GENERAL CONTRACTOR: SEPTIC CONTRACTOR:
SITE EVALUATOR: S-P Testing REPORT DATE: December 1 , 1997
Approved January 28, 1998
The City of Orono has your on-site system design as of
(approved-disapproved) (date)
Variances for a 57' setback from a well, a 13' setback from
with dle following corrunents:
a property line, and a drainfield location on slopes exceeding 6� are
granted due to the absence of other sites on the property.
THIS IS NOT A PERMIT. This is a design approval form which must accompany the site plan. A permit must
be i;�sued 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 �nal site grading. Approval to pour footings will not be granted until tlie 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.

#70 Myrtlewood Rd.
Orono, Henn. Co., MN
This site has an existing on-site sewage treatment system ctassified as faifed due to not
meeting the 3' separation from the bottom of the system and the saturated soil. The
system is also surface discharging at this time which is classified as an imminent health
hazard and must be repaired or disconnected within 10 months.
This on-site sewage treatment system is designed for a Type 1, three bedroom home, in
accordance with the Minnesota Pollution Control Agency Chapter 7080 and local
ordinances. Approval will be needed for the existing well to be 57' from the system.
Approval will also be needed for the system to be 13' from the north property line and on
a 10% to 12% slope, 6% is required.
The existing tanks will need to be abandoned, pumped and filled with soil if not water
tight. The new tanks will need approval for a 50' setback from the wetland.
The soils on this site are SCS soils mapped - HbC - Hayden loam. The seasonally
saturated soils were located at 18" & 24" (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 13.0 mpi.
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 waming device must be installed with a light
and sound device, this is in case of a pump failure. Insulate the supply line through the
driveway.
1
( �
The manifoid 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.
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.
