Due to the periodically <br /> saturated soils, a pressurized mound system with 6 inches of rock will need to be installed to treat the septic <br /> effluent. The bottom of the treatment area must be located at least 3' above the saturated soils. This system <br /> is designed with 6 inches of rock. <br /> The absorption areas of the existing primary and future sites do not overlap. <br /> All neighboring wells are greater than 100' from proposed treatment areas. <br /> The soils at a depth of 12"lave a percolation rate averaging 4.7 MPI. <br /> A 1300 gallon pumping chamber will need to be installed to lift the effluent to the treatment area. The <br /> power supply and switches trust be located outside the manhole and pumping chamber in a weatherproof <br /> enclosure. A warning device must be installed with light and sound devices;this is in case of a pump <br /> failure. A flow measurement device must be installed.
