No. 627 <br /> � 951 Katydid Lane E • St. Michael, MN 55376 • (612) 497-3566 <br /> Novembe 19 , 1994 <br /> Mark Harrington <br /> 4080 Bayside Rd. <br /> Orono , Henn. Co . , MN I <br /> This site has an existing Pressurized Mo nd System for a 3BR home . <br /> The system will be increased for a SBR h me . <br /> The mound will be added to at each end o the rock bed . The <br /> existing mound will need the topsoil rem ved to the washed sand <br /> with a backhoe with no travel on the mou d. The tank capacity <br /> will require an additional 1000 gallon h lding tank. The pumping <br /> chamber is a 1000 gallon capacity which eets City code for minimum <br /> capacity. Recommend to reshape and dive t the run off away f�om <br /> the pumping chamber . <br /> The future expansion is on 7o to 90 slope & will need approval <br /> by the City Official . <br /> The soi7..� at a depth of 12" have a perc lation rate averaging <br /> 2 . 9 min/inch. <br /> Al1 neighboring wells are located great r than 100 ' away from the <br /> proposed treatment area. <br /> Keep all heavy equipment off of the pro osed treatment area before <br /> and after construction. The treatment rea should be marked off <br /> before construction. This Design is no valid & the system will <br /> need to be relocated if failure to prot ct the areas proposed <br /> for On-Site Sewage Treatment occurs. <br /> With proper installation and maintenanc , this system should have <br /> no problem in treating septic effluent ffectively. <br /> Nothing other than gray water (laundry, showers , etc . ) human waste <br /> & toilet tissue should be disposed into the septic tanks . Garbage <br /> disposals are not recommended. Excessi e amounts of soaps , cleaning <br /> agents & chlorine agents may kill the b cteria needed to treat <br /> septic effluent. Additives are not rec mmended . Recommend to pump <br /> & clean your tank through the manhole b a certified pumper every <br /> year if you have 1 tank and every 2 yea s if you have two tanks . <br /> ; /�_ � . <br /> f <br /> even B.
