are other design considerations that play a role in the sizing of the fi lter unit. Performance Indicators To judge the nitrogen-reducing performance (or potential) of any wastewater treatment system, be sure to check the following performance indicators: Clear, Odorless Effl uent — Simple, “see and sniff” tests can be performed easily in the fi eld. Effl uent from packed bed fi lters (recirculating textile fi lters, recirculating sand fi lters, intermittent sand fi lters) that are performing well should be clear (with turbidity <20 NTUs) and odorless. Tests for Ammonia and Nitrate Nitrogen — If the system is oxidizing ammonia to nitrate (nitrifying), lab tests should measure relatively low ammonia levels and relatively high nitrate levels in the fi ltrate. Because nitrifi cation responds to many and varying conditions within the aerobic treatment processes, ammonia and nitrate nitrogen levels in the fi ltrate are the most ideal constituents to watch for any changes in performance. Start-up times can be plotted, optimum recirc ratios can be gauged, cleaning frequencies can be predicted, and nonvisible clogging or saturation can be detected by watching either of these constituents. Typical nitrifi cation in single-family residential systems is expected to be in the 98-99% range. Investigate if the process appears to degrade by 5 percentage points or more. BOD5 — The nitrifi cation process requires oxygen, which is why nitrifi cation is enhanced when BOD5 is extremely low. Measures of fi ltrate BOD5 should be <15 mg/L, although higher BOD5 may not necessarily correlate with low levels of nitrifi cation. Typical infl uent characteristics are shown on page 8. When BOD5 is high, there is a greater organic demand for oxygen, which may hamper the nitrogenous demand for oxygen. Increasing the recirc ratio should help establish oxygen balance.

The biomat should appear light-brown to dark-brown in color and gelatinous in texture. Dissolved Oxygen — Dissolved oxygen also provides critical information with which to diagnose how well a system is performing. Measures of DO should be in the range of 2.5 to 6 mg/L. If the DO level drops, the degree of nitrifi cation will normally drop as well, which could be a sign of blinding or saturated fl ow conditions — anything that might inhibit free air from fl owing into the system. (Nevertheless, it’s quite possible to have low fi ltrate DOs and still have high effl uent quality, as measured by BOD5 and TSS levels.) pH — For normal residential nitrogen loads, pH is typically maintained between 6 and 8. Infl uent Characteristics — Infl uent characteristics (see page 9) will greatly affect the amount of nitrogen reduction that is possible from any wastewater treatment system. High solids and/or fats and cooking oils increase the oxygen demand and accumulation of material on and within the media, affecting the available oxygen for nitrifi cation. Alkalinity — The nitrifi cation process releases hydrogen ions into solution, which tends to lower the pH level. Alkalinity is essential for nitrifi cation. For each part ammonia that is nitrifi ed, 7.14 parts alkalinity are consumed (buffering the acidity caused by the release of hydrogen ions). Consequently, if the degree of nitrifi cation is less than expected, it could simply be a lack of suffi cient alkalinity to support more. Typical residential nitrifi cation requires alkalinity above about 250 mg/L for recirculating processes and double that for single-pass processes. Many wastewater streams do not have suffi cient alkalinity to support complete nitrifi cation. In this case, nitrifi cation may deplete the alkalinity, and pH may drop to a level that retards the microbial activity (<6). Recirculating the effl uent helps, since half the alkalinity can be restored in the recirc or process tank, wherever denitrifi cation occurs (and adjusting the recirc ratios may also bring the pH back to preferred operating levels). But wastewater streams that are alkalinity-starved can’t provide for 100% nitrifi cation. The use of low fl ush fi xtures can reduce nitrifi cation performance. Low fl ush fi xtures tend to reduce hydraulic loads, which causes elevation of wastewater constituents (i.e., higher concentrations of BOD5, TSS, TKN, etc.). In this case, the available alkalinity in the water supply may not be adequate to accomplish the full level of nitrifi cation desired. These constraints exist for all wastewater treatment operations, regardless of whether the operation involves a suspended growth contact stabilization process or an attached growth packed bed fi lter. Packed bed systems will perform better, especially if they have a large attached growth surface area per unit volume ratio, because the micro-sites near the attached side of the biomat, where denitrifi cation typically occurs, return some of the alkalinity. Textile packed bed fi lters, because of their large surface area per unit volume ratio, tend to perform even better. Nevertheless, additional buffering may be necessary to accomplish the level of nitrifi cation desired. In low alkalinity conditions, pH adjustment can be made with the addition of quicklime or hydrated lime, soda ash, or caustic. If the alkali is to be introduced at a process point preceding sedimentation zones, such as in the tank, lime would be preferred. Soda ash and caustic both contain sodium, which is a dispersant and will impede settling of solids in the tank.

This test pit was excavated per Pitkin County Environmental Health Department comments on SGM's OWTS design for the property dated October 10, 2019. The proposed seepage pits are approximately 12.5 feet deep. A test pit in the range of 15-17 feet in depth was requested to investigate adequate separation from a limiting layer such as groundwater. Thank you for joining us on site for the test pit observation. When we arrived on site the excavator had prepared a test pit which we measured with a tape to be approximately 16-17 feet in depth. We examined the test pit from the top, as the surrounding steep slopes prohibited sufficient excavation to provide a test pit safe for human entry. The test pit soil profile appeared to be relatively consistent in texture and color, with visible cobbles and boulders, and lighter -colored topsoil. The soil at the bottom of the pit appeared to have less rock. We did not observe any groundwater in the test pit. The soil removed from the test pit was moist but did not appear to be saturated, and the bucket of the excavator did not smear the soil on the sides of the test pit. We did not see any other signs of seasonal groundwater, such as redoximorphic or gleyed features. One of the seepage pit precast cylinders had been installed. Thank you for your attention in this matter. Please feel free to contact us if we can provide any further information.

Assoc. Justin Excav. Svcs. FROM: Rick Barth, SGM on behalf of Will Comerer, PE DATE: December 12, 2019 – As-built January 2020 . Memo 2/20/20 RE: 1266 OCR OWTS field report and As-built verification 2017-283.001 The below is an exact transcription of Will Comerer’s field visit notes from the above date to inspect the operation of the installed OWTS system at 1266 Owl Creek Road. Please note the following:  We opened all lids of the tanks and advantex  The pump vault handle needs to be extended within 12” of the pump vault lid. Justin will provide photos to SGM and Pitkin County when it has been installed, probably next Monday.  Justin activated the pump in the secondary tank, I was able to see the pump running, and I saw the water being discharged from the re-circ. Line. I did not look in time to see the effluent being discharged into the pump basin. Justin did not have sufficient water in the tank to turn it back on for us. The tanks/pump vault did not seem to have be pre-filled as I had requested.  We could see the re-circ. line discharge in the first riser of the first tank.  We saw the tee installed in the second riser of the first tank.  We saw the ball float valve in the first riser of the second tank.  The floats we hooked up to the control panel, which was not yet hooked up to the phone line.  Both I and Strl. Assoc. will follow up with Rick about the phone line.  Justin cycled the pump vault pump after filling it with a hose.   118 W. 6th St, Ste 200 Glenwood Springs, CO 81601 Phone: 970-945-1004 Fax: 970-945-5948  We watched the ADV cycle back and forth between the two seepage pits.  There was not a ball valve on the discharge end of the re-circ. line. I will follow up with Strl. Assoc. about this.  Bryan and I located the seepage pit lids which are at grade. In January 2020 SGM conducted field survey and assembled the associated as-built map (attached) for the installed system. Of note, we include photos of the initial pump vault with handles extend up within easier reach (before: left / after: right showing the longer handles). The as-built verified the above noted points and field changes were minor. The Advantex filter AX20 were located near the tanks to preserve some trees but all boundaries and setbacks were still respected as per design. Some minor rockwork was installed the make grades more maintainable and accessible around the tanks. The general footprint of this small boulder course (all under height) is evident on this topography. With this memorandum and the updated OWTS site plan, we submit the installation is as designed and no changes are of note to the design parameters, function, or compliance with State and County regulations. Please do not hesitate to call if you have any questions. -RLB Ow l C r e e k R o a d Kbi 1266 Owl Creek Road 2.000 ac. ± 87111 sq. ft. ± Graphic Scale In Feet: 1" = 20' 0 10 20 40 Title: OWTS Plan Re v i s i o n # Dwg No. 12 6 6 O w l C r e e k R o a d Pi t k i n C o u n t y , C O Job No. Drawn by: Date: File: PE:QC: 2017-283.001 JB 10.10.2019 JWH OwlCreek-OWTS WC 11 8 W e s t S i x t h S t r e e t , S u i t e 2 0 0 Gl e n w o o d S p r i n g s , C O 8 1 6 0 1 97 0 . 9 4 5 . 1 0 0 4 w w w . s g m - i n c . c o m Da t e By : C.1.007 12Of : Fo r C o n s t r u c t i o n Pr o j e c t M i l e s t o n e : Graphic Scale In Feet: 1" = 5' 0 3 5 10 Title: OWTS Plan & Profile Re v i s i o n # Dwg No. 12 6 6 O w l C r e e k R o a d Pi t k i n C o u n t y , C O Job No. Drawn by: Date: File: PE:QC: 2017-283.001 JB 10.10.2019 JWH OwlCreek-OWTS WC 11 8 W e s t S i x t h S t r e e t , S u i t e 2 0 0 Gl e n w o o d S p r i n g s , C O 8 1 6 0 1 97 0 . 9 4 5 . 1 0 0 4 w w w . s g m - i n c . c o m Da t e By : C.3.001 12Of : Fo r C o n s t r u c t i o n Pr o j e c t M i l e s t o n e : C.6.002 Title: OWTS Details Re v i s i o n # Dwg No. 12 6 6 O w l C r e e k R o a d Pi t k i n C o u n t y , C O Job No. Drawn by: Date: File: PE:QC: 2017-283.001 JB 10.10.2019 JWH OwlCreek-Details WC 11 8 W e s t S i x t h S t r e e t , S u i t e 2 0 0 Gl e n w o o d S p r i n g s , C O 8 1 6 0 1 97 0 . 9 4 5 . 1 0 0 4 w w w . s g m - i n c . c o m Project Milestone: Da t e By : For Construction 15" 2"Ø Transport Line B R Y Y G W C.6.003 Title: OWTS Advantex Details Re v i s i o n # Dwg No. 12 6 6 O w l C r e e k R o a d Pi t k i n C o u n t y , C O Job No. Drawn by: Date: File: PE:QC: 2017-283.001 JB 10.10.2019 JWH OwlCreek-Details WC 11 8 W e s t S i x t h S t r e e t , S u i t e 2 0 0 Gl e n w o o d S p r i n g s , C O 8 1 6 0 1 97 0 . 9 4 5 . 1 0 0 4 w w w . s g m - i n c . c o m Project Milestone: Da t e By : For Construction m U m� Q N N O \ N m 0 ONSITE WASTEWATER TREATMENT GENERAL NOTES.• :. : / :. . ; •: 1.
