NOTICE TO GENERAL CONTRACTORS: Primary and alternate drainfield sites MUST be protected
prior to and after system installation to avoid compaction of the natural soil.
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 RIND (cars, trucks, earth moving equipment, etc.) is allowed
within 20' of tested drainfield sites either before or after system construction. This
applies to the lot you are working on and all adjacent lots. You could be held liable for
damaging sites on neighboring lots.
VEHICULAR TRAFFIC CAN CAUSE SOIL COMPACTION, RENDERING DRAINFIELD SITES UNUSABLE.
Evidence of traffic on drainfield sites may be cause for revocation of building permits.
Damaged alternate sites must be replaced before a Certificate of Occupancy will be issued.

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 .
The soils on this site are typical of SCS soils mapped - LrB - Lester
loam. A seasonally high water table was--located at 22" & 28" ,
(mottled soil ) . Due to the seasonally high water table, a Pressurized
Mound System will need to be installed. The bottom of the rock bed
must be located at least 3 ' above the seasonally high water table.
This site has an existing system which is located in strong clay soil
with a high water table. The existing tank or tanks are old & must
be abandoned, Pumped & filled with soil .
A variance will be needed ior a property line setback of 10 ' & a
10 ' setback from the existing garage, slab on grade.
•
The soils at a depth of 12k' have a percolation rate averaging 3. 5
min/inch and are adequate for treating septic effluent.
A pumping chamber will need to be installed to lift the effluent to the
treatment area.
The manifold and supply li a pipe must have back drainage to the pumping
chamber. The distributionlpipes 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.
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.
(Mercury floats are a good method) .
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.
Recommend to pump the septic tank every year if there is only 1 tank
& every 2 years if there are 2 tanks .
