This on-site Sewage Treatment System is designed for a Type l,Five-bedroom home in accordance with
the Minnesota Pollution Control Agency Chapter 7080 and local ordinances.
The periodically sahirated soils were located at 12"-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 azea must be located at least 3'above the saturated soils.
The soils at a depth of 12"have a percolation rate averaging 3 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.
Use 7/32 inch perforations on the laterals.
All neighboring wells are greater than 100' from proposed treatment areas.
A 1300 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
encloswe.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 pumping chamber.
Keea all heavv eqniament off of the aroaosed treatment areas before,during and after construction.
The area around both sftes must be fenced off bv the contractor before anv construction beains.
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.

3• ABSORPTION AREA SIZING
Note:Mound setbocks are measured from the Absorption Area.
A. Calcutate Absorption Width:Bed Width (2.6)X Mound Absorption Ratio (1.f)=A6sorption Width
10.0 ft x 2.0 = 20.0 ft
B. For slopes>1%,the Absorption Width is measured downhill from the upstope edge of the Bed.
Calculate Downslope Absorption Wfdth:Absorption Wfdth (3.A)-Bed Width (2.B)=ft
20.0 ft - 10.0 ft = 10.0 ft
4. MOUND SIZING
A. Calculate C(ean Sand Lift: 3 feet minus Depth to Limiting Condition (1.C)=Clean Sand Lift (1 ft minimum)
3.0 ft - 1.0 ft = 2.0 ft Design Sand Lift(optional): �Z 0
B. Calculate Upslope Height:C[ean Sand Lift (4.A)+media depth (1 ft.)+cover (1 ft.)=Ups(ope Height
2.0 ft + 1.0 ft * 1.0 ft= 4.0 ft
