The property is located outside of Aspen, in an area where OWTSs are necessary. Previous design documents dated November 1, 2015 must be discarded and replaced with documents dated March 25, 2016. The legal descr ption of the 5.68 -acre property is listed on the Pitkin County Assessor's Webpage as Section: 3 Township: 10 Range: 85 A PARCEL IN SW4NW4 & NW4SW4 SEC 33-10-85 DESC BY M/B SITE CONDITIONS A single-family residence presently exists on the property and is utilizing an existing OWTS. A remodel is proposed which will result in a total of 7 -bedrooms and greater than 6000 square feet of living area. The extent of the remodel encroaches on the required 20 -foot setback to the soil treatment area (STA). The original OWTS was documented by Pitkin County Individual Sewage Disposal System (ISDS) Permit 06033 and was sized to accommodate 5 bedrooms. This system included a 2500 -gallon single compartment septic tank followed by a 1000 -gallon septic tank with a pump in the second compartment and a 120' x 59' pipe and gravel STA. Pitkin County O\NTS Construction Permit 001.2014.pow2 documents a modification to the OWTS in 2014 that would accommodate a total of 8 -bedrooms with greater than 6000 square feet of total living area in the residence. The existing 2500 -gallon, single -compartment and existing 1000 -gallon, two-compartment septic tank remained in use. A pumping system in the second compartment of the 1000 -gallon tank remained in use due to the depth of these septic tanks. A new 1000 -gallon, three -compartment Valley Precast concrete septic tank with a recirculation pump in the second compartment and discharge pump in the third compartment and two AdvanTexT"" AX -20 pods were installed. Effluent was pumped to the existing STA. This existing STA will be abandoned and replaced with a new STA, outlined in this design. The residence is served potable water provided by Buttermilk Metro District. The proposed STA will be at least 25 -feet from any water line. Page 2 SUBSURFACE The subsurface was investigated on October 9, 2015 by digging two soil profile test pit excavations (Test Pits). Both Test Pits were dug in the area of the existing STA, which is not currently in use. A visual and tactile analysis of the soil was completed by Carla Ostberg at the time of excavation.' The materials encountered in Test Pit #1 consisted of medium brown, moist, topsoil to 18 -inches, underlain by the existing STA, consisting of separation fabric, distribution piping and gravel to 30 -inches, underlain by reddish brown clay loam with a blocky structure shape, moderate structure grade, and friable consistence to a maximum depth explored of 8.0 -feet. Cobbles 4 to 8 -inches in diameter were present. No bedrock or groundwater was encountered. The soil sample taken below 30 -inches formed a ball and a ribbon 1 to 2 -inches in length before breaking, and had both a gritty and smooth texture. The materials encountered in Test Pit #2 were consistent with those in Test Pit #1. A maximum depth of 8.0 -feet was explored. No bedrock or groundwater was encountered. ISDS Permit 06033 documents a percolation rate of 240 minutes per inch (MPI). Our findings are not consistent with this documented percolation rate. A long term acceptance rate (LTAR) of 0.6 gallons per square foot will be used to design the OWTS, in accordance with Pitkin County OWTS Regulation, Table 6.28-7, Soil Type 3, utilizing AdvanTex® technologies which are able to achieve Treatment Level 3 (TI -3). DESIGN SPECIFICATIONS The OWTS design is based on 7 -bedrooms having greater than 6000 square feet of living area. A design flow of 1400 GPD will be used. The existing septic tank and advanced treatment infrastructure documented in OWTS Construction Permit 001.2014.pow2 will remain. Design Calculations: 7 bedrooms x 100 gallons/person/day x 2 people/bedroom = 1400 gallons/day Septic Tank Capacity = 1400 gallons/day x 48 hour retention time = 2800 gallons minimum EXISTING: 2500 gallon + 1000 gallon + 1500 gallon STA Calculations = 1400 gallons/day / 0.60 SF/gallon (Clay Loam Soil Type 3, TL3) = 2333 SF Pressure Dosed Beds 2333 SF x 1.0 = 2333 SF 2333 SF / 12 SF/chamber = minimum 195 `Quick 4' Infiltrator® chambers The existing PF5005 Orenco® pumpz should be replaced with a PF3005 Orenco® pump in the third compartment of the Valley Precast 1000 -gallon, three -compartment septic tank. The PF3005 will achieve optimal performance for this pump curve. Effluent will be pumped via a 2 -inch diameter pump line to an Automatic Distributing Valve (ADV), Model 6404, to be installed at the high point. The 2 -inch diameter pump line must have a minimum grade of 1 % to attain proper drain back into the septic tank after each dose. The existing STA must be removed in the area of the new beds. The remaining existing STA may be abandoned in place and will no longer be utilized. ' Carla Ostberg holds a Certificate of Attendance and Examination from the CPOW Visual and Tactile Evaluation of Soils Training. 2 This existing pump model must be verified. If sizing is different than documented, this office must be contacted. Page 3 The ADV must be accessible from grade. Effluent will be pressure distributed to four gravelless chamber beds; three beds with 4 rows of 12 `Quick 4' Infiltrator® chambers in each row and one bed with 4 rows of 13 'Quick 4' Infiltrator® chambers for a total of 196 total chambers. There must be at least 6 -feet of undisturbed soil between each bed. Each bed will be connected with a 1.5 -inch diameter level manifold. Effluent will be pressure dosed to 1.5 -inch diameter laterals, which must be hung with zip ties from the underside of the chambers. Laterals will have 1/8 -inch diameter orifices facing up, with the exception of the first and last orifices facing down for drainage. The orifices must be placed 3 -feet on center. Each lateral must end in a 90 degree ell facing up with a ball valve for flushing. Valves may be placed in a valve box, accessible from grade. Inspection ports must be placed at the beginning and end of each trench. Ports may be cut to grade and covered with a valve box for access. Valley Precast holds the current annual service contract for the AdvanTexTM system. This contract is required per manufacturer specifications and Pitkin County OWTS Regulation. The component manufacturers are typical of applications used by contractors and engineers in this area. Alternatives may be considered or recommended by contacting our office. Construction must be according to Pitk n County Onsite Wastewater Treatment System Regulations, the OWTS Construction Permit provided by Pitkin County Environmental Health Department, and this design. REVEGETATION REQUIREMENTS An adequate layer of good quality topsoil capable of supporting revegetation shall be placed over the entire disturbed area of the OWTS installation. A mixture of native grass seed that has good soil stabilizing characteristics (but without taproots), provides a maximum transpiration rate, and competes well with successional species. No trees or shrubs, or any vegetation requiring regular irritation shall be placed over the STA. Until vegetation is reestablished, erosion and sediment control measures shall be implemented and maintained on site. The owner of the OWTS shall be responsible for maintaining proper vegetation cover. OPERATION INFORMATION AND MAINTENANCE The property owner shall be responsible for the operation and maintenance of each OWTS servicing the property. The property owner is responsible for maintaining service contracts for manufactured units, alternating STAs, and any other components needing maintenance. Geo -fabrics or plastics should not be used over the STA. No heavy equipment, machinery, or materials should be placed on backfilled STA. Livestock should not graze on the STA. Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWTS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a STA. If an effluent filter or screen has been installed in the OWTS, we recommend this filter or screen be cleaned annually, or as needed. If the OWTS consists of a pressurized pump system, we recommend the laterals be flushed annually, or as needed. The homeowner should pump the septic tank every two years, or as needed gauged by measurement of solids in the tank. Garbage disposal use should be minimized, and non -biodegradable materials should not be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste only. Page 4 ADDITIONAL CONSTRUCTION NOTES If design includes a pump, weep holes must be installed to allow pump lines to drain to minimize risk of freezing. The pump shall have an audible and visual alarm notification in the event of excessively high water conditions and shall be connected to a control breaker separate from the high water alarm breaker and from any other control system circuits. The pump system shall have a switch so the pump can be manually operated. Excavation equipment must not drive in excavation of the STA due to the potential to compact soil. Extensions should be placed on all septic tank components to allow access to them from existing grade. Backfill over the STA must be uniform and granular with no material greater than minus 3 -inch. INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC must view the OWTS during construction. The OWTS observation should be performed before backfill, after placement of OWTS components. Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. ALL SERVICE septic, LLC should be notified 48 hours in advance to observe the installation. LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions described in report, ALL SERVICE septic, LLC should be notified. All OWTS construction must be according to the county regulations. Requirements not specified in this report must follow applicable county regulations. The installer should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Please call with questions.

Using a Pump Curve A pump curve helps you Bete mine the best pump for your system. Pump curves show the relationship between flow (gpm or Usec) 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 — the value, measured in gpm, expressed by the first two numerals in an Orenco pump nomenclature. The graphs in this section show optimal pump operation ranges with a solid line. Flow flow rates outside of these ranges are shown with a dashed line.

These zones can be segments of sand filter manifolds, drainfields, or other effluent distribution systems. Distributing valve assemblies can substantially simplify the design and installation of a distribution sys- tem and reduce installation costs. This is particularly true where a distributing valve assem- bly is used instead of multiple pumps and/or electrically operated valves. Additionally, a reduction in long term operation and maintenance costs is realized due to a reduced size and/or number of pumps. More even distribution can be achieved on sloping sites by zoning laterals at equal elevations. This eliminates drainback to lower lines and the unequal distrib- ution of effluent that occurs at the beginning of a cycle. Valve Operation The valve itself has only a few moving parts, requires no electricity, and alternates automati- cally each cycle. Refer to Figure l for the following valve operation description. The flow of the incoming effluent forces the rubber flap disk 0 to seat against the valve bottom 0. The opening 0 in the rubber flap disk aligns with an opening in the valve bottom to allow flow to only one valve outlet. The stem 0 houses a stainless steel spring which pushes the rubber flap disk away from the valve bottom after the flow of effluent stops. The stem acts as a cam follower and rotates the rubber flap disk as the stem is raised and lowered through the cam 0. The force from the flow of effluent pushes the stem down through the cam and the stainless steel spring pushes the stem back up through the cam when the flow of effluent stops. Each linear motion of the stem allows the rubber flap disk to rotate half the distance necessary to reach the next outlet. When there is no flow, the rubber flap disk is in the "up" position and is not seated against the valve bottom. * O � © 1 r �c Inlet j 0 j Q 0 I Cr � I .Q 1? — —' �O� Outlets Figure 1: 6000 Series Valve 1-800-348-9843 NTP -VA -1 Rev. 11, ©11/03 Orenco Systemsr, Inc. Page 1 of 6 Figure 2: Orenco Distributing Valve Assembly (6000 Series Valve) The Distributing Valve Assembly The Orenco Automatic Distributing Valve Assembly combines the distributing valve itself and sever- al other components to give a complete preassembled unit that is easy to install, monitor, and main- tain. Figure 2 shows a complete assembly. Because distributing valves with several outlets can be difficult to line up and glue together in the field, the discharge lines in the assemblies are glued in place at Orenco. The unions (1) allow removal and maintenance of the valve. The clear PVC pipe sections (2) give a visual check of which discharge line is being pressurized. The inlet ball valve (3) allows a quick, simple method to test for proper valve cycling. The ball valve also stops the flow of effluent in case the pump is activated unexpectedly during maintenance or inspection. Check valves may be necessary on the discharge lines. Use of check valves is discussed in the valve positioning section. Valve Assembly Hydraulics Liquid flowing through the valve assembly must pass through fairly small openings and make several changes in direction. Because of this, headlosses through the valve assembly are fairly high. Table 1 gives the headloss equations for several different assemblies and Figure 3 shows the graphical repre- sentations of these equations. Orenco recommends that high -head turbine pumps be used to pressur- ize the valve assemblies to ensure enough head is available for proper system operation. High -head turbine pumps are; also recommended because the use of a distributing valve usually requires more frequent pump cycling. The high -head turbine pumps are designed for high cycling systems and will outlast conventional effluent pumps by a factor of 10 or more in a high cycling mode. Furthermore, the high -head turbine pump intake is 12 inches or more above the bottom of the pump and tends to prevent any settled solids from being pumped into the distribution valve and obstructing its opera- tion. A minimum flow rate through the distributing valve is required to ensure proper seating of the ribber flap disk. Minimum flow rates for the various models are given in Table 1.

However, because of the mechanical movements of the valve, it is necessary to take steps to prevent solids from reaching the distributing valve that may impede the operation of the valve. Orenco Biotube' Pump Vaults — when properly sized and installed provide the necessary protection to prevent valve malfunction. The Biotube' pump vault accepts effluent only from the clear zone between a tank's scum and sludge layers and then filters this effluent through a very large surface area screen cartridge. Without this protection in effluent systems, the valve has very little chance of reliable long-term operation. NTP -VA -1 Rev. 12, ®11/03 Orenco Systema°, Inc. Page 3 of 6 Valve Positioning The physical position of the valve in relation to the pump and the discharge point is very important for proper valve operation. The most reliable operation occurs when the valve is placed at the high point in the system and as close to the pump as possible. The transport line between the pump and valve should be kept full if possible. If the line is empty at the beginning of each cycle, pockets of air during filling can cause random rotation of the valve. The valve is particularly vulnerable to this erratic rotation with empty lines that are long and not laid at a constant grade. An ideal valve loca- tion is shown in Figure 4. If the final discharge point is more than about 2 feet above the valve and the system does not drain back into the dosing tank, check valves should be installed on the lines immediately following the valve and a pressure release hole or line should be installed just prior to the valve. This pressure release hole or line can go into a return line to the dosing tank or to a "minidrainfield" near the valve. In order for the valve to rotate reliably, no more than about 2 feet of head should remain against the valve to allow the rubber flap disk to return to its up position. In many cases, it may take from one minute to several minutes for the pressure in the valve to be lowered enough for proper rotation to occur. Special care should be taken when installing systems controlled by programmable timers to ensure cycling does not occur too rapidly. Figure 5 illustrates a valve assembly using check valves. Pumping downhil [ to the valve should be avoided unless the transport line is very short and the ele- vation between the discharge line out of the tank and the valve is less than about 2 feet. If the valve is located many feet below the dosing tank, random cycling may occur while the transport line drains through the valve at the end of the cycle. A pressure sustaining valve located just before the distrib- uting valve may overcome this problem in some instances. Transport Line Dosing Tank Figure 4: Ideal valve location Distributing Valve Assembly Discharge Laterals NTP -VA -1 Rev. 12, ©11/03 Orenco Systems Inc. Page 4 of 6 System Startup Refer to the Hydrotek Valve booklet that is provided with the distributing valve assembly for the sequencing of the valve outlets. The transport line should always be flushed with clean water before installing the valve. Any sand, gravel, or other foreign objects that may have been in the pipe during installation can easily become lodged in the distributing valve, causing malfunction. With the pump running, alternately close and open the ball valve on the distributing valve assembly to check proper rotation of the valve. (Note: If check valves are used on the lines after the distribut- ing valve, the pump may need to be turned on and off to allow the pressure to be released from the valve.) If visual operation of which zone is operating is not possible, watch the clear pipe on each line for indication of which zone is operating. Figure 5: Valve assembly below final discharge point Maintenance Annually check for proper operation by following procedures listed in the Hydrotek Valve booklet and system startup procedures listed above. Troubleshooting 1. PROBLEM: Valve does not change or cycle to next zone or outlet CAUSE: The stem and disk assembly is not rotating when water flow is turned off and then back on. SOLUTION 1: Ensure that there is no debris inside the cam. Clean and carefully reinstall the cam. SOLUTION 2: If fewer than the maximum number of outlets are being used, check the installation of the cam. Ensure that the stem and disk assembly is not being held down by an improperly installed cam. Refer to the cam replacement instructions. NTP -VA -1 Rev. 11, © 11/03 Orenco Systems', Inc. Page 5 of 6 SOLUTION 3: Remove the valve top and check for proper movement of stem and disk assembly. Check for and remove any debris or foreign objects that may jam or retard the movement of the disk. SOLUTION 4: Check for freedom of movement of stem and disk assembly up and down over the center pin in bottom of valve. Scale deposits may build up on the pin and hold stem and disk assembly down. Clean pin and again check for freedom of movement. SOLUTION 5: Be sure that all operating outlets are not capped and that the flow to operating zones is not restricted in any manner. This would cause pressure to build up in the valve and lock the stem and disk assembly in the down position. SOLUTION 6: The backflow of water from uphill lines may be preventing the valve from cycling properly. This can happen when the valve is placed too far below an elevated line. If the valve cannot be placed close to the high point of the system, a check valve should be installed near the valve in the outlet line that runs uphill from the valve and a drain line installed just prior to the valve to relieve the pressure. 2. PROBLEM: eater comes out of all the valve outlets CAUSE: Stem and disk assembly not seating properly on valve outlet. SOLUTION 1: Check for sufficient water flow. A minimum flow rate is required to properly seat the disk as shown in Table 1. SOLUTION 2: Remove the valve top and check the inside walls to ensure that nothing is interfering with the up and down movement of the stem and disk assembly inside the valve. SOLUTION 3: Make sure that the operating outlets are not capped and that the flow to the operat- ing zones are not restricted in any manner. 3. PROBLEM: Valve skips outlets or zones CAUSE: Pumping into an empty transport line — especially downhill — may cause the valve to skip outlets from pockets of air allowing the rubber flap disk to raise during a c:Ycle. SOLUTION 1: Keep the transport line full. SOLUTION 2: If the line must remain empty between cycles, use a larger diameter transport line laid at a constant grade to prevent air pockets from forming. CAUSE: The stem and disk assembly is being advanced past the desired outlet. SOLUTION 1: Ensure that the correct cam for the desired number of zones is installed and that the outlet lines are installed to the correct outlet ports of the valve as indicated by the zone numbers on the top of the cam.

Page 6 of 6 Distributing Valves Applications Automatic Distributing Valve Assemblies are used to pressurize multiple zone distribution systems including textile filters, sand filters and drainfields. cle Bottom View Specifications Materials of Construction All Fittings: Unions: Ball Valve: Clear Pipe: V4XXX Distributing Valves: VWX Distributing Valves: Side View Submittal Data Sheet General Oreneo systems• Incorporated 1 -SOU -348-9W Orenco's Automatic Distributing Valve Assemblies are mechanically operated and sequentially redirect the pump's flow to multiple zones or cells in a distribution field. Valve actuation is accomplished by a combination of pressure and flow. Automatic Distributing Valve Assemblies allow the use of smaller horsepower pumps on large sand filters and drainfields. For example, a large community drainfield requiring 300 gpm can use a six -line Valve Assembly to reduce the pump flow rate requirement to only 50 gpm. Orenco only warrants Automatic Distributing Valves when used in conjunction with High -Head Effluent Pumps with Biotube® Pump Vaults to provide pressure and flow requirements, and to prevent debris from fouling valve operation. An inlet ball valve and a section of clear pipe and union for each outlet are provided for a complete assembly that is easy to maintain and monitor. Ideal valve location is at the high point in the system. Refer to Automatic Distributing Valve Assemblies (NTP -VA -1) for more information.
