ORONO COPY <br /> The existing septic tanks and lift station may be used upon approval of the local inspector. <br /> The manifold and supply line must have back drainage to the pump chamber.The rock and fill materials <br /> must be clean.The sod layer below the entire mounded area must be turned over.Just break up the sod and <br /> be sure not to over work. <br /> Nothing other than Bray 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 /> Sincerely, <br /> CITY OF ORONO <br /> /Joseph J.Olson SEPTIC PERMIT PLAN REVIEW <br /> ORONO Copy INSPECTOR <br /> DATE PERMIT NO. <br /> M APPROVED AS SUBMITTED <br /> 0 APPROVED WITH CORRECTIONS AS NOTED <br /> Q NOT APPROVED-CORRECT&RESUBMIT <br /> THIS SMEM IS OMM MR These comments are for your information.
