Co., MN <br /> This on-site sewage treatment system is designed for a Type 1, five bedroom home, in <br /> accordance with the Minnesota Pollution Control Agency Chapter 7080 and local <br /> ordinances. <br /> The soils on this site are SCS soils mapped - HbC - Hayden loam & NeB - Nessel loam. <br /> The seasonally saturated soils were located at 18" to 28" (mottted soil). Due to the <br /> seasonally saturated soils, a Pressurized Mound System will need to be installed to treat <br /> septic effluent. The bottom of the treatment area must be located at least 3' above the <br /> saturated soils. <br /> The future expansion site is a pressurized mound system split into two rock beds 10'x34' <br /> each. The effluent wiil be delivered by installing the supply line to each rock bed with <br /> the pump chamber altemating rock beds using the highest head pressure for the pump <br /> selection. <br /> The soils at a depth of 12" have a percolation rate averaging 4.0 mpi. <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 waming device must be installed with a light <br /> and sound device, this is in case of a pump failure. <br /> 1 <br />
