Due to the periodically saturated <br /> soils,a pressurized mound system will need to be installed to treat the septic effluent.The bottom of the <br /> treatment area must be located at least 3' above the saturated soils. <br /> The soils at a depth of 12"have a percolation rate averaging 4 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 /> The absorption area of the future site does not encroach into the primary site. <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 /> Keep all heavy equipment off of the proposed treatment areas before,during and after construction. <br /> The area around both sites must be fenced off by the contractor before any construction begins. <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 /> Sincerely, <br /> ITY OF G 'vim <br /> Joseph J.
