Address/Lot/Block: 585 Orchard Road • City: Orono County: Hennepin This On-Site Sewage Treatment System is designed for a Type 1, 6 bedroom home in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinance. A seasonally high water table or saturated soil layer was located at 24"to 36"(mottled soil). Due to the seasonally high water table or saturated soil and tighter sub-soils a Pressurized Mound System will need to be installed. The bottom of the rock bed must be located at least 3'above the seasonally high water table or saturated soil. The soils at a depth of 12"have a percolation rate averaging 6- 15 MPI. A pumping chamber will need to be installed to lift the effluent to the treatment area. 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 materials 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. 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. All neighboring wells are located greater than 50'away from the proposed treatment area. Keep all heavy equipment off of the proposed treatment area before and after construction. The treatment area should be marked off before construction. This design is not valid and the system will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. With proper installation and maintenance,this system should have no problem in treating septic effluent effectively. Nothing other than gray water,(laundry,showers,etc.)human waste and toilet tissue should be disposed of into the septic tanks. Garbage disposals are not recommended. Smaller amounts of laundry soaps,dish soaps,cleaning agents, etc.are better for the system. Antibacterial soaps and chlorine agents may kill the bacteria needed to treat septic effluent properly. Additives are not recommended, they may cause harmful damage to your system. Recommend to pump and clean your tanks by a certified pumper every other year if you have 1 tank and every 2-3 years if you have a 2-tank system to insure proper maintenance. 3/ 2e-r� Mark Tradewell Date MPCA#307
