The periodically saturated soils were located at 14-20 inches(mottled soil).Due to the periodically saturated soils,a pressurized mound system with 6 inches of rock will need to be installed to treat the septic ef�luent.The bottom of the treahnent area must be located at least 3' above the saturated soils.This system is designed with 6 inches of rock. The soils at a depth of 12"have a percolation rate averaging 10 MPI. 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. A 1250 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.A flow measurement device must be installed.Including but not limited to a water meter,event counter,running time clocks or electronically controlled dosing. Keen all heavv eauinment off of the nrouosed treatment areas before during and after construction The area around both sites must be fenced off by the contractor before anv 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 nor be used they may cause harmful damage to your septic system.It is recommended that you pump the septic tanks every two years.
