The periodically saturated soils were located at 16"-18"(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. All neighboring wells are greater than 100' from proposed treatment areas. The soils at a depth of 12"have a percolation rate averaging 10 MPI. ��o COPY The existing tanks must be abandoned. All new tanlcs need to be insulated if there is less than two feet of cover over the top of the tanks and a filter installed on the second tank.Clean outs must be installed on the end of the laterals for maintenance. Keep all heavy Equipment off the�roposed treatment areas before durin�and after construction. A pumping chamber will need to be installed to lift the ei�luent 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 pump chamber.The rock and fill materials must be 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. Not6in�other than grav water (laundrv 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 mav cause harmful damaee to vour septic svstem. It is recommended that vou aump the tanks every two vears.
