KLLP THiS PLAN SET ON SITE AT ALL TlMES
This site has an existing on-site sewage treatment system which is classified as non-
compliance by the City of Orono.
This on-site sewage treatment system is designed for a Type 1, 6 bedroom home & 1
bedroom guest home (garage) totaling 7 bedrooms, in accordance with the Minnesota
Pollution Control Agency Chapter 7080 and local ordinances.
The soils on this site are a clay loam. The seasonally saturated soils were located at
16" to 26" (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 rock must be
located at least 3' above the saturated soils.
The soils at a depth of 12" have a percolation rate of 40.0 mpi.
The existing tanks may be used if water tight and upon approval from the City
Inspector.
The iron filter must be diverted out of the system.
The supply line from the guest house will need to be added if that system is classified
as non-compliance.
1
„ �
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.
Recommend directional boring for the supply line due to the pool &trees in the area.
The manifold and supply lin� 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 su�e not to over work.
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 eftluent 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 agertts, shower cleaners used every shower& 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. Recommend laundering be limited to 3
to 4 loads per day.

but no faster than the rate at which effluent will flow out of the
distribution device.
B. Pressure distribution
See pressure distribution work sheet

2. Enter Figure E-9 with gpm(lA or B)and pipe diameter(Cl).
Read friction loss in feet per 100 feet from Figure E-9 Speciai Head Requirements
