NE, Hanover, MN 55341 (763) 498-8779 Fax (763) 498-8290 October 30, 2018 Swanson Homes 4665 St. Andrews Street Orono, Hennepin County This on-site Sewage Treatment System is partially designed for a Type 1, five -bedroom home in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The periodically saturated soils were located at 12-18 inches (mottled soil). Due to the periodically saturated soils, a pressurized mound system 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. Due to limited space. The mound rock bed must be split into two 32 -foot rock beds. The absorption area of the proposed systems does not overlap. This system is designed as a non- level pressurized trench system using gate valves to equalize the pressure. Use 7/32 -inch perforations on the laterals. The soils at a depth of 12" have a percolation rate averaging 9 MPI.. All neighboring wells are located greater than 100' away from proposed treatment area. A 2250 -gallon septic tanks are to be installed. All 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 Darwin precast pumping chamber must 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. The manifold and supply line must have back drainage to the pump chamber. Keep all heavy equipment off of the proposed treatment areas before, during and after construction 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 water and toilet tissue should be disposed of into the septic tanks. Iron filters cannot go into the septic system. 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 septic tanks every two years.
