This system is Designed for a Ty e(l, five be^iroom home and in accordance
with the Minnesota Pollution Cor. rd^ Age^ii^jr^hapter 7080 and local
ordinances.
The soils on this site are typical of SCS soils mapped - HeB - Heyder
sandy loam. A seasonally high water table was located at 60" & 76",
(mottling). The bottom of each trench must be Icoated at least 3' above
the seasonally high water table. The alternate site will need to be
a pressurized mound system.
The soils at a depth of 30" have a percolation rate averaging 13.6 min/inch
and are adequate for a standard treatment system.
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 weather proof enclosure. A warning device must be
installed with a light and sound device, this is in case of a pump failure.
(Mercury floats area good method). The supply line pipe must have back
drainage to the. pumping chamber.
All neighboring wells are located more than 100' away from the proposed
treatment area.
Keep all heavy equipment off of the proposed treatment area before and
after construction as much as possible. The treatment area should be
marked off before construction.
With proper installation and maintenance, this system should have no
problem in treating septic effluent effectively.
r Recommend to pump the septic tank every year if there is only 1 tank:
' & every 2 years if there are 2 tanks.
