Care must be taken when the existing <br />mound is removed because it will now be the future site. <br />The periodically saturated soils were located at 20-24 inches (mottled soil). 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. <br />All neighboring wells are greater than 100' from proposed treatment areas. <br />The soils at a depth of 12" have a percolation rate averaging 9.1 MPI. <br />The existing septic tanks and lift station may be used. <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. Iron filters cannot go into the septic sstem. Garbage disposals are not <br />recommended. Additives must not be used they may cause harmful damage to your septic system. It is <br />recommended that you pump the septic tanks every two years. <br />Sincerel <br />Joseph J. Olson <br />
