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 KIND (cars, trucks, earth moving equipment, etc.) is allowed

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, five
bedroom home in accordance with the Minnesota Pollution Control
Agency Chapter 7080 and local ordinances .
The soils on this site are SCS soils mapped - HbB - Hayden loam.
A seasonally high water table was located at 22" to 34" , (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.
The soils at a depth of 12" have a percolation rate averaging
3 . 1 min/inch.
This site has an existing failing system due to fill soils & a
high water table. The existing tanks consist of 2-1000 gallon
capacity. The tanks may be used upon approval by the local
Inspector if they are solid.
A pumping chamber will need to be installed to lift the effluent to the
treatment area.
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.
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 75 ' 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. Additives must not be used,
they may cause harmful damage to your septic system. Recommend
to pump your tank every year if you have 1 tank & every 2 years
if you have 2 tanks .
