GENER.AL CONTRACTOR: SEPTIC CONTRACTOR:
SITE EVALUATOR: S-P Testing REPORT DATE: February 4, 1998
The City of Orono has Approved your on-site syste�design as of February 9, 1998
(approved-disapproved) (date)
with die f 'ng conune ts:
' �
THIS IS NOT A PERMIT. This is a design a f r ich must acco th it pl . A permit must
be issued to a licensed septic contractor pri insta ation. A list of cu e ic ept' contractors is
enclosed.
NOTICE TO INSTALLERS: Any changes to the approved plans and s cs m ve ior 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.

940 So. Brown Rd.
Orono, Henn. Co., MN
This site has an existing on-site sewage treatment system which is classified as failed
due to not meeting a 3' separation from the bottom of the system and the saturated soil.
The system was not installed in the area of the original Design completed by S-P
Testing, Inc. dated September 10, 1984. Approximately 75% of the system is out of the
area tested which indicated mottled soil at SB#5 at 34" below the ground surface. An
addition to the house is proposed which will require the system to be upgraded.
Soil borings completed in the area of#1, 2 & 3 found the mottled soil changed & at a
higher elevation than in 1984. This may be caused by the sandy soils in the soil profile
being saturated during a very wet period in the late 1980's.
This on-site sewage treatment system is designed for a Type 1, 5 bedroom home & 1
bedroom guest house in the bam totaling 6 bedrooms, in accordance with the Minnesota
Pollution Control Agency Chapter 7080 and tocal ordinances.
The soils on this site are SCS soils mapped - HbC - Hayden loam. The seasonally
saturated soils were located at 28" to 60" (mottled soil). Due to the seasonally saturated
soils, a Pressurized Mound System will need to be installed to treat septic effluent. The
bottom of the treatment area must be located at least 3' above the saturated soils.
The soils at a depth of 12" have a percolation rate averaging 12.6 mpi.
1
.
The existing tanks may not be water tight and if not abandon, pump and fill with soil.
The pumping chamber and 2nd tank may be newer and may be used if the flow line is at
an adequate elevation and water tight. If the 2nd and 3rd tanks are water tight with the
1st tank abandoned, an additional 1000 gallon tank may be added and a new pumping
chamber totaling 3-1000 gallon holding tanks and 1-1500 gallon pumping chamber which
is required. 2-1000 gallon hotding tanks will need to be installed at the bam and flow
gravity to the pumping chamber at the house. The supply line will need to be insulated
in areas of winter travel.
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.
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 tumed over,
just break up the sod, be sure not to over work.
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.
With proper installation and maintenance, this system should have no problem in
treating septic effluent effectively.
2
. ,
Nothing other than human waste, toilet tissue, laundry, showers, water softener etc.
shoutd be disposed of into the septic tanks. Iron filters must be diverted out of the
system. 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.
