The system was designed under our Job No. 11169-4, dated September 25,1999. The system includes the installation of a 2500 -gallon, two-compartment, precast concrete septic tank with a pump in a Biotube vault, and two chamber -beds. Each bed has four rows of 10 chambers for a total infiltrative area of 1240 square feet (SF). A distribution box was installed to distribute effluent throughout the beds. An OWS as -built drawing is included as Figure 1. The pump, alarm, and Biotube vault were in place at the time of our visit. The construction foreman, Walter Hooker, may activate the pumping system at his discretion. The components of the OWS were installed in conformance with our plans and specifications. If there are questions or if we may be of further service, please call. Sincerely, CHURCH and Edward O. Church, P EOC/trp/erb 000 0 0 CN REGssr 13172 �• f 2 copies sent conv to APEHD.

Any locattion where the residential water line comes witl- n 10 feet of the proposed sewer line a "lining" or "casing" of the water line is required. Pipe of Schecule 40 rating or better is required, ridged end caps of equivalent grade must be glued in a watertight fashion to the ends of the encasement. 2. All distribution boxes must 1 foot by 3 feet and require a baffle to disperse effluent at the inlet. 3. Septic tanks at Lots 2 and 4 must be upgraded from 2000 -gallon to 2500 -gallon two-compartment pre -cast concrete septic tanks with a pump in a BiotubeTM vault. 4. The septic tank at lot 6 needs to be upgraded from a 1500 -gallon to a 2000 -gallon two-compartment pre -cast concrete septic tank with BiotubeTM vault. 5. The average percolation rate for lot 4 is 31 minutes per inch (MPI), rather than 24 MPI. 6. A total of 99 chambcrs are proposed at tot 5; three beds, each having 3 rows of 11 chambers.

ENGINEERS & GEOLOGISTS September 25, 1999 Semrau Building Design 208 '/2 East Main Street Aspen, Colorado 81611 Subject: Subsurface Investigation and OWS Design, Proposed Triplex Lot 4, Pitkin Iron Pitkin County, Colorado Job No. 1.1169-4 Gentlemen: As requested, we: have evaluated subsurface conditions at the subject site and prepared an onsite wastewater system. (OWS) design for the proposed triplex. We investigated subsurface conditions on June 23, 1999. SITE CONDITIONS The property is located along Colorado State Highway 82 and borders the Roaring Fork River on the south side, as indicated on Figure 1. The site was originally a concrete batch plant and has layers of gravelly fill remaining onsite. The proposed drain field area is relatively flat. There is no vegetation. PROPOSED CONSTRUCTION A triplex with a total of six -bedrooms is proposed at the location presented on Figure 2. Each of the units will have an area of less than 2000 square feet (SF) as proposed. The OWS is sized on 6 bedrooms, which results in an average daily flow of 900 Gallons Per Day (GPD) using Aspen/Pitkin Environmental Health Department (APEI D) loading of 75 gallons per day per person. The sewage loading with a peaking factor of 1.75 is 1575 GPD. This loading includes a dishwasher, garbage grinder, and washing machine. The drain field is to be a minimum of 146 feet to all existing and proposed wells. SUBSURFACE CONDITIONS We performed a subsurface investigation by performing 3 and observing one; profile pit at the locations indicated c consisted of 6 feet of silty, sand and gravel fill with to the maximum depth explored of 8 feet. Percolation and indicated on Table 1. The average percolationto is the test pit. percolation tests, at depths of 29 to 35 inches, n Figure 2. Subsurface conditions in Profile 1 Amderlain by silty, sand and gravel with cobbles v4' om 24 to 40 minutes per inch (MPI), I. No free ground water was observed in DENVER 4501 Wadsworth Boulevard Wheat Ridge, CO 80033 CASTLE ROCK 303.660.4358 303.463.9317 Fax: 303.463.9321 EVERGREEN 303.816.1455 OWS Design Job No. 11169-4 Page 2 RECOMMENDATIONS We recommend the installation of one septic tank, an effluent pumping system, and four chamber -type drain field beds installed at the locations presented on Figure 2. The OWS design is based on an average sewage load of 1575 GPD and a percolation rate of 24 MPI. We recommend the installation of one 2000 -gallon, two-compartment pre -cast concrete septic tank with an effluent pump in an Orenco Biotube'm vault, as indicated on Figure 4. With basement plumbing and the relatively flat sites, the septic tanks will be installed at depths of 8 to 10 feet. Risers must be installed to bring all access lids to the ground surface. A pump is required to accommodate basement plumbing and to distribute the effluent to the trenches to increase the performance of the field. We recommend a distribution box to distribute effluent to the fields. The pump must have a minimum flow rate of 25 gallons per minute and at a total dynamic head of 14.0 feet. There should be an approximate 250 -gallon dose per cycle. Pump details are presented on the pump curve. We recommend the installation of two beds, each bed with 4 rows of 10 chambers, as indicated on Figures 2 and 3. If additional bedrooms are anticipated in unfinished areas, we recommend sizing of the OWS for the build -out number of bedrooms. The installation of an OWS for the build -out number of bedrooms is most economical in the long term. Equipment movement over the drain field area during construction should be kept at a minimum to reduce compaction of the receiving soils. We recommend the bottom of the trenches be scarified with a pick, shovel, or backhoe bucket teeth prior to the addition of dispersal gravel. We recommend the surface of the field be seeded after installation of the field area. We recommend using a native seed mix available at seed stores. These mixes do not require irrigation and develop a growth 10 to 15 inches high. No automatic sprinkler system should be installed over the fields. OPERATION AND MAINTENANCE The owner must realize an OWS is different from public sewer service. The owner must be aware of, and assume responsibility for, continued maintenance of the system. In the absence of a monitoring program, we recommend the septic tank be pumped every two years. Effluent filter and screened vaults, as applicable, are to be cleaned during pumping. There are daily considerations such as not putting plastic or other nonbiodegradable materials into the septic system. Garbage disposal use should be minimized. The backwash of a water softener may be harmful to the OWS. A separate drywell should be constructed for the backwash waste, if a softener is installed. Chemically treated water from a swimming pool or spas should not be introduced to the OWS. LIMITATIONS An OWS design should be installed by a contractor who is experienced in its installation. Our investigation, layout, design and recommendations are based on data submitted. If subsurface conditions considerably different from those described in this report are encountered, we should be notified to evaluate the effect on the proposed OWS. If the health department makes modifications to this design, we should be contacted to evaluate the impact on the performance of the OWS. The county and our firm must be contacted upon completion of the OWS 0 OWS Design Job No. 11169-4 Page 3 All construction is to be in accordance with the ISDS regulations. Pipe type and size, burial requirements, septic tank construction, and other specifications, which are not depicted in our report, are to conform to the requirements of the ISDS regulations. The installer of the system is to have demonstrated knowledge of the APEHD ISDS regulations and requirements. CHURCH & Associates Inc.. _ C E, k Uj 13172 Edward O.
