This on-site Sewage Treatment System is partially designed for a Type 1,five-bedroom home in
accordance with the Minnesota Poilution Control Agency Chapter 7080 and local ordinances.
Once the house size,location and septic primary and future sites are chosen this design can be completed.
The seasonally saturated soils were located at 16"-24"(mottled soil). Due to the seasonally saturated soils,
a presswized Mound System will need to be installed to treat septic ei�luent.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 8 MPI.
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 a light and sound device;this is in case of a pump failure.
Use 7/32 inch perforations on the laterals.
The existing tank must be abandoned.All tanks must be deeper than two feet below grade or they need to
be insulated and as filter needs to be installed on the second tank. Clean outs must be installed on the end of
the laterals for maintenance.
Keep all heavy equipment off of the proposed treatment areas before and after construction. The
treatment area must be fenced off before construction begins.This Design is not valid&the System
will need to be relocated if failure to protect the areas proposed for the On-Site Sewage Treatment
systems occurs.
Nothing other than gray water,(laundry,showers,ect.)human water&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.

3. ABSORPTION AREA SIZING
Note:Mound setbacks ore measured from the Absorption Area.
A. Calculate Absorption Width:Bed Width (2.6)X Mound Absorption Ratio (1.F)=Absorption Width
10.0 ft X 2.00 = 20.0 ft
B. For slopes from 0 to 1%, the Absorption Width is measured from the bed equalty in both directions.
Calculate Absorption�dth Beyond the Bed:Absorption Width (3.A)-Bed�dth (2.6)-2= Width beyond Bed
( N/A ft - N/A ft) = N/A = N/A ft
C. For slopes>1%,the Absorption Width is measured downhill from the upstope edge of the Bed.
Calculate Downslope Absorption Width:Absorption�dth (3.A) -Bed Width (2.6)=ft
20.0 ft - 10.0 ft = 10.0 ft
