This on-site Sewage Treatment System is designed for a Type Ithree-bedroom home in
accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances.
The periodically saturated soils were located at 26 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.
All neighboring wells are greater than 100' from proposed treatment areas.
The soils at a depth of 12"have a percolation rate averaging 3 MPI.
The existing septic tanks must be abandoned and one new 1250 gallon and 1000gallon septic
tanks need to be installed.
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 new 1300 gallon lift station 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.
Nothing other than Eray water,(laundrv,showers,etc.)Human water and toilet tissue
should be disposed of into the septic tanks.Garba�e disposals are not recommended.
Additives must not be used; thev may cause harmful dama�e to your septic svstem. It is
recommended that vou pump the taok everv vear for 1 septic tank,every two vears for two
septic tanks.
