GENERAL CONTRACTOR: Bruce Bren SEPTIC CONTRACTOR:
SITE EVALUATOR: S-P Testing REPORT DATLsarch 20, 1994
The City of Orono has Approved your on-site system design as of July 19, 1994
(approved-disapproved) (date)
with the following comments: The subdivision file indicates that a 50 ' setback is
required from both primary and alternate drainfield sites due to steep
slopes . The site survey indicates a 37 ' setback to the swimming pool .
The pool must be either relocated or removed to prevent drainage problems .
THIS IS NOT A PERMIT. This is a design approval form which must accompany the site plan. A permit must
be issued to a licensed septic contractor prior to installation. A list of currently licensed septic contractors is
enclosed.
NOTICE TO INSTALLERS: Any changes to the approved plans and specs must have prior approval of the
Inspector (473-7357). Call for inspections 24 hours in advance.
ALL DRAINFIELD AREAS MUST BE FENCED OFF prior to building site excavation and fencing must remain
in place until final site grading. Approval to pour footings will not be granted until the Inspections Department
has verified that primary and alternate sites are adequately protected.
NO VEHICULAR TRAFFIC OF ANY KIND (cars, trucks, earth moving equipment, etc.) is allowed within 20'
of tested drainfield sites either before or after system construction. Compaction of these areas could render them
unusable prohibiting the timely completion and or limiting the long term use of the property.
A site copy will be available at the City Offices for the septic contractor.

2 Acre Sub-Division
Woodhill Ridge, Outlot B
Orono, Henn. Co. , MN
This system is Designed for a Type 1, Five 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 - KkC - Kilkenny
loam. A seasonally high water table was located at 60" , 66" , 74" ,
78" & 90" , (mottled soil ) . The bottom of each trench must be located
at least 3 ' above the seasonally high water table. A standard trench
system can be installed.
The soils at a depth of 24" & 30" in Percolation test holes #1 through
#5 have a percolation rate averaging 24 . 0 min/inch and are adequate
for treating septic effluent. Percolation test hole #6 failed at
240 . 0 min/inch and the system can not be located in this area.
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 are a 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.
Recommend to pump the septic tank every year if there is only 1 tank
& every 2 years if there are 2 tanks .
