Once the hovse size,iocation and septic primary and future sites are chosen this design can be completed. The periodically sativated soils were located at 12-16 Inches(mottled soil).Due to the periorlically saturated soils,a pressurized mound system will need to be installed to treat the sepric effluent. The bottom of the treatment azea must be located at least 3'above the salurated soils. The soils at a depth of 12"have a percolation rate averaging 6.5 MPI. The absorprion areas do not overlap. All tanks need to be insulated if tliere is less than two feet of cover over the top of the tanks_A filter needs to be installed on the second tank.Clean outs must be installed on the end of the laterals for maintenance. A pumping chamber will need to be installed to lift the ef�luen#to the treatment area.The power supply and switches must be located outside the manhole and pumping chamber in a weatherproof enclosure.A waming device must be installed with a light and sound device;this is in case of a pump failure. Use 7/32 inch perforations on the laterals. Keep all heavy equipment off of the proposed treatment areas before and after construction.The treatment area must be fenced off before construction begins.This Design is not valid&the System witl need to be relocated if failure to protect the areas proposed for the On-Site Sewage Treatment systems occurs. Nothing other than gray water,(laundry,showers,ect.)human waier&toilet tissue should be disposed of into the septic tanks.Garbage disposals are not recommended.Additives must not be used;they may cause harmful damage to your septic system.It is recommended that you pump the septic tank every year for 1 tank,every two years for two tanks. incerely, CiTY OF ORONO _____--------- f" SEPTIC R I N R .
