ALL DRAINFIELD AREAS MUST BE FENCED OFF prior to building site excavation and fencing must remain in place until final site grading. Approval to pour footings will not be granted until the Inspections Department has verified the primary and alternate sites are protected.

Orono,Hennepin County This on-site Sewage Treatment System is designed for a Type 1,five-bedroom home in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The seasonally saturated zone is present at 14"-18"(mottled soil). Due to seasonally saturated soils,a pressurized Mound System will need to be installed to treat septic effluent. The bottom of the treatment area must be located at least 3'above the saturated soils. All neighboring wells are greater than 50 feet deep and 50 feet from proposed treatment areas. The soils at a depth of 12"have a percolation rate averaging 9 MPI. 7/32 perforations are to be used in the laterals. A 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. Septic system should be fenced off 20'away from proposed and future systems before construction begins. Keep all heavy equipment off of the proposed treatment areas before,during and after construction The area around both sites must be fenced off by the contractor before any construction begins This Design is not valid and the System will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. 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 I tank every two years for two tanks.

The mound must be carefully constructed to provide adequate sewage treatment. Mound failures have usually been traced to improper construction practices.
