Orono,Hennepin County
This on-site Sewage Treatment System is partially designed for a Type l,five-bedroom home in
accordance with the Minnesota Pollution 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. There may be more sites available.
The periodically saturated soils were located at 18-30 Inches(mottled soil). Due to the
periodically saturated soits,a pressurized mound system will need to be installed to treat the
septic ef�7uent.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 3 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 uerforations on the laterals.
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 tank s every two years.

10.0 ft X 2.0 = 20.0 ft
B. For slopes>1�,the Absorption Width is meawred downhill from the upslope edge of the Bed.
Calculate DoNd�slq�e Absorption Width:Absorption Width (3.A)-Bed Width (2.6)=ft
20.0 ft - 10.0 ft = 10.0 ft
