The periodically saturated soils were located at 18-20 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. The soils at a depth of 12"have a percolation rate averaging 5 MPI. ORONO COpy The existing septic system does not conform to the state code chapter 7080. The existing tanks maybe used upon approval of the local ins ct f the tanks are not useable.Two new 1000 gallon septic tank must be installed. cti,-t', a , 1-,e+-- k ('Kstp9-i. — All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.A filter needs to be installed on the second tank.Clean outs must be installed on the end of the laterals for maintenance. A 1000 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.The manifold and supply line must have back drainage to the pump chamber. 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 tank every year for 1 tank,every two years for two tanks.

Permits will be only issued to contractors holding a Minnesota Pollution Control Agency (MPCA) Septic System Installers License. 3. All work must be done in accordance with the approved septic system design. 4. The following inspections will be required for all septic systems: A. Tank installation prior to covering. B. Drainfield trench installation prior to covering. For mounds, inspection is required after rough up, but prior to sand placement (sand must be jar tested for silt content) and again during pressure distribution piping installation in the rock bed. C. Final inspection to verify final cover depths and to verify that all pump station (where required) components are functional and comply with codes. 5.
