.r <br />If <br />Mr. Ted Feig - 3 - June 8, 1981 <br />A submersible effluent pump capable of delivering at least 37.5 gallons per <br />minute against a total dynamic head of at least 15.9 feet should be selected. <br />Headlosses are calculated as follow: <br />1. Vertical headloss of 10.0 feet between pump discharge (approx. elev. <br />90.5) and manifold (approx. elev. 100.5), (assumes sewer invert below <br />footings) <br />2. Friction loss of 0.9 feet in 30 feet of supply pipe (3.03 feet per 100 <br />feet 2.0 inch I.D. plastic pipe), <br />3. Five (5.0) feet to account for losses in distribution network. <br />The primp should be rigged with mercury float switches to dose about 150 gallons <br />of effluent to the mound. An additional mercury float switch should be installed <br />on a separate circuit to an alarm device to warn of pump failure. The float <br />switches should be rigged to allow 600 gallons reserve capacity in the pumping <br />chamber. All electrical connections should be watertight. <br />The sole purpose of soils data contained herein is evaluation of soil suit- <br />ability for on -site absorption of septic tank effluent at the test site. <br />Although soil texture and horizonation information and ground water elevation <br />data may be helpful for the setting of basement elevations at this site, we <br />cannot warrant any such interpretations or use of this data for other purposes. <br />If you have any questions about information contained in this report, please <br />feel free to contact me. <br />Sincerely, <br />HAKANSON ANDERSON ASSOCIATES, LNC: <br />,(YAX'L' <br />Gary J. bun, Soil Scientist <br />GJR/Jkw <br />Enclosures <br />File: 839.01 <br />
