REVISED SITE EVALUATION REPORT for Lot 2,Block 1,Kokesh Farm <br /> Sewage Treatment System Page 4 <br /> Sandy loam soil shall be placed on the filter�terial to a depth of 12 inches in the center of the mound and <br /> to a depth of 6 inches at the sides. <br /> Six inches of topsoil shall be placed on the fill material over the entire area of the mound. A grass cover <br /> shall be established over the entire area of the mound. No shrubs shall be planted on the top of the mound. <br /> Shrubs may be placed at the foot and side slopes of the mound. <br /> The side slopes of the mound will be 4 feet horizontal to 1 foot vertical(4:1). This gentle slope will allow <br /> easy mowing of the gass cover. The soil material at the toe of the dike should be slightly less permeable <br /> or som�what tighter than the na.tural soil below the mound. This can be accomplished by selecting a finer <br /> soil or by compaction. <br /> Whenever mounds are located on slopes, a diversion shall be constructed immediately up slope from the <br /> mound to intercept and divert runoff. <br /> PIJMP AND COLLECTION TANK: <br /> A pump shall be used to deliver effluent to the mound. The pump shall be cast iron or bronze fitted with <br /> stainless steel screws or constructed of other sound, durable and corrosion resistant materials. <br /> The pump installed will need to deliver 66.6 gallons per minute with a head of at least 20 feet. An alazm <br /> device shall be installed to warn of pump failure. Install the pump control and a Meyers, Model D.L.V. <br /> Audio Visual, Lo-Voltage alarm system or approved equal in a conspicuous place at the direction of the <br /> owner. <br /> Dosing Volume=25% of 750 g.p.d. = 188 gallons. <br /> DRAINFIELD ROCK REOUIRED: <br /> Based on 12 inches of rock,27.8 cubic yards of rock would be required. <br /> SAND REOUIRED: <br /> Approximately 350 cubic yards of clean sand for under mound is needed. <br /> TE • <br /> A.
