reports are not considered approved unless accompanied by the "City of Orono Septic
System Approval" cover sheet signed by the City Inspector.
4. The following inspections will be required for all septic systems:
A. Pre-installation site inspection to include inspector, installer, and general contractor.
B. Tank installation prior to covering.
C. Drainfield trench installation prior to covering. For mounds, inspection is required
after rough-up but prior to sand placement (sand will be jar tested for silt content),
and again during pressure distribution piping installation in the rock bed.
D. Final inspection to verify proper final cover depths and to verify that all pump station
(where required) components are functional and comply with codes.
5. Individual holding MPCA Installer Certificate shall be present during inspections: A 24-
hour notice is required for all inspections.

GENERAL CONTRACTOR: SEPTIC CONTRACTOR:
SITE EVALUATOR: S-P Testing REPORT DATE: December 22, 1997
The City of Orono has Approved your on-site system design as of March 11, 1998
(approved-disapproved) (date)
with the following cominents: A staff variance is granted for the mound location on slopes
greater than 6% (the slope is 7%) .
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.

Orono, Henn. Co., MN
This site has an existing on-site sewage treatment system classified as failed due to not
meeting a 3' separation from the bottom of the system and the saturated soil. The
existing system is 2-1/2' deep with mottled soil found at 24" to 30" deep. To adequately
treat septic effluent, a new system will need to be installed.
This on-site sewage treatment system is designed for a Type 1, four bedroom home, in
accordance with the Minnesota Pollution Control Agency Chapter 7080 and local
ordinances.
The soils on this site are SCS soils mapped - LrB - Lester loam. The seasonally
saturated soils were located at 34" & 36" (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 4.1 mpi.
The existing 1 st tank is a block type and less than 50' from the existing well and will
need to be abandoned, pumped and filled with soil. The 2nd tank is a newer tank and
may be used if water tight.
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.
1
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.
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.
Nothing other than human waste, toilet tissue, laundry, showers, water softener etc.
should 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.
