The seasonally saturated soils were located at 12"-18"(mottled soil). Due to seasonally saturated soils,a pressurized Mound System will need to be installed to treat septic effluent. The bottom of the treatment area must be located at least 3'above the saturated soils. The soils at a depth of 12"have a percolation rate averaging 6 MPI. The existing house is going to be remodeled. The existing tank must be abandoned.If the house is remodeled the septic outlet for the house should be redirected to the east side of the house. A tank filer and clean outs on the laterals must be installed. All neighboring wells are located greater than 100'away from proposed treatment area. A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and switches must be located outside the manhole and pumping chamber in a weatherproof enclosure. A warning device must be installed with light and sound devices;this is in case of a pump failure.The manifold and supply line must have back drainage to the pumping chamber. The distribution pipes shall have their ends capped. Be sure the rock and sand fill materials are clean. The sod layer below the entire mounded area must be turned over,just break up the sod and be sure not to over work. Keep all heavy equipment off of the proposed treatment areas before.during and after construction. The area around both sites must be fenced off by the contractor before any construction begins.This Design is not valid and the System will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. With proper installation and maintenance,this system should have no problem in treating septic effluent effectively. Nothing other than gray water,(laundry,showers,etc.) Human water and toilet tissue should be disposed of into the septic tanks. Garbage disposals are not recommended. Additives must not be used;they may cause harmful damage to your septic system. It is recommended that you pump the tank every year for 1 tank,every two years for two tanks.
