There may be more sites available. <br /> The periodically saturated soils were located at 18-30 Inches(mottled soil). Due to the <br /> periodically saturated soits,a pressurized mound system will need to be installed to treat the <br /> septic ef�7uent.The bottom of the treatment area must be located at least 3' above the saturated <br /> soils. <br /> The soils at a depth of 12"have a percolation rate averaging 3 MPI. <br /> A pumping chamber will need to be installed to lift the effluent to the treatment area. The power <br /> supply and switches must be located outside the manhole and pumping chamber in a <br /> weatherproof enclosure. A warning device must be installed with a light and sound device;this is <br /> in case of a pump failure. <br /> Use 7/32 inch uerforations on the laterals. <br /> Keep all heavy equipment off of the proposed treatment areas before and after <br /> construction.The treatment area must be fenced off before construction begins.This Design <br /> is not valid & the System will need to be relocated if failure to protect the areas proposed <br /> for the On-Site Sewage Treatment systems occurs. <br /> Nothing other than gray water,(laundry, showers, ect.)human water&toilet tissue should be <br /> disposed of into the septic tanks. Garbage disposals are not recommended. Additives must not be <br /> used;they may cause harmful damage to your septic system. It is recommended that you pump <br /> the septic tank s every two years. <br /> S�erely, Ci TY OF ��)lZC�N(� <br /> �...��,�._____e_____..
