As requested, we visited the site and preuared an Onsite Wastewater System (OWS) design for the home. Subsurface conditions were investi- gated by Nelson Environmental & Wastewater Solutions. Ltd. SITE CONDITIONS - The home is a 3 bedroom residence on a <1"-_acre 'act as presented on Fig. 1. The home is located in an area where OWS and wells are used. There is sewer service in the area, but the property is not located in a district, and the Mid-Vallev Sanitation District decided not to include the property in the district. EXISTING CONSTRUCTION - A 2000 sauare foot (SF) three bedroom home exists as indicated on Fig. 1. There is plumbing in the basement which resulted in a deer tank and seenaae nit. The seen_aa_e pit is failing with sewage backing into the basement. The sewage load for a 3 bedroom home is 450 gallons ner day (GPD) at 75 GPD per patron, assuming 2 people per bedroom. Eagle County re- quires a neakina factor of 1.5 which includes a garbage grinder and washing machines. The around surface slopes aently to the north. The proposed field is located in a corral area. The slope at the drain field is 2% to the north. T ere is a cover of native grasses. There are rounded boulders at the surface. SUBSURFACE CONDITIONS - The site is located in a broad valley. The valley has alluvial origins. Subsurface conditions were exposed in a test pit at the proposed field and indicated 11 feet of gravelly_ and silty_ rou sand with cobbles and boulders. Gravel and cobbles to 12 inches in iameter were observed. No gnd water observed to a depth of 11 feet. Percolation tests were performed by Nelson indicate percolation rates ranging from 16 to 18 minutes per inch (MP1), with an average percolation rate >f17 MPI RECOMMENDATIONS - The results of our site visit indicates an OWS can be installed as presented on Fig. 1. The OWS design is based on a sewage load of 450 GPD and an average percolation rate of'17 MPI. The 925 East 17th Avenue • Denver, Colorado 80218-1407 P.O.

We recommend upsiina the septic tank by 250 gallons and installing an Orenco screened�ault pump sv /, as indicated on Fia. 2. Based on a sewage load' a of 675 GPD, 843 gallons of septic tank capacity is required for 3 our retentio With the pump installed a minimum of 12 inches of of the base of the tank, the 843 gallons of capacity will be stored in a 1250 aallon tank. An alternative is a 1000 aallon two compartment tank and a separate 500 gallon lift station. With the use of Ichambersl0 a reduction of 40% in area is allowed which results in 334 SF of -trenches. Based on the variable and coarse materials, we recomme a is ina 2 feet of filter material below the dispersal laver/chambers. We understand the installer would like to be "cham- ber" units such as,-- Ifiltrat�r We recommend the overexcavated 2 feet below the planned bottom of Infiltrators with minus 3 inch onsite material. We recommend the installation of two trenches each a minimum �W of. 10..Infiltrators long, 63 feet in lenath. Distribution pipe s ould be "suspender,, orom e nnamber units fcr distribution throughout the trenches. The trenches should be constructed similar to the details U presented on Fig. 1. We do not recommend the reduction if a bed field configuration is selected. , If additional bedrooms are anticipated, w��recommend the OWS be sized for the number of bedrooms the house could be sold for. The owner must realize an OWS is different from a public sewer system. The owner must be aware of and assume responsibility for maintenance of the OWS. We recommend the septic tank be pumped at every 2years. There are daily considerations such as not putting plastic or other nonbiodegradable materials down the system. Water use must be moni- tored so toilets are not allowed to run when seals malfunction. To illustrate the point, it should be noted a running toilet will use in excess of 1,000 GPD if allowed to run. As the OWS is designed for 450 GPD, an excess 1000 gallon loading will flood and harm the trenches. We caution you against installation of a water softener. The hydraulic loading from the acwash of a water softener is detrimental to OWS and a separate drywell should be constructed for the backwash waste. LIMITATIONS - Our layout, design and recommendations are based on data submitted. If subsurface conditions different from those described in this report are encountered, we should be called to observe the sub- surface conditions. If proposed construction is changed, we should be notified to evaluate the effect of the changes on the proposed system. If there are any E. O. CHURCH, Edward O.

Mr. Walsh's property is currently outside of the District's boundaries but the District's sewer line does run in front of his property. However, there was a concern the District's sewer line was too shallow on Mr. Walsh's side of the street for Mr. Walsh's waste to gravity flow into the line. The Board agreed that if Mr. Walsh could connect to the District's system on his side of the street, and if, his waste would gravity flow into the lines, then he would need to connect to the District's system. However, if the District's line was too shallow on his side of the street and he would have to connect on the other side of the street to be low enough to allow for gravity flow, then the Board would not require him to connect to the District system. The Board did not want Mr. Walsh to have to cut the road and obtain a road cut permit. Today, Bryan from Schmueser Gordon Meyer, Inc., the District's engineers, met with Mr. Walsh to determine if it was feasible for him to connect to the District's system on his side of the street. Bryan determined that the District's sewer line was too shallow on Mr. Walsh's side of the street for his waste to gravity flow into the system. Therefore, Mid Valley Metropolitan District is not requiring Mr. Walsh to connect to its system and Eagle County should proceed as necessary. Thank you for your cooperation. If you have any questions, please don't hesitate to call. Office hours are Tuesday through Friday, 9 a.m. - 3 p.m. Or you may contact the District's engineer, Louis Meyer, at (970) 945-1004.

M. and numbered as 0395 Valley Road, Eagle County, Colorado, Dear James and Adair, This company has conducted an inspection of the referenced property for the purpose of evaluating the possible replacement of the on -site wastewater disposal system serving the existing dwellings constructed in about 1970. It is reported that septic tank effluent was backing up from the seepage pit and it was clogged. While there are some central collection sewer lines in the area provided by the Mid -Valley Sanitation District, this particular property is not within the district boundaries, and the Sanitation District Board, at its meeting last week, decided it was not necessary to serve the property. As a result of these conditions and as requested, Nelson Environmental and Wastewater Solutions, Ltd., performed a soils study and percolation tests for a replacement septic system for the structure. We conducted this study in accordance with Section 4 of the Eagle County Individual Sewage Disposal System Regulation. We have based our recommendations on the subsurface conditions encountered. We will furnish this letter to the Eagle County Environmental Health Department as soon as possible in order for you to obtain a permit to reconstruct this individual sewage system. Existing Construction and Building Site: The building was originally constructed in the late 1960's or early 1970's. The residential property is on a tract of approximately 1 acre. The existing residence is a single-family house with a total of three bedrooms, two bathrooms, and a finished basement. The living area of the residence is approximately 2000 square feet The site is a lot in the Summit Vista area of El Jebel. The topography is gently sloping toward Highway 82, to the Northwest at grades of less than 5%. The area of the proposed replacement absorption filed is_in--a-pasture-area toward--the-rearofthe. property -to the North. --water to the residence is supplied from a well drilled on the southeast side of the 60 feet away -from the house. The well is located a sufficient distance from obvious sources of contamination, such as the-. exi pptic,_ em locations and corrals — ---- -Walsh- Septic System -Investigation ---------- and Percolation Tests 0395 Valley Road July 24, 1996 Page 2 Existing On -site Wastewater Disposal System Eagle County was unable to locate a permit for the existing septic system by reviewing the County Environmental Health Department records. The current septic system, however, is reported to be a small 750 or 1000 gallon metal septic tank and a seepage pit of cinder block cone construction. Subsurface Conditions: A sail ` profile within the proposed absorption area was excavated to a depth of eleven feet. The excavation revealed that there was no groundwater apparent or bedrock present within the excavation. The soils consisted of about 6 inches of dark reddish gray sandy loam topsoil. The subsoil below that to a depth of thirty inches was a sandy loam grading to a very gravelly sand with numerous cobbles from two inches to eighteen inches in diameter to the bottom of the soil profile pit. The soil was calcareous below a depth of twenty inches. The subsurface soil conditions were evaluated with the standard percolation test procedures at the approximate location shown on Figure 1. Before the test, the sidewalls were scraped and gravel was placed in the test holes to prevent scouring when water was added. Percolation Testing: Percolation testing was performed in the proposed absorption bed area North of the residential building. This testing was performed in holes excavated by hand to a total depth of thirty inches. An initial filling of the percolation test holes was done by adding approximately 5 gallons of water to the hole in the morning of the day the percolation test was conducted. The percolation holes were then further pre-soaked by adding water to refill the test holes to a depth of fourteen inches several times for the eight hour period before beginning the percolation test. The results of the percolation testing are presented in Table I. These results indicate the sandy loam in this area has an average percolation rate of 17 minutes per inch, a satisfactory percolation rate under Eagle County criteria. However, it was noted that just below the depth of the test holes the subsoils become a quite course gravelly sand with numerous cobbles. This is considered, by regulations and State law, an unsuitable soil for use in conventional septic construction. Further, because of the depth of the basement plumbing, a _pump is required to lift and distribute septic tank effiuent inthe.- proposed absorption field area. Because this soil is not considered acceptable for a conventional infiltration design for the on -site sewage system and because a pump is required for use in the septic 2 Walsh Septic System Investigation and Percolation Tests 0395 Valley Road July 24, 1996 Page 3 system, we refer you to E. O. Church, Inc -,Consulting Engineers and Geologists to develop a s119, specific design to address these soil and site`conditions. Limitations: This report has been prepared according to generally accepted practices in this area for use for sewage disposal design purposes. The conclusions and recommendations submitted in this report are based upon data obtained from our site visits at the location indicated. There is some possibility that the nature and extent of variations in the subsurface soils across the site may not have been evident at the time of this investigation, and may need additional evaluation, if further excavation reveals conditions different from those described. This office should be advised of any unusual situations as soon as possible so that we may reevaluate our recommendations.
