This system is designed for a:Type 1, five bedroom home and in accordance
with the Minnesota Pollution.Control Agency standards'.WPC 40 and local
ordinances.
The soils on this -site are typical of SCS soils mapped - L+B - LeSueur loam
boardered by - Ha - Hamel loam. A seasonally high water table was located
at 22", 26", 30", & 42", (mottling). Due to the seasonally high water
table, a pressurized mound sybtem will need to be installed.' The bottom of
the rock bed must be located at least 3' above the seasonally high water
table.
The soils at a depth of 18" have a percolation rate averaging 5.4 min/inch
and are adequate for treating septic effluent.
A pumping chamber will need to be installed to lift the effluent to the
treatment area.
The manifold and supply line pipe must have back drainage to the pumping
chamber. The distribution pipes shall have their ends capped. Be sure
the rock and sand fill material .are clean. The sod layer below the
entire mounded area must be turned over, just break up the sod, be sure
not to over work.
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 are a good method).
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 pcesible. The treatment area shoui.3 be
marked off before construction.
With proper instal',�tion and maintenance, this system should have'no
problem'in treating septic effluent effectively. '
It is recommended that the septic tanks be pumped every 2 years.
