The on-site sewage treatment system at the above address has been inspected and appears to fall into the category
checked below.
(This is � an existing system [ ] new construction)
SYSTEM CONFORMITY (1-3):
1 "CODE SYS7EM"-A system which meets all the location, design, and construction standards of the current City
Codes, and Which is operating satisfactorily by treating and disposing of the entire current sewage input
without discharging any pollutants into ground or surface waters.
2 "CONFORMING SYSTEM"-A system which does not meet all the location, design, and construction standards of the
current City Codes, but was installed according to the code in effect at the time of installation, and uhich
is operating satisfactorily by treating and disposing of the entire current sewage input without discharging
any pollutants tnto ground or surface waters.
3 "NON-CONFORMING SYSTEM"-A prohibited system; a system located within a designated 100-year floodplain; any
system which may or may not meet all the location, design, and construction standards of the current City
Codes and which ts failing for any reason; and any system with less than 3 feet of unsaturated soil or sand
between the distribution device and the limiting soil characteristics.
(The limiting soil characteristic [ 7 has or ,�]–has not been identified at this time. If the limiting soil
characteristic has not been identified, this classtfication may be subject to revision.)
TANK CONDITION (5-10):
Tank inspection indicates:
5 Pumpout not needed at this time.
6 Solids accumulation in tanks indicates they should be pumPed out this year to help prevent future problems.
7 Solids accumulation in tanks is at a critical level. Tanks should be pumped out as soon as possibte.
`� � System is discharging to the surface. Tanks must be pumped out within 48 hours to eliminate surface dischar�e.
�(/ Inspection risers missing-tanks could not be inspected. Inspection risers (4" dia. pipe) must be installed in each
f\ tank at next pumpout. !f tanks have not been pumped out within the last three years, they should be purtiped
out now. —
10 Inspec t e is located directly over tank baffle (does not give accurate measurement of solids accumulation).
If tanks have not been punped out within the last three years, they should be pumped out now.
DRAINFIELD CONDITION (11-14):
Drainfield inspection indicates:
11 Drainfield is dry, no surfacing evident.
12 Some evidence of surfacing, not critical yet.
13 Drainfield is saturated and visibly discharging untreated effluent to the surface. Contact the City Inspector
immediately. Repairs must be completed within 90 days.

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 •- HbC - Hayden loam. The seasonally
saturated soils were located at 22" to 34" (mottled 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 5.0 mpi.
A pumping chamber will need to be installed to lift the effluent 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 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.
All neighboring wells are located greater than 100' away from the proposed treatment
area. The parcel to the south has city water.
1
. �
Keep ail 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 human waste, toilet tissue, laundry, showers, water softener etc.
should be disposed of into the septic tanks. Iron filters must be diverted out of the
system. Garbage disposals are not recommended, due to adding more solids & fine
solids passing through to the system. Excessive amounts of soaps, cleaning agents 8�
chlorine agents may kill the bacteria needed to treat septic effluent. Additives are not
recommended. Recommend to pump & clean your tanks through the manhole by a
certified pumper every 2 years. Check with your pumper to set up a schedule.
