S�hirmers _. <br /> ' October 2, 1989 <br /> Dan Parten ' <br /> 4300 Bayside Rd. <br /> Existinq House <br /> Orono, Henn. Co. , MN <br /> This system is Designed for a �i�ype i, �our bedroom home and in accordance <br /> with the Minnesota Pollution Control Agency Chapter 7080 and local <br /> ordinances . <br /> The soils on this site are typical of SCS soils mapped - KIC2- Kilkenny <br /> clay loam. A seasonally hign water table was located at 12" , 14" & <br /> 20" , (mottled soil ) . This site has an existing pressurized mound system. <br /> The site was tested for future expansion for a Sub-Division. Due to the <br /> � seasonally high water table, the future expansion area will need to be <br /> a pressurized mound system. The bottom of the rock bed must be located <br /> at least 3 ' above the seasonally high water table. <br /> The soils at a depth of 12" have a percolation rate averaging 21. 1 <br /> min/inch and are adequate for treating septic effiuent. <br /> A pumping chamber will need to be instalied to lift �ne effluent to the <br /> treatment area. <br /> The manifold and supply l,ine pipe must have back drainage to the pumping <br /> chamber . The distribution pipes shall have their ends capped. Be sure <br /> the rock and sand fill material are clean. The sod layer below the <br /> entire mounded area must �be turned over, just break up the sod, be sure <br /> not to over work. <br /> The power supply and switches nust be locat�:� outside the manhole and <br /> pumping chamber in a weat,her proof enclosure. A warning device must be <br /> installed with a light and sound device , this is in case of a pump failure. <br /> (Mercury floats are a good method) . <br /> All neic�hboring wells are located more than 100 ' away. from the proposed <br /> treatment area . <br /> Keep all heavy equipment off of the proposed treatment area before and <br /> after construction as much as possible . The treatment area should be <br /> marked off bef ore construction. � <br /> ' CONT ' D <br /> Soi! and Percolation Tests <br /> Septic System Design <br />
