The design is based upon Garfield County requirements and physical site conditions. A field inspection of the site was made on July 22, 1988. Observations were made of three test holes at the leach field location. The location of the house with respect to the surrounding surface elevation will necessitate a pumped effluent system. The septic tank and soil absorption mound is located southwest of the house. The following parameters were used in the design of the system: o 4 bedroom single family home o Design flow rate = 150 gpd/bedroom o Natural ground slope less than 5% o Bedrock not encountered (assume greater than 4 feet) o Water table not encountered (assume greater than 24 inches but less than 48 inches at high water) o Minimum detention time in septic tank 30 hours The sewage effluent flow is calculated to be 600 gpd based on 4 bedrooms at 150 gpd/bedroom. A peak day multiplier of 1.5 was used for design purposes. Mr. William Vezzoso • August 4, 1988 Page 2 Septic Tank The septic tank shall be a prefabricated concrete or polyethylene tank with a minimum liquid capacity of 1200 gallons. The tank shall be installed in accordance with Garfield County requirements and shall be at an elevation capable of receiving sewage flow by gravity. Dosing Tank and Pump Septic tank effluent shall enter a water tight polyethylene or concrete dosing tank with a capacity of 300 gallons, which is approximately twice the volume of the pipe laterals. A low head submersible pump rated at 35 -50 gpm at 5 ft. of head, such as Hydromatic Model CW25 or equal, shall be installed in the dosing chamber. Soil Absorption Mound The soil absorption mound shall be as shown on the attached figures 7 -10, 7 -11 and 7 -13 which are from the EPA Design Manual for On -site Wastewater Treatment & Disposal Systems. The mound shall be located on natural ground within 25 feet of the dosing chamber. Topsoil shall be plowed or raked with backhoe teeth prior to placing the mound fill. Fill material shall be medium textured sand meeting the following grada- tion: Sieve Size Percent Passing #4 100 #10 75 -90 #16 35 -50 #50 15 -25 #200 0 -10 Results of a gradation test shall be provided by the supplier. For design purposes the sand shall be assumed to have a infiltration rate of 1.2 gpd /ft.2. Mr. William Vezzoso August 4, 1988 Page 3 The absorption bed material shall be porous media consisting of graded • gravel sized between 3/4 inch and 2 -1/2 inches. Fill material'and bed material should be readily available from local suppliers. The area of the absorption bed shall be 750 square feet based on a peak day flow of 900 gpd and an absorption rate of 1.20 gpd /ft. The mound shall be constructed on a relatively shallow grade and the percolation rate of the natural soils is relatively high. G1( ([/ The base are of the mound shall be a minimum of 1125 ft. based on 900 gpd and 0.8 gpd /ft. Mound dimensions for the system are as shown below. Refer to figure 7 -13 for location of dimensions. A = 18 ft. B = 42 ft. C = 1 ft. (minimum) E = 1 ft. (minimum) F = 0.75 ft. G = 1 ft. H = 1.5 ft. I = 12 ft. j1 ' J = 6 ft. (1) K = 9 ft. (1) L = 60 ft. W 36 ft. (1) actual dimension will vary slightly to meet 3:1 slopes The mound shall have six distribution laterals consisting of 4 inch dia- meter PVC drain tile placed 36 inches O.C. The laterals shall be connected with a 4 inch diameter PVC header on both ends. The distribution of the effluent to the mound will be in a 4 inch diameter PVC pipe. The purpose of the design and letter report is to assist you in obtaining a Garfield County permit for an on -site individual wastewater treatment system.

Broken Up' . 7.2.4.2 Application a. Site Considerations Site criteria for mound systems are summarized in Table 7 -7. These criteria reflect current practice. Slope limitations for mounds are more restrictive than for conventional systems, particularly for mounds used on sites with slowly permeable soils. The fill material and na- tural soil interface can represent an abrupt textural change that re- stricts downward percolation, increasing the chance for surface seepage from the base of the mound. • 241 • FIGURE 7 -10 TYPICAL MOUND SYSTEMS Cap I Straw, Hay or Fabric { Distribution Lateral Fill —\ Absorption Bed Topsoil M L C /nL.1 r / .Plowed Layer of Top Soil Slope ope - - ar'.. w.rs• .al!►im► "7 - 11/ =-:Rock Strata or Impermea•le Soil Layers - = (a) Cross Section of a Mound System for Slowly Permeable Soil on a Sloping Site.
