Lot 1 <br /> Orono, Henn. Co., MN <br /> kJ' <br /> ((`v <br /> This site has an existing conforming mound system for a 5 bedroom home built in 1991. <br /> The supply line to the east was not connected to the system. To meet the requirement <br /> for a 6 bedroom home, 12' would need to be added to the existing rock bed to the west. <br /> The future site will also need a pressurized mound system. <br /> This on-site sewage treatment system is designed for a Type 1, 4 bedroom home & 2 <br /> bedroom guest home = 6 bedrooms, in accordance with the Minnesota Pollution Control <br /> Agency Chapter 7080 and local ordinances. <br /> The soils on this site are SCS soils mapped - KkC - Kilkenny loam. The seasonally <br /> saturated soils were located at 22" to 34" (mottled soil). The bottom of the treatment <br /> area must be located at least 3' above the saturated soils. <br /> The soils at a depth of 12" have a percolation rate averaging 3.7 mpi. <br /> A pumping chamber is installed to lift the effluent to the treatment area. The power <br /> supply and switches must be located outside the manhole and pumping chamber in a <br /> weather proof enclosure. A warning device must be installed with a light and sound <br /> device, this is in case of a pump failure. <br /> The manifold and supply line pipe must have back drainage to the pumping chamber. <br /> The distribution pipes shall have their ends capped. Be sure the rock and sand fill <br /> material are clean. The sod layer below the entire mounded area must be turned over, <br /> just break up the sod, be sure not to over work. <br /> 1 <br />
