Orono, Henn. Co., MN
This On-Site Sewage Treatment System is Designed for a Type 1, five bedroom home,
in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local
ordinances.
The soils on this site are SCS soils mapped - KkC - Kilkenny loam. The seasonally
saturated soils were located at 2-1/2' & 2'8" in th's #1, 2 & 3 (future site) which will
require a pressurized mound system & 5-1/2' & 6-1/2' in th's #4, 5 & 6, the proposed
site. The bottom of the treatment area must be located at least 3' above the seasonally
saturated soils. A Standard Trench System may be installed.
The soils at a depth of 12" in th's# 1, 2 & 3 have a percolation rate averaging 5.9 mpi.
The soils at a depth of 24" in th's#4, 5 & 6 have a percolation rate averaging 17.6 mpi.
All neighboring wells are located greater than 100' away from the proposed treatment
area.
Keep all heavy equipment off of the proposed treatment area before and after
construction. The treatment area should be marked off before construction. This
Design is not valid & the system will need to be relocated if failure to protect the areas
proposed for On-Site Sewage Treatment occurs.
1
With proper installation and maintenance, this system should have no problem in
treating septic effluent effectively.
Nothing other than gray water (laundry, showers, etc.) should be disposed of into the
septic tanks. Garbage disposals are not recommended, due to adding more solids &
fine solids passing through to the system. Excessive amounts of soaps, cleaning agents
& chlorine agents may kill the bacteria needed to treat septic effluent. Additives are not
recommended. Recommend to pump & clean your tanks through the manhole by a
certified pumper every 2 years. Check with your pumper to set up a schedule.
