This on-site sewage treatment system is designed for a church with 150 members at
.14 gal/member = 21 gal/week,2 weddings per week, one on a Saturday and one on
Sunday with no receptions for 150 people at 2.5 gal/each = 375 gal/day x 2 days = 750
gal/week, a caretaker house with 1 bedroom at 150 gal/day = 1050 gal/week & 2
meetings/week with 25 people at 2.5 gal/person x 2 meetings = 125 gal/week in
accordance with the Minnesota Pollution Control Agency Chapter 7080 and local
ordinances. The total water use/week = 1946 gallons divided by 7 days = 278 gal/day.
To allow for future growth, the system is designed for 450 gal/day, typical of a 3
bedroom home.
The soils on this site are a clay loam. The seasonalfy saturated soils were located at
20" to 38" (mottled soil - 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 5.7 mpi.
The existing tanks will need to be abandoned, pumped and filled with soil. 2-1000
gallon capacity tanks will need to be installed at the church & 1-1500 gallon dual
chamber at the caretaker house. The fianks will flow gravity to the 2000 gallon pumping
chamber that will pump using a timer 4 times a day to the system. The larger lift station
will allow for 3 day peak storage.
1
,, � ,
A pumping chamber will need to be installed to lift the effluent to the treatment area.
The power suppiy 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 ctean. The sod layer below the entire mounded area must be turned over,
just break up the sod, be sure not to over work.
Recommend to insulate the supply line from the tanks at the church to the pumping
chamber.
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 praper 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 not 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 agents may kitl 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.
