City Ordinance 199 requires that each existing on-site sewage treatment system in Orono be inspected every two years.
The on-site sewage treatment system at the above address has been inspected and appears to fall into the categories checked below.
SYSTEM CONFORMITY (i-3): �
1 "CODE SYSTEM" An ISTS which meets all the location,design and construction standards of the current Orono Municipal Code.
2 "COMPLIANT SYSTEM" An ISTS which does not meet all the locadon,design and construction standazds of the current Orono
Municipal Code but does meet the three foot separation requirement or two foot requ'uement for systems installed 1996 or earlier,and
which is not failing or an imminent threat to public health or safety.
( 3 J'`NON-COMPLIANT SYSTEM" A prohibited ISTS;an ISTS located within a designated 100-year flood plain,any ISTS which may
�Jor may not meet all the location,design,or conshvction standards of the current Orono Municipal Code and which is failing for any
reason;and any ISTS with less than three feet of unsaturated soil or sand between the distribution device and the limiting soil characteristics.
TANK CONDITION(5-7):
Tank inspection indicates:
5 Pumpout not needed at this time.
�6�Septic tanks must be pumped out this year (city code recommends tanks to be pumped out once every 3 years.
`'� Tank was last pumped �7���i'� 1 ).
Make sure septic tanks are pumped throu�h manhole and not throu¢h white inspection pipes. This allows for the proper
cleaning. Keep water softner and iron filter dischar¢e out of septic svstem to prolon¢life of drainfield. Ask pumper to test
alarm float to verifv alarm is still workin¢in vour house. The alarm warns owner that seata¢e is about to backua into basement.
7 Inspection risers missing-tanks could not be inspected. Inspection risers(4"dia.pipe)must be installed in each tank. If
tanks have not been pumped out within the last three years,they should be pumped out now.
DRAINFIELD CONDITION(8-101:
� Drainfield is dry,no surfacing evident.
9 Some evidence of surfacing,not critical yet.
10 Drainfield is saturated and visibly discharging untreated effluent to the surface. Contact the City Inspector
immediately.Repairs must be completed within 90 days.

Dear Mr. Brooks:
An inspection of your septic system was conducted on Jul� 12. 2UU0. A summary of the inspection
is below.
Septic Tank Condition
1. Pumpout not needed at this time.
The sepric system is non-compliant due to a lack of a three foot separation distance between the bottom
of the drainfield to the seasonally high���atertable. The three I�oot requirement is a State Code,not a City
Code. A soil boring was conducted to determine the depth oC the seasonally watertable. The septic
system must be replaced by December 31, 2007.
Enclosed is a list of state licensed septic contractors �vho ��or� in Orono on a regular basis. Also
enclosed is a fact sheet erplaining how a septic sti�stem functions properl��. Finally, an as-built drawing
is enclosed that shows the approximate location of the septic s�stem.
If you have any questions regarding this report, please contact me at the Ciri Oftices at 249-4600.
Res ectfull

Orono, Henn. Co., MN
This site has an existing failed system which is less than 3' from the saturated soils and
does not meet the wetland setback.
This on-Site Sewage Treatment System is Designed for a Type 1, four bedroom home
designed in accordance with the Minnesota Pollution Control Agency Chapter 7080 and
local ordinances.
The soils on this site are SCS soils mapped - HcC2 - Hayden clay loam. The seasonally
saturated soils were located at 26" to 38" (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 10.1 mpi.
A pumping chamber will need to be installed to lift the effluent to the treatment area.
Two pumping chambers will be needed. One will pump to the top of the hill to a
distribution box or drop box and flow gravity through a 4" diameter pipe to a second
pumping chamber located at the mound site which will pump to the mound. The power
supply and switches must be located outside the manhole and pumping chamber in a
weather proof enclosure. A waming 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 tumed over,
just break up the sod, be sure not to over work.
1
, ,
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 otf before construetion. 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 gray water(laundry, showers, etc.) human waste &toilet tissue
should be disposed of into the septic tanks. Garbage disposals are not reoommended,
due to adding more solids &fine solids passing through to the system. Excessive
amounts of soaps, cleaning agents &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.
