The property is located outside of Aspen Colorado, in an area where OWS and wells are necessary. SITE CONDITIONS Multiple structures exist on the subject site. The Historic Homestead and the Historic Cabin utilize an OWS that has an upgraded septic tank. The existing ell servin the structures _is to be abandoned. A new drain field is being proposed. The historic homestead has 3 -bedrooms and the historic cabin has 1 -bedroom. The proposed drain field area is relatively flat, and vegetation consists of a moderate cove -"of grasses. Water will be provided by the onsite well, as indicated. SUBSURFACE The subsurface was investigated by digging one profile pit and three percolation holes, at the locations indicated on the plans. The materials in the profile hole consisted of 6 -inches of a sandy root zone, underlain by sand with sparse gravel and cobbles to the maximum depth explored of 8 feet. Groundwater or bedrock was not encountered. An average percolation rate of 17 MPI wi4 be'uslin the design. DESIGN SPECIFICATIONS The OWS design is based on 4 total bedrooms and an average sewage load of 600 GPD. The installation must include the existing 1250 -gallon, two-compartment concrete septic tank with an effluent .fittgr on the outlet followed* 4 rav-elf s chamber trenches. Each trench must have 14 _ �': _ g- `Quick -4' chambers for a total are of 553 F. A concrete stn`bufion box with a baffle must be used Subsurface Investigation and OWS Design Project No. 1398 5/27/08 Page 2 to distribute effluent. Construction must be according to the county ISDS regulations, the septic permit provided by Pitkin County Environmental Health Department, and this design. OPERATION INFORMATION AND MAINTENANCE The surface of the drain field should be seeded upon completion. Vegetation is an important factor in drain field performance. Erosion control should be practiced prior to and during re -vegetation. Geo - fabrics or plastics should not be used over the drain field. Livestock should not graze on the drain field. Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWS. For Example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a drain field. The homeowner should pump the septic tank every two years and clean the effluent filter as needed. Garbage disposal use should be minimized, and non -biodegradable materials should not be placed into the OWS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWS. No hazardous wastes should be directed into the OWS. Mechanical room drains should not discharge into the OWS. The OWS is engineered for domestic waste only. ADDITIONAL CONSTRUCTION NOTES If design includes a pump, air release valves and weep holes should be installed to allow pump lines to drain to minimize risk of freezing. Excavation equipment must not drive in excavation of drain field due to the potential to compact soil. Extensions should be placed on all septic tank components to allow access to them from existing grade. Precast concrete tanks and distribution boxes should be used, unless plastic or fiberglass is required. Access to all tank compartments and distribution devices is optimal. INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC, and the county must view the OWS during construction. The OWS observation should be performed before backfill, after placement of chambers and distribution pipes. 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 OWS construction must be according to the county regulations. Requirements not specified in this report must follow county regulations. The installer should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Sincerely, .._�..�aestions.
