Lot 3 , Blk . 3 , Fox Bend
Orono , Henn. Co. , MN
This system is Designed for a Type 1, four bedroom home and in accordance
with the Minnesota Pollution Control Agency Chapter 7080 and local
ordinances .
The soils on this site are typical of SCS soils mapped - LrB - Lester
loam. A seasonally high water table was located at 18" , 20" , 22" ,
24" , 26" & 30" , (mottled soil ) . Due to the seasonally high water table,
a pressurized mound system 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 13 . 8
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 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.
Recommend to pump .the septic tank every year if there is only 1 tank
& every 2 years if there are 2 tanks . _
