Co., MN . This site has an existing on-site sewage treatment system classified as failed due to not meeting a 3' separation from the saturated soil. The only area available for a new system due to fill soil, compacted soil and low (wetland area) is in the area of the existing well. The well will need to be abandoned & relocated. This on-site sewage treatment system is designed for a Type 1, four bedroom home, in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. Approval will be needed to be 10' from the property line. The soils on this site are SCS soils mapped - HcC2 - Hayden clay loam. The seasonally saturated soils were located at 28" & 38" (mottled soil). Due to the seasonally saturated soils, a Pressurized Mound System will need to be installed to treat septic effluent. The bottom of the treatment area must be located at least 3' above the saturated soils. The soils at a depth of 12" have a percolation rate averaging 7.6 mpi. A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and switches must be located outside the manhole and pumping chamber in a weather proof enclosure. A warning device must be installed with a light and sound device, this is in case of a pump failure. The manifold and supply iine pipe must have back drainage to the pumping chamber. The distribution pipes shall have their ends capped. Be sure the rock and sand fill material are clean. The sod layer below the entire mounded area must be turned over, just break up the sod, be sure not to over work. 1
