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 - LrB - Lester loam.
A seasonally high water table was located at 18" to 32" (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
8.1 min/inch.
A pumping chamber will need to be installed to lift the effluent
to the treatment area.
The manifold anO? 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 100' away from ;:he
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 propcsed 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. Smaller amounts of laundry
soaps, dish soaps, cleaning agents, etc. are better for the system.
Antibacterial soaps & chlorine agents may kill the bacteria needed
to treat septic effluent properly. Additives are not recommended,
they may cause harmful damage to your system. Recommend to pump
& clean your tanks by a certified pumper every year if you have
1 tank & every 2 years if you have 2 tanks to insure proper
maintenance.

A. Determine pump capacity:
Gravity Distribution
1. Minimum suggested is 600 gallons per hour (10 gpm) to stay ahead of
water use rate.
2. Maximum suggested for delivery to a drop box of a home system is 2,700
gallons per hour (45 gpm) to prevent build-up of pressure in drop box.
Pressure Distribution
3. a. Select number of perforated laterals
b. Select perforation spacing = ft.
c. Subt 2 ft. from the rock layer length.
Uns
-2ft.=moi _ft.
d. Determine the number of spaces between perforations.
Length pert. spacing = _ - ft. - ft. _ a- spaces

13. Determine head requirements:
1. Elevation difference between pymp and point of discharge.

2. If pumping to a pressure distribution system, add five feet for pressure
required at manifold

3. Friction loss
a. Enter friction loss table with gpm and pipe diameter.
Read friction loss in feet per 100 feet from table.
F.L. - D.6 ft./100 ft of pipe
b. Determine total pipe length from pump to discharge
point. Add 25 percent to pipe length for fitting
loss, or use a fitting loss chart. Equivalent pipe
length -1.25 times�ipe length =
�_ x 1.25 = _�_ feet
c. Calculate total friction loss by multiplying
friction loss in ft/100 ft by equivalent pipe length.
Total friction loss = t_ x�� +100 = -- feet
4. Total head requir-_,d is the sum of elevation difference,
special head requirements, and total friction loss.
