Orono, Henn. Co., MN ZERP'!'WMAN UTONSITE ATALL TIMES
A Compliance Inspection was completed for the existing on-site sewage treatment
system located on this property for an addition to the home which includes 2 bedrooms.
The home now has 3 bedrooms. 'The existing system consists of 3-1000 gallon septic
tanks & a pressurized mound system with a 10' x 38' rock bed.
Soil borings #1, 2 & 3 found mottled soil (redox features) at 30" to 36" below the ground
surface. Boring #4 was completed through the mound which found the original soil at
elev.1010.7 & the bottom of the rock bed at elev.1011.7 which leaves 1' of sand below
the rock bed. Boring #5 was completed through the mound which found the original
soil at elev.1010.5 &the bottom of the rock bed at elev.1011.7 leaving 1.2' of sand
below the rock bed. This system is classified as in compliance with Minnesota Chapter
7080 rules. ORONO COPY
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 existing west end of the mound will need the loam topsoil fill removed to the
existing sand. An additional 10' x 24' rock bed will need to be installed with the upslope
edge of the rock bed having the original soil at elev.1010.7.
The existing tanks will need to be abandoned, pumped & filled with soil. The new tanks
will be installed at the excavated walkout for the home.
All property lines must be located prior to installation. THI SYS?E $1MGNED FOR
-,5—BEDROM ANY INC?EASE IN NUMBER
Of BEOROQM IWALIDATES THIS DESIGN.
ORONO COPY" 1
RECT NOV 14 2007
The soils at a depth of 12" have a percolation rate of 8.3 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.
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 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 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.

PUMP SELECTION PROCEDURE
1. Deterini ae pui-np capacity:
A. Gravity distribution
1. Minimum required discharge is 10 gpm
2. Maximum suggested discharge is 45 gpm. For other
establishments at least 10%greater than the water supply rate,
but no faster than the rate at which effluent will flow out of the
distribution device.
