ENGINEERS & GEOLOGISTS May 2, 2000 Varnett Schorr Architects, Attn: Bud Schorr 303 Battery Street Seattle, WA 98121 Subject: Subsurface investigation and OWS Design, Proposed Aberdon Residence Lot 5, Eagle Pines Subdivision Pitkin County, Colorado Job No. 11837 Dear Mr. Schon, As requested, we have investigated subsurface conditions performed by our firm at the subject site and prepared an onsite wastewater system (OWS) design for the proposed residence. The subsurface investiga- tion was performed on October 12, 1999, and April 19,��0. The original OWS design was performed on October 28, 1999, and should be discarded to avoid confusion. SITE CONDITIONS The property is located in a residential area in Pitkin County, where OWS are required. The proposed drain field area has a slope of 2-3% to the north, and a moderate cover of native scrub, grasses and aspen trees. The residence will be served water by the local water district. PROPOSED CONSTRUCTION Awe -bedroom residence with a living area greater than 6000 square feet (SF) is proposed as presented on Figure 1. The OWS was based on 9 be and 2340 Gallons Per Day (GPD) using Aspen/Pitkin Envir- onmental Health Department (APEHD) loading of 130 gallons per day per person. The sewage loading with a peaking factor of 1.75 is 4095 GPD. This loading includes a garbage grinder and washing machines. SUBSURFACE CONDITIONS A subsurface investigation was performed by digging 7 percolation holes, 24 to 40 inches deep, and two profile pits at the locations indicated on Figure 1. Subsurface conditions in Profile -1 consisted of 6 inches of a sandy root zone, underlain by silty sand with gravel and large boulders to the maximum depth explored of 8 feet. Subsurface conditions in Profile -2 consisted of 1 foot of a sandy root zone, underlain by sandy, silty clay to 4 feet, underlain by sandy clay with gravel and boulders to the maximum depth explored of 8 feet. No ground water was encountered. Percolation tests indicate percolation rates of 5 to 30 minutes per inch (MPI). We are designing the drain field in the area of Profile -2, which has an average percolation rate of 23 MPI. Percolation data is presented in Table 1. RECOMMENDATIONS (, We recommend the installation of three septic tanks, a pump, and four chamber -type drain field beds installed at the locations presented on Figure 1. The OWS design is based on an average sewage load of 2340 GPD and it percolation rate of 23 MPI. Two 2500 -gallon single -compartment precast concrete septic 033 CASTLE ROCK 303.660.4358 DENVER 4501 Wadsworth Boulevard Wheat lidge, 3A63.9321 EVERGREEN 303.816.1455 303.463.9317 0 - Subsurface Investigation and OWS Design Job No. 11837 Page 2 tanks to be followed by one 1000 -gallon single -compartment pre -cast concrete septic tank with a pump in a Biotube vault are required, as indicated on Figure 3. The pump specifications are presented on Figure 4. A flow splitter basin is necessary to distribute effluent to the fields, as indicated on Figure 2. Each bed must have 3 rows of 16 chambers, for a total of 192 chambers. Vehicle movement over the drain field bed area during construction should be kept at a minimum to prevent compaction of the receiving soils. The bottom of the bed should be scarified with a pick, shovel, or backhoe bucket teeth prior to the addition of dispersal gravel. The surface of the field should be seeded after installation of the fields. 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 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 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. If there are questions or if we can be of further service, please call.
