A seasonally high water table was located at 22", 24" 6 26", <br />(mottled soil). Due to the seasonally high water table, a pressurized <br />mound system will need to be installed. The bottom of the rock bed <br />must be located at least 3* above the seasonally high water table. <br />The soils at a depth of 12" have a percolation rate averaging 5.7 <br />min/inch and are adequate for treating septic effluent. <br />A pumping chamber will need to be installed to lift the effluent to the <br />treatment area. <br />The manifold and supply line pipe must have back drainage to the pumping <br />chamber. The distribution pipes shall have their ends capped. Be sure <br />the rock and sand fill material are clean. The sod layer below the <br />entire mounded area must be turned over, just break up the sod, be sure <br />not to over work. <br />^e power supply and switches must be located outside the manhole and <br />pumping chamber in a weather proof enclosure. A warning device must be <br />Installed with a light and sound device, this is in case of a pump failure. <br />(Mercury floats are a good method). <br />All neighboring wells are located more than 100‘ away from the proposed <br />treatment area. <br />Cont'D <br />Soil ee^ Fercolsllee Tetlf <br />Si^flc Sytt9m D^igm
