ORONO COPY 3205 Graham Hill Road Orono,Hennepin County This on-site Sewage Treaiment System is 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 16"-20"(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. The soils at a depth of 12"have a percolation rate averaging 7 MPI. 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. The primary site will need a retaining wall on the downhill toe at the conservation easement line.T'he toe cannot cross the easement line. - The absorption area of the future site does not encroach into the primary site. A 1250 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 tight and sound devices;this is in case of a pump failure_The manifold and supply line must have back drainage to the pumping chamber. Keea all heavv eauipment off of the aroaosed treatment areas before,during and after construction. The area around both sites must be fenced off bv the contractor before anv construction begins. 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.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.
