The periodically saturated soils were located at 12"-16"(mottled soil).Due to the periodically saturated soils,a pressurized mound system will need to be installed to treat the 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 12AMPI. The absorption areas due not overlap. All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.Clean outs must be installed on the end of the laterals for maintenance. Use 7/32 inch perforations on the laterals. All neighboring wells are greater than 100'from proposed treatment areas. A 1300 gallon 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. Keen all heavy eauioment off of the or000sed treatment areas before,during and after construction. The area around both sites must be fenced off by the contractor before any construction begins. 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 septic tanks every two years.
