THIS IS NOT A PERMIT. Tl�is is a design approval form which must accompany the sitc 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 si[es either before or after system construction. Compaction of these areas could render them
unusable prohibiting the timely comple[ion and or limiting the long term use of the property.
A site copy will be available at the City Offices for the septic contrac[or.

Orono, Henn. Co., MN
This on-Site Sewage Treatment System is Designed for a Type 1, six bedroom home, in
accordance with the Minnesota Pollution Control Agency Chapter 7080 and local
ordinances. "
This site has an existing system classified as failed due to not meeting the 3' separation
from the bottom of the system to the saturated soils. To adequately treat septic effluent,
a Pressurized Mound System will need to be installed. The existing tanks may be used
upon approval by the local Inspector. The tanks must be water tight.
The soils on this site are SCS soils mapped - HcC2 - Hayden Loam. The seasonally
saturated soils were located at 16" to 26" (mott(ed 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 9.5 mpi.
A pumping chamber will need to be installed to lift the efftuent 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 lic�e pipe must have back drainage to the pumping chamber.
The distribution pipes shall have their ends capped. Be sure the rock and sand fifl
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.
1
Ail 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 8� clean
your tanks through the manhole by a certified pumper every 2 years. Check with your
pumper to set up a schedule.
