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. <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 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 /> incerely, <br /> Joseph J.Olson CITY OF ORONO <br /> SBFTIC MR T?4 REV W <br /> INSPECTOR 9131- <br /> DAT$ PERMIT NQS <br /> APPROVBD AS SUVAr BD <br /> AM OVW WffK CORREQflaft AS m-fle <br /> _ WT AWJtOVBD4MRRWT&RBSUAWT <br /> mum �" " . we* cod&be "' <br /> �hctud+ss Neva na apeoiNeeNy soadYtYie aa� <br /> RiV i>�l1r111 Sited Sirs AT Aid.>� <br />
