Olson--MPCA License #810 11481 Riverview Rd. NE, Hanover, MN 55341 (763) 498-8779 fax (763) 498-8290 NEW FUTURE SITE FOR THE NEW HOUSE USING THE EXISTING MOUND August 19,2016 Brian Merz 5z-01 OG B Lot 1,Block 1 White Oak Funk Add. Orono,Hennepin County This on-site Sewage Treatment System is designed for a future Type 1 five-bedroom home in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The new house is a four bedroom house.The existing mound is compliant for a four bedroom house and can be reused.A compliance inspection form is attached. Keep all heavy equipment off the existing and new future septic sites. The periodically saturated soils were located at 16-18 inches(mottled soil). Due to the periodically saturated soils, a pressurized mound system with 6 inches of rock will need to be installed to treat the septic effluent. The bottom of the treatment area must be located at least 3' above the saturated soils. This system is designed with 6 inches of rock. The absorption areas of the existing primary and future sites do not overlap. All neighboring wells are greater than 100' from proposed treatment areas. The soils at a depth of 12"lave a percolation rate averaging 4.7 MPI. A 1300 gallon pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and switches trust 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. A flow measurement device must be installed. Including but not limited to a water meter,event counter,running time clocks or electronically controlled dosing. Nothing other than gravater,(laundry,showers,etc.)Human water and toilet tissue should be disposed of into the septic anks. Garbage disposals are not recommended. Additives must not be used; they may cause harmful damage to your septic system.It is recommended that you pump the tank every year for 1 tank, every two years for two tanks.
