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 functionarand comply with codes.
5. Individual holding MPCA Installer Certificate shall be present during inspections: A 24-
hour notice is required for all inspections.
NOTE: Applicant must initial all spaces. Fill in all appropriate blanks, check all appropriat
boxes.

SITE EVALUATOR: S-P Testing Inc REPORT DATE: May 16, 1997
The City of Orono has approved your on-site system design as of November 12, 1997
(approved-disapproved) (date)
with the following comments:
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.

Spring Hill Golf Club
Maintenance Building & Rest Area
Orono, Henn. Co., MN
These on-site sewage treatment systems are designed for a Golf Club maintenance
building with 20 employees at 15 gal/each day and a rest area with 150 golfers at 2
gal/each/day , totaling 300 gal/day each system, in accordance with the Minnesota
Pollution Control Agency Chapter 7080 and local ordinances.
The seasonally saturated soils were located at 18" to 40" (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 3.4 mpi in TH'S#1,2 & 3
(maintenance building) & 10.2 in TH's#7,8 & 9 (rest 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. An audio alarm & light must be installed with an
exterior light at the controls in case of a pump failure. There are 2 options for the
pumping chamber. The first is to use dual pumps with an alternating relay and the
second is to install a larger tank with a minimum of 3 days reserve storage.
An event counter& water meter must be installed at both sites.
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.
1
r
Due to the limited use during the winter season, the tanks must be insulated (top &
sides) to prevent freezing. Also recommend to pump the tanks at the end of the season.
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 gray water(laundry, showers, etc.) human waste &toilet tissue
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 year. Check with your
pumper to set up a schedule.
