�K��7'ON SITE AT A L L TIM ES
CITY pF pRONp
This site has 2 possible areas to locate a new on-site sewage trea#ment system. The
1st site is located in the northeast corner of the lot. This site has fill 8� compacted soil &
woufd onty be adequate for a 2 bedroom home. The 2nd site is located at the south
end of the property. This site will need a mound system with a 50' setback from the
wetland. The City wi{I allow 26'.
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 a LrB - Lester foam, The periodically saturated soils were
I bcated at 12" to 20" (redox features). Due to the seasonally saturated soils, a
Pressurized Mound System will need to be installed to treat septic effluent. The bottom
of the rock must be located at least 3' above the saturated soils.
The soils at a depth of 12" have a percolation rate of 9,9 mpi. �RONp COPy
A pumping chamber wilf need to be installed to lift the effluent to the treatment area.
The power supply and switches must be tocated outside the manhole and pumping
chambEr in a weather proaf enclosure. A warning device must be installed with a light
and sound device, this is in case of a pump failure.
The manifald 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.
OkONO CQFY 1 ? !S SYSTEM IS DESIGNED FOR
�BE�ROOMS. ANY INCREASE{N NUMBER
OF 8�(iR00MS W�WOATES IH{S ti�Sl�
The supply line will need to be a directional bore. The supply line will have 50' of
drainback at the mound.
Insulate the first 20' of the supply line from#he tank.
The existing tanks will need to be abandoned, pumped 8� fill with soil.
Due to limited space, recommend Iow water use facilities be installed. Low flush toilets,
shower heads, etc.
The tanks witl need to be high water table Iow profile.
If the tanks have less than 2' of cover, the lids, risers & maintenance hole covers must
be insulated to a value of R10.
Cleanouts for each later must be installed & be accessible from finish grade in an
irrigation box with a ball valve.
All neighboring wells are located greater than 100' away from the proposed treatment
area.
If a garbage disposal is used, an effluent screen will be needed in the 2nd tank.
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 wifl need to be relocated if failure to protect the areas
proposed for On-Site 5ewage Treatment occurs.
2
NLANAGEMENT PLANS•
The tanks need to be pumped every 2 years. Check with your pumper to set up a
schedule.
System inspected for wet areas by owner & or Inspector as determined by the local unit
of government.
Any other requirements as determined by the local unit of government
With proper installation and maintenance, this system should have no problem in
treating septic effluent effectively.
Nothing other than human waste, toilet tissue, laundry, showers, water softener etc.
should be disposed of into the septic tanks. Recommend Iron filters be diverted out of
the system. Recommend to divert the water softner also if the iron filter is diverted.
Garbage disposals are no# recommended, due to adding more solids &fine solids
passing through to the system. Excessive amounts of soaps, antibacterial soaps,
cleaning agents, shower cleaners used every shower & chlorine �gents may kill the
bacteria needed to treat septic efftuent. Additives are not recommended. Recommend
laundering be limited to 3 to 4 loads per day.

The site has 2 possible areas to locat�• a ne�a On-Site Sewage Treat�ent
System. The lst site is located i.z the northeast lot corrier . This
site has fill soil & compacted �oil and �aould only be adequate for
a 2BR home, Pressurized Mound & would not meet State & local code .
The 2nd site is located at the south e:zd of the property. This
site would need a Pressurized Mound System and would need to be
less than 75 ' from a wetland . This site ��ill need to �e approved
by the City Inspector .
This On-Site Sewage Treatment System is Designed for a Type 1 , three
bedroom home in accordance with the Minnesota Pollution Control
Ac�ency Chapter 7080 and local ordinances .
The soils on this site are SCS soils mapped - LrB - Lester loam.
A seasonally high water table was located at 12" to 20" , (mottled
soil ) . The bottom of the rock bed must be located at least 3 '
al�ove the seasonally high water table .
The soils at a depth of 12" have a �ercol�tion rate averaging
9 . 9 min/inch and are adequate for treating septic effluent .
Due to the limited space , recommend low water use facilities be
installed , 1 . 5 qal . flush toilets , shower heads , etc .

chamber . The distribution pipes shall have their ends capped. �e sure
the rock and sand fill material are clean. The sod layer below the
entire mounded area must he turned over , just break up the sod , he sure
not to over work.
The power supply and switches must be located outside the manhole and
pumping chamb�r in a weather proof enclosure . A warning device must
be installed with a light arid sound �evice , this is in case of a pump
f_ailure . Mercury floats are a good method .
The supply line will need to be installed around the east end of
excavated ditch within 5 ' of the property line . Due to the high
water table , the supply line will need to be installed shallow
and be insulated to prevent freezing . Only the manifold and a
small section of the supply line will have drain back. Recommend
to add 12" to 18" of fill to cover the pipe north of the excavate�
ditch near the east property line .
The existing tanks are block type and will need to be abandoned ,
pumped & filled with soil .
�11 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
