Due to the periodically <br />saturated soils, a pressurized mound system with 6 inches of rock will need to be installed to treat the septic <br />effluent. The bottom of the treatment area must be located at least 3' above the saturated soils. This system <br />is designed with 6 inches of rock. mumr <br />The absorption areas of the two systems do not overlap. R !"f� TK,E �. N <br />The soils at a depth of 12" have a percolation rate averaging 9.1 MPI. _3. Ga <br />A 2250 -gallon septic tank is designed for this site. All tanks need to be insulated if there is less than two <br />4U00feet of cover over the top of the tanks. Clean outs must be installed on the end of the laterals for <br />maintenance. <br />Use 7/32 inch perforations on the laterals. <br />A Darwin 1300 gallon pumping chamber will need to be installed to lift the effluent to the treatment area. <br />The power supply and switches must be located outside the manhole and pumping chamber in a <br />weatherproof enclosure. A warning device must be installed with light and sound devices; this is in case of <br />a pump failure. A flow measurement device must be installed. Including but not limited to a water meter, <br />event counter, running time clocks or electronically controlled dosing. <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. iron filters cannot go into this <br />system. Additives must not be used they may cause harmful damage to your septic system. It is�S��S, <br />recornmended that <br />®you pump the septic tanks every two years.
