A1�11YlNCREASE IN NUMBF.it <br /> �Bf�R�VIS��TES IHIS DESIGI�, <br /> This site has an existing on-site sewage treatment system which is surface discharging <br /> septic effluent. The system is classified as an imminent health hazard which must be <br /> repaired or disconnected within 10 months. <br /> T�;is on-site sewage treatment system is designed for a Type 1, four bedroom home, �n <br /> accordance with the Minnesota Pollution Control Agency Chapter 7080 and local <br /> ordinances. � - <br /> The soils on this site are a clay loam. The seasonally saturated soils were located at <br /> 22" to 28" (mottled soil). Due to the seasonally saturated soils, a Pressurized Mound <br /> System will need to be installed to treat septic efFluent. The bottom of the rock must be <br /> located at least 3' above the saturated soils. <br /> The soils at a depth of 12" have a percolation rate of 8.0 mpi. <br /> The existing tanks are block type which will need to be abandoned, pumped and filled <br /> with soil. <br /> A pumping chamber will need to be installed to lift the effluent to the treatment area. <br /> The power supply and switches must be located outside the manhole and pumping <br /> chamber in a weather proof enclosure. A warning device must be installed with a light <br /> and sound device, this is in case of a pump failure. <br /> 1 <br />
