Due to the periodically saturated <br /> soils,a pressurized mound system with 6 inches of rock will need to be installed to treat the septic effluent. <br /> The bottom of the treatment area must be located at least 3' above the saturated soils. This system is <br /> designed with 6 inches of rock. <br /> The soils at a depth of 12"have a percolation rate averaging 8.7 MPI. <br /> All tanks need to be insulated if there is less than two feet of cover over the top of the tanks. Clean outs <br /> must be installed on the end of the laterals for maintenance. <br /> Use 7/32 inch perforations on the laterals. <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 must 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. The manifold and supply line must have back drainage to the pumping chamber. <br /> Keen all heavv epuipment off of the nroposed treatment areas before durine and after construction <br /> The area around both sites must be fenced off bv the contractor before anv construction be�ins <br /> With proper installation and maintenance,this system should have no problem in treating septic effluent <br /> effectively. Nothing other than gray water, (laundry, showers,etc.)Human water and toilet tissue should be <br /> disposed of into the septic tanks. Garbage disposals are not recommended. Additives must not be used they <br /> may cause harmful damage to your septic system. It is recommended that you pump the septic tanks every <br /> two years. <br /> Si rely, <br /> Joseph J.
