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

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 which is classified as failed
due to not meeting a 3' separation from the bottom of the system and the saturated soil.
The system is surface discharging 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, four bedroom home, in
accordance with the Minnesota Pollution Control Agency Chapter 7080 and local
ordinances.
Approval will be needed from the local official to be 60' from the wetland with the on-site
sewage treatment system.
The soils on this site are SCS soils mapped - HcC2 - Hayden clay loam bordered by -
Ha - Hamel loam. The seasonally saturated soils were located at 12" & 18" (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.
Due to the mound location on the slope, an Interceptor Drain will need to be installed to
divert the drainage upslope of the system.
The soils at a depth of 12" have a percolation rate averaging 30.4 mpi.
1
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 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 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 2 years. Check with your
pumper to set up a schedule.
