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 (1-3):
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 location,design and construction standards of the current Orono
Municipal Code but does meet the three foot separation requirement or two foot requirement for systems installed 1996 or earlier,and
which is not failing or an imminent threat to public health or safety.
d "NON-COMPLIANT SYSTEM" A prohibited ISIS;an ISTS located within a designated 100-year flood plain,any ISTS which may
or may not meet all the location,design,or construction 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): J
Tinspection 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 ).
Make sure septic tanks are pumped through manhole and not through white inspection pipes. This allows for the proper
cleaning. Keep water softner and iron filter discharge out of septic system to prolong life of drainfield. Ask pumper to test
alarm float to verify alarm is still working in your house. The alarm warns owner that septage is about to backup 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.
( UNFIELD CONDMON(8-10):
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. &Mrs. Tomhave:
An inspection of your septic system was conducted on April 12, 2000. The system was installed on
March 1, 1979 by Westonka Plbg. A summary of the inspection is below.
Septic Tank Condition
1. Pumpout not needed at this time.(Last Pumpout 5/18/98.)
The septic system is non-compliant due to a lack of a three foot separation distance between the bottom
of the drainfield to the seasonally high watertable. The three foot requirement is a State Code,not a City
Code. A soil boring was conducted to determine the depth of the seasonally watertable. The septic
system must be replaced by December 31,2008.
Enclosed is a list of state licensed septic contractors who work in Orono on a regular basis. Also
enclosed is a fact sheet explaining how a septic system functions properly. Finally, an as-built drawing
is enclosed that shows the approximate location of the septic system.
If you have any questions regarding this report, please contact me at the City Offices at 249-4600.
Respectfully,
Chris Pence
On-Site Systems Manager

In the event this inspection report is used to satisfy the requirements for a mortgage or other transfer of property,be
advised that this report does no guarantee or certify the existing system will continue to function properly,but is
merely an opinion of the adequacy of the system under current conditions based on the available information.
This report must be kept on the premises with the system location and pumping records.

THIS IS NOT A PERMIT. This is a design approval form which must accompany the site plan. A
permit must be issued to a licensed septic contractor prior to installation.
NOTICE TO INSTALLERS: Any changes to the approved plans must have prior approval of the
inspector (952-249-4600) Call for inspection 24 hours in advance.
ALL DRAINFIELD AREAS MUST BE FENCED OFF prior to building site excavation and
fencing must remain in place until final site grading. Approval to pour footings will not be granted
until the Inspections Department has verified the primary and alternate sites are protected.
NO VEHICULAR TRAFFIC OF ANY KIND is allowed within 20'of tested drainfield sites ever.
ACCEPTED X DENIED By the City of Orono subject to existing regulations and the
following conditions:
�JCOOir maxde5',g�
1) Pump and fill existing tanks. 3
2) 1.5' soil on top of mound, 1' soil on sides of mound.
3) Sand placement must follow design.
4) Alarm must be placed inside house.
5) Keep all water softner and iron filter discharge out of septic system.
6) A variance to be within 10 feet of property line and 10 feet to driveway is granted.

The existing on-site sewage treatment system is located in the construction limits for
State Highway 12. The existing tanks may be used if water tight.
This on-site sewage treatment system is designed for a Type 1, three bedroom home,
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
14" to 20" (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 20.0 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.
1
All neighboring wells are located greater than 75' 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.
