ENGINEERS & GEOLOGISTS April 16, 2004 Braebum Builders LTD Attn: Doug Boyles P.O Box 1247 Carbondale, Colorado 81623 Subject: Revised OWS Design, Proposed Hartwig Residence Parcel 1, Hardy Hills Garfield County, Colorado Job No. 16303 Mr. Boyles, As requested, we have prepared a revised onsite wastewater system (OWS) design for the proposed residence. The revisions are based on a decrease in the number of bedrooms from our original design, dated March 19, 2004. All previous designs should be discarded to avoid confusion. The subsurface investigation was performed on March 5, 2004. SITE CONDITIONS The lot is located in a rural residential area in Garfield County, Colorado, where OWS are required. The proposed drain field area has a 10% slope to the south-southeast. There is a moderate cover of native grasses, sagebrush, and evergreen trees. Water is provided to the residence by a well located 250+ feet south of the proposed drain field area. PROPOSED CONSTRUCTION A four-bedroom residence is proposed as indicated on Figure 1. In accordance with the Individual Sewage Disposal System (ISDS) regulations, the average sewage loading for a four-bedroom residence is 600 Gallons Per Day (GPD) and 900 GPD with a 1.5 peaking factor. This loading includes a dishwasher, gar- bage grinder, and washing machine. If additional bedrooms in unfinished areas are possible, it is suggested the OWS be constructed to serve the added loading. The installation of an engineered OWS to serve future build -out can be cost effective. SUBSURFACE CONDITIONS The subsurface investigation was performed by digging three percolation holes, 27 to 34 inches deep, and one test pit at the locations indicated on Figure 2. Subsurface materials in the test pit consisted of 1 foot of clayey sand underlain by silty, sandy clay with scattered cobbles to the maximum depth explored of 8.5 feet. No ground water or bedrock was encountered. Percolation tests indicate percolation rates of 23 to 53 minutes per inch (MPI). The average percolation rate is 33 MPI. Percolation data is presented in Table 1.

The OWS design is based on an average sewage load of 600 GPD and a percolation rate of 33 MPI. The installation must include a 1500 -gallon, two-compartment, concrete septic tank and four chamber -trenches. Each trench must have one row of nine chambers for a total of 36 chambers and 558 ft2 of infiltrative area. The trenches may be modified to conform to topography and to preserve as much vegetation as possible. Installation of an effluent filter on the outlet of the septic tank is optional and would serve to increase drain field longevity by minimizing the flow of solids to the drain field. A flow splitter basin, or equivalent is required to distribute effluent to the field. Movement over the drain field trench during construction should be kept at a minimum to minimize compaction of the receiving soils. The bottom of each trench must be scarified with a pick, shovel, or backhoe bucket teeth prior to the addition of chambers. The surface of the drain field should be seeded after installation of the system. A native seed mix from the area available at seed stores should be used. These mixes do not require irrigation and develop a growth 10 to 15 inches high. No automatic sprinkler system should be installed over the field. OPERATION AND MAINTENANCE The owner must realize an OWS is different from public sewer service and must assume the responsibility for maintenance of the OWS. The system is relatively maintenance free, but the owner must have the septic tanks pumped. In the absence of a monitoring program, the septic tank should be pumped and the effluent filter cleaned every two years. There are daily considerations, such as not putting plastic or other nonbiode- gradable material into the OWS. Water use must be monitored so toilets are not allowed to run when seals malfunction. To illustrate the point, a running toilet can consume in excess of 1000 GPD. A loading of 1000 GPD could flood and irreparably harm the OWS. The loading from 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 requires installation by a licensed contractor. Our investigation, layout, design and recom- mendations are based on data submitted. If conditions 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 modifies this design, we should be contacted to evaluate the impact on the performance 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 ISDS regulations and requirements. If there are questions or if we can be of further service, please call.
