This On-Site Sewage Treatment System is Designed for a Type 1,Tliree
bedroom home in accordance with the Minnesota Pollution Control
Agency Chapter 7080 and local ordinances .
The soils on this site are SCS soils mappec, - Lr13 - Lester loam. n
seasonally high wat�r tat�le was locat�d at 22" to 30" , (mottled
soil ) . Due to the seasonally high water table, a Pressurized r;ound
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 failing system due to a high seasonally
high water tahle & strong clay soils . mhE exi�ting tank ��ill need
to be abandoned, pumped & filled with soil .
The soils at a deptti of 12" have a �ercc,lation rate averaging
6 . 7 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 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 musi� be turned over, just break tap 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 .

�2)
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 there are 2 tanks .

This �On-Site Sewage Treatment System is Designed for a Type 1,Ttlree
bedroom home in accordance with the Minnesota Pollution Control
Agency Chapter 7080 and local ordinances . '
The soils on this site are SCS soils m�ppec� - LrB - Lester loam. A
seasonally high water table wa� locat�d at 22" to 30" , (mottled
soil ) . Due to the seasonally high water table, a Pressurized r;ouna
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 failing system due to a high seasonally
high water table & strong clay soils . '"hE exi�ting tank ��ill need
to be abandoned, pumped & filled with soil .
The soils at a depth of 12" ha�e a percalation rate ���eraging
6 . 7 min/inch and are ad�quate for treat�ng sEptic effluent.
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 ir. a �aeatht�r �r.00f 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.
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 there are 2 tanks .
