�-P TESTING� �NC. Steven B. Schirmers • MPCA Cert.No. 627 951 Katydid Lane NE • St. Michael, MN 55376 • (612) 497-3566 FAX (612)-497-5011 State License #394 , March 1, 1997 Jyland Development Lot 2, Block 1 Hunter Pass Orono, Henn. Co., MN � This on-site sewage treatment system is designed for a Type 1, five bedroom home, in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The soils on this site are SCS soils mapped - HcC2 - Hayden clay loam. The seasonall�y saturated soils were located at 14" to 24" (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 future expansion site is a pressurized mound system split into two rock beds each 10'x32'. The effluent would be delivered by installing a supply line to each rock bed with the pumping chamber altemating rock beds using the highest head pressure for the pump selection. The soils at a depth of 12" have a percolation rate averaging 10.6 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 waming device must be installed with a light and sound device, this is in case of a pump failure. ; The manifold and supply line 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 tumed over, just break up the sod, be sure not to over work. 1
