Lot 4,Block 1 Graham Hill Preserve Orono,Hennepin County T"his on-site Sewage Treahnent System is designed for a Type 1 five-bedroom home in accordance with the Minnesota Poliution Control Agency Chapter 7080 and local ordinances. The periodically saturated soils were located at 16"-30"(mottled soil).Due to the periodically saturated soils,a pressurized mound system will need to be installed to treat the septic effluen�.The bottom of the treatment area must be located at least 3'above the saturated soils. All neighboring wells aze greater than 100'from proposed treahnent areas. T'he soils at a depth of 12"have a percolation rate averaging 9 MPI. Ail new tanks need to be insulated if there is less than two feet of cover over the top of the tanks and a filter installed on the second tank.Clean outs must be installed on the end of the laterals for maintenance. Use 7/32 inch cerforations on the laterals. Keea all heaw Eauipment offthe proposed treatment areas before during and after construction A p�unping chamber will need to be installed to lift the ef�luent to the treatment area. The power supply and switches must be located outside the manhole and pumping chamber in a weatherproof enclosure. A warning device must be installed with light and sound devices;this is in case of a pump failure.7'he manifold and suppiy line must have back drainage to the pump chamber.The rock and fill materials must be clean.T'he sod layer below the entire mounded azea must be turned over.Just break up the sod and be sure not to over work Nothin�other than erav water (laundrv,showers,etc.) Human water and toilet tissue should be disaosed of into the seatic tanks.
