Drawer 309 FN�jR� IN CO�NTY Glenwood Springs, Colorado 81602 NT,gt NFq�TH Subject: Subsurface Investigation and Revised OWS Design, Proposed Senn Residence 133 Chair Mountain Drive Lot 35, Crystal River Park Pitkin County, Colorado Job No. 13787W Mr. Senn, As requested, we have investigated subsurface conditions and designed a revised onsite wastewater system (OWS) for the proposed residence. The revisions are based on the inclusion of a "bonus" room into the total square footage of the residence. The additional living area requires an increase in the average daily flow calculations from our original report, dated August 24, 2001. Our original design should be discarded to avoid confusion. The subsurface investigation was performed on August 22, 2001. SITE CONDITIONS The property is in a rural residential area in Pitkin County, where OWS are required. The proposed drain field area has an 11% slope to the east and a thick cover of native grasses and a moderate cover of aspen trees. The site will be served by the local water district. PROPOSED CONSTRUCTION A three-bedroom residence with a living area of 2304 square feet (SF) is proposed as presented on Figure 1. The OWS was sized based on 3 bedrooms and 600 Gallons Per Day (GPD) using Aspen/Pitkin Environ- mental Health Department (APEHD) loading of 100 gallons per day per person. The sewage loading with a peaking factor of 1.75 is 1050 GPD. This loading includes washing machines and garbage grinders. SUBSURFACE CONDITIONS A subsurface investigation was performed by digging six percolation holes, 18 to 198 inches deep, and one profile pit at the locations indicated on Figure 1. Subsurface materials in the profile pit consisted of six inches of topsoil, underlain by silty sand with gravel to 14 feet, underlain by silty sand with gravel and cobbles to the maximum depth explored of 16 feet. No ground water was encountered. Percolation tests indicate percolation rates of 6 to 13 minutes per inch (MPI). The average percolation rate is 9 MPI. Percolation data is presented in Table 1. RECOMMENDATIONS We have prepared an OWS design, which includes a septic tank and drywell for the site. The OWS design is based on a peak sewage load of 1050 GPD and a percolation rate of 9 MPI. The installation must include DENVER 4501 Wadsworth Boulevard Wheat Ridge, CO 80033 CASTLE ROCK 303.660.4358 303.463.9317 Fax: 303.463.9321 EVERGREEN 303.816.1455 LOVELAND 970.663.2124 WESTERN SLOPE 970.948.5803 Subsurface'-stigation and Revised OWS Design Job No. 13787, 4105/02 Page 2 one 1500 -gallon, two-compartment, pre -cast concrete septic tank with an effluent filter on the outlet and a 7 -foot wide by 15 -foot long by 12 -foot deep drywell. The OWS should be constructed similar to Figures 1 through 3. Vehicle movement over the drywell area during construction should be kept at a minimum to minimize compaction of the receiving soils. The bottom of the drywell should be scarified with a pick, shovel, or backhoe bucket teeth prior to the addition of dispersal gravel. The surface of the drywell should be seeded after installation of the field. A native seed mix should be sown on top of the dry�vell field to revegetate the surface. 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, the septic tank should 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 nonbi- odegradable 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. T LMTTATIONS 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 o � Awa mij/ f further service, please call.
