PERCOLATION TEST RESULTS AND SEPTIC RECOMMENDATIONS FOR LOT R-26, SOUTH FORTY SUBDIVISION EAGLE COUNTY, COLORADO PREPARED FOR: MIKE PLANT PROJECT NUMBER V-1188E JULY 1981 pay VSo BOX C-100 1420 VANCE STREET AVON, CO 81620 LAKEWOOD, CO 80215 949-5072; DENVER 893-1531 232-0158 SCOPE This report presents the results of a percolation test and provides septic system recommendations for the proposed residence located on Lot R-26, South Forty Subdivision, Eagle County, Colorado SITE LOCATION AND DESCRIPTION The site is located in a part of the Southeast one - quarter of Section 5, Township 5 South, Range 82 West of the Sixth Principal Meridian, Eagle County, Colorado. More particularly, the site is described as Lot R-26, South Forty Subdivision. The site drains to the north and vegetation consists of sage brush and native grasses. SUBSURFACE AND GROUNDWATER CONDITIONS Subsurface conditions are fairly uniform with topsoil to a depth of one foot underlain by very silty sand with gravel and cobbles. PERCOLATION TEST RESULTS A total of three percolation tests were performed on the site using the.standard test method as described by the Eagle County Individual Sewage Disposal Regulations. The test holes were dug and presoaked by the client on July 23, 1981. The test was performed on July 24, 1981, by Inter -Mountain Engineering, Ltd. The results were as follows: Test Hole No. 2 3 Time .used for design: DESIGN CRI TER I A Min/1" Drop 6 min. 8 min. 5 min. 6.3 min. E The house will have three bedrooms and will include a garbage grinder and automatic washing machine. Assumptions used in the calculations were: Three bedrooms with garbage grinder and automatic washing machine. 2 persons/bedroom 75 gallons/person/day Maximum flow: 150% of average daily flow 3 Calculations:- A = Q 5 5T where A = minimum absorption_ area Csq. ft.) Q = estimated quantity of sewage flow (gal/day) T = percolation rate (min/inch) Q= 2 x 3 x 75 x 1.5 = 675 gal/day A = 6755Y6. 3 = 340 sq. ft. Absorption area to be increased 20% for a garbage grinder and 40% for the automatic washer (County Regulation 8.1 e). 340 x 1.60 = 544 sq. ft. Since a seepage bed is to be used, the absorption area is to be increased by an additional 30% (County Regulation 8.1 h). 544 x 1.30 = 707 sq. ft. Due to subsidence problems in this area, the seepage bed should be increased by another 30%. 707 x 1.30 = 919 sq. ft. - Use 18 x 51 From Table 4 (Section 7.1 of the County Regulations), the minimum tank size shall be 1000 gallons. SEPTIC SYSTEM RECOMMENDATIONS Based on the preceding calculations, recommendations are for a minimum of a 1000 gallon compartmented septic tank to 4 SEPTIC SYSTEM RECOMMENDATIONS - continued be followed by a minimum 919 square foot seepage bed. The bed should lie a minimum of ten feet from property lines and twenty feet from the proposed residence. Inspection of the system should be made by a representative of Inter -Mountain Engineering, Ltd., and by a representative of the Eagle County Environmental Health Department prior to backfilling. Excerpts from the Eagle County Individual Sewage Disposal System Regulations have been included as Appendix A. The installation and material specifications in these regulations must be followed. CONCLUSIONS This report has been prepared for the exclusive use of Mike Plant for the specific application to the proposed residence located on Lot R-26, South Forty Subdivision, Eagle County, Colorado. The findings and recommendations of this report have been obtained in accordance with accepted professional engineering practices in the field of Foundation Engineering and Soil Mechanics.

Tanks are to be installed on a solid base and shall be level. The tank shall be installed with removable covers or manholes extended to within 8 inches of finished grade in order to provide access tc the inlet and outlet devices of each compartment for cleaning and inspection. Roof drains, foundation drains, area drains, or cistern overflows are not to enter the tank or any part of the treatment system. b. The building sewer line to septic tank shall be laid with a minimum fall of 1/8th inch per foot (1/4th inch fall/ft. vi a relatively even distribution of effluent over the system will occur. When, at the discretion of the Health Officer, it is necessary to maintain grade or alignment of the tile or pipe lengths, all tile or pipe lengths shall be placed on narrow grade boards which are securely staked. The grade of pipelines shall be from zero (0) inches to 4 inches per 100 feet. c. A final cover of soil suitable for vegetation at least 10 inches deep shall be placed from the top of the hay, straw, or other similar pervious material to the finished surface grade of an absorption trench or seepage bed. The final cover shall be graded to deflect runoff water away from the disposal area. In the case of an above -ground system, such as a mounded system, an impervious berm shall be constructed to prevent lateral flow of waste discharge outside of the absorption field. Machine tamping, rolling, or hydraulic compaction of final cover shall not be permitted; however, hand tamping may be allowed where necessary to stabilize'the soil to prevent erosion or the intrusion of_ extraneous water. '8.3 Seepage Beds _ a. Seepage beds shall be constructed with a length not exceeding 100 feet; a width not greater than 100 feet and a depth not exceeding 3 feet (unless approved by the Health Officer). A 12-inch layer of 1/2 inch to 2-1/2 inch washed gravel shall be distributed evenly over the entire bed, with pipelines set at a -depth to insure at least 6 inches of gravel below and 2 inches of gravel above each line. The bottom of the bed shall be level. A covering of untreated building paper, straw, or similar material, shall be placed on top of the gravel, and after final inspection, backfill shall be placed over the bed to a minim -am depth of 10 inches. The bottom in the bed and distribution lines shall be laid level or up to a 4-inch drop in 100 feet. vii b. The outermost disposal lines in the bed shall be placed no less than 18 inches and no more than 36 inches from its outside bedwalls. For each 6 feet or part thereof, in bed width, there shall be one disposal line extending the length of the bed. Such lines shall be so placed as to distribute the effluent evenly over the entire bed area, and shall be level or unto a 4-inch drop in 100 feet. A distribution box or other distribution device providing uniform application of flow shall be included in the seepage bed system. viii Soil Sample SM/SC' Project South 40 Subdivision --Edwards Sample Location T.H.
