CO?). <br /> The existing tank must be abandoned. <br /> All new tanks need to be insulated if there is less than two feet of cover over the top of the tanks and a filter <br /> installed on the second tank.Clean outs must be installed on the end of the laterals for maintenance. <br /> A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and <br /> switches must be located outside the manhole and pumping chamber in a weatherproof enclosure. A <br /> warning device must be installed with light and sound devices;this is in case of a pump failure.The <br /> manifold and supply line must have back drainage to the pump chamber.The rock and fill materials must <br /> be clean.The sod layer below the entire mounded area must be turned over.Just break up the sod and be <br /> sure not to over work. <br /> 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. Additives must not be <br /> used;they may cause harmful damage to your septic system. It is recommended that you pump the <br /> tank every year for 1 tank,every two years for two tanks. <br /> erely, <br /> Creel,ORONO <br /> Joseph J.Olsonp� 1 11 <br /> DAT - PERMIT <br /> Ci/MC)COPY APPROVED AS I►t RVITTED <br /> �] APPROVED WITH CORRECTIONS AS NOTED <br /> Q NOT APPROVED-CORRECT&RESUBMIT <br /> These comments arc for your information.
