I" This report presents the results of percolation tests and provides septic system recommendations for the proposed single family residence on Lot R-28, South Forty Subdivision, Filing No. 1, Eagle County, Colorado. SITE INVESTIGATION This site was investigated on April 27, 1990, and three percolation tests were dug to a minimum depth of 27 inches_ Holes were presoaked and percolation tests performed. Results o•f these tests are included in this report; see PERCOLATION TEST RESULTS. The locations of the percolation test holes are shown on drawing No. 1. SITE LOCATION AND DESCRIPTION The site is located on Lariat Loop in Eagle County, Colorado. The site slopes to the north at approximately .16%. Drainage in the area of the proposed absorption trenches is to the north. Vegetation consists of sage brush and sparse grasses. SUBSURFA+;F AND GROUNDWATER CONDITIONS Subsurface conditions in the proposed leach field area are relatively uniform, and consist of 1 foot of topsoil underlain by sandy silt to a depth of 9.5 feet. Between 9.5 feet and 10 feet, the soil consists of sandy silt with weathered rock fragments_ No groundwater was encountered during excavation. PERC_'oLATTi)N TEST RE ;!TITS A total of three percolation tests were performed on the site as specified by the Eagle County Individual Sewage Disposal System Regulations. Results were as follows: Test Hole Min./1" DroE Uate of Ted Ambient Air Temp. 60 2 40 4/ 2 r ,/90 60 3 1(1 1,:2 4/27,/9-0 60 Average time for 1 inch drop = 26 3/4 minutes A single-family residence has been proposed for this site for year-round use. The residence will have a total of four (4) bedrooms, and will be equipped with a garbage disposer and automatic clothes washing machine. Thus design criteria for calculations are: 2 persons/bedroom 75 gallons,/person/day-average flow +20% absorption area for garbage disposer +40% absorption area for automatic washer -25% absorption area for dosing tank Maximum flow: 150%. of average flow A= Q I Where A= minimum absorption area (sq. ft.) 5 Q= maximum quantity of sewage flow (gal/day) T= percolation rate (min/inch) Q= 4 x 2 x 75 x 1.5 = 900 gal/day A= 0 T = 900 26.75 = 931 sq. ft. S 5 +931 sq. ft. base calculation +186 sq. ft.(disposal +20%) +372 sq. ft.(washer +40%) -233s5. ft ( dosing -25% ) 1256 sq. ft. absorption area 4 From table 5, a minimum area of 250 sq. ft. per bedroom is required. (250 x 4 = 1000 sq. ft., which is less than 1256 sq. ft.) Minimum area of absorption trench is 1256 sq. ft. From Table 4 (section 4.07.01 of the Eagle County Regulations), a 1250 gallon septic tank is required - SEPTIC SYSTEMS RECOMMENDATIONS Based on the proceeding calculations, it is recommended to install a 1250-gallon compartmented septic tank with automatic alternating dosing chamber followed by a minimum of 1256 square feet of seepage trench_ The seepage trench should lie a minimum of 10 feet from all property lines, and 20 feet from the proposed residence. An inspection of the system should be made by a representative of the Eagle County Environmental Health Department prior to backfilling. The installation and material specifications must comply with the Eagle County Individual Sewage Disposal System Regulations. As an alternative to the standard absorption trench, 420 lineal feet of SB2 10-inch diameter "gravel -less" leach bed tubing (as manufactured by Advanced Drainage Systems, Inc.) may be embedded in the native soils of the site. (one lineal foot of pipe is required for each three square feet of absorption trench area). A dosing chamber with dual alternating siphons shall be installed. The dosing chamber will allow for periodic high rate 5 discharge to alternating portions of the field. This would prolong the life of the drainage field. CONCLUSIONS This report has been prepared for the exclusive use of Cecilia Folz for the specific application to the proposed single- family residence at Lot R-28, South Forty Subdivision: Filing No. 1, Eagle County, Colorado_ The findings and recommendations of this report have been obtained in accordance with accepted professional engineering practices.
