The <br />existing tank(s) art, old and will need to be abandoned, pumped & <br />filled with soil. <br />The soils on this site are SCS soils mapped - HbC - Hayden loam. <br />A seasonally high water table was located at 14" & 20", (mottled <br />soil). Due to the seasonally high water table, a Pressurized <br />Mound System will need to be installed. The bottom of the rock <br />bed must be located at least 3' above the seasonally high water <br />table. <br />The soils at a depth of 12" have a percolation rate averaging <br />11.7 min/inch. <br />A pumping chamber will need to be installed to lift the effluent <br />to the treatment area. <br />The manifold and supply line pipe must have back drainage to the <br />pumping chamber. The distribution pipes shall have their ends <br />capped. Be sure the rock and sand fill material are clean. The <br />sod layer below the entire mounded area must be turned over, just <br />break up the sod, be sure not to over work. <br />The power supply and switches must be located outside the manhole <br />and pumping chamber in a weather proof enclosure. A warning device <br />must be installed with a light and sound device, this is in case of <br />a pump failure. (mercury floats are a good method). <br />All neighboring wells are located greater than away from the <br />proposed treatment area. <br />CONT'D •__ <br />t <br />�ZZ�o. <br />
