NE, Hanover, MN 55341 (763)498-8779 Fax (763) 498-8290 October 31,2016 NOR-SON 500 Willow Drive S Orono,Hennepin County This on-site Sewage Treatment System is partially designed for a Type 1 five-bedroom home and a I bedroom guest house in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. Once the house size, location, lowest floor elevation and septic primary and future sites are chosen this design can be completed. The periodically saturated soils were located at 12-16 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 All neighboring wells are greater than 100' from proposed treatment areas. The soils at a depth of 12"have a percolation rate averaging 10 MPI. A 2250 combination septic tank needs to be installed for the house and a 1500 gallon combination for the guest house.The guest house is to be built first.The 1500 gallon combination tank should be used as a holding tank until the house is built. All new tanks need to be insulated if there is less than two feet of cover over the top of the tanks.Clean outs must be installed on the end of the laterals for maintenance. A 1300 gallon 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 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 gray water,flaundrv.showers etc)Human water and toilet tissue should be disposed of into the septic tanks 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 I septic tank,every two years for two septic tanks Sincerely, Joseph J.
