This system is designed for a Type'TTT^three 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 • LrB ~ Lester loesi*
A seasonally high water table was located at 48", 54", & 56", (mottling).
The bottom of each trench must be located at least 3' above the seasonally high water table.
This site has an existing failing system. The system is old with clay tile
for distribution pipe and is located in soil with a seasonally high water
table less than 3'. The existing tank is too deep and will need to be
abandonded, pump & fill with soil.
A lift pump will be needed in the lower level.
The soils at a depth of 18" have a percolation rate averaging 10.2 min/inch
and are adequate for a standard treatment system installed shallow at 18" deep.
All neighboring wells are located more than 75’ away from the proposed treatment area.
Keep all heavy equipment off of the proposed treatment area before and
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.
It is recommended that the septic tanks be pumped every 2 years.
