1 "CODE SYSTEM" An ISTS which meets all the locntion,design and construction standards of the current Orono Municipal Code.
2 "COMPLIANT SYS'I'EM" 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 sepazation requirement or two foot requirement for systems installed 1996 or eazlier,and
which is not failing or an imminent threa[to public health or safety.

or may not meet all the location,design,or construction stan�vds of tlie current Orono Municipal Code and which is failiag for aay
reason;and any I5T5 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 tanl:s must be pumped out this year (city code recommends tanks to be pumped out once every 3 yeazs.

Make sure septic tanks are pumped throuEh manhote and not throueh white inspection aines. This allows for the uroaer
cleanine. Keep�vater softner and iron filter disch�r�e out of seatic svstem to urolong life of drainfield. Ask aumper to test
alarm float to verifv alarm is still working in your house. The alarm warns owner that septage is about to backup into basement.
7 Inspection risers missin�-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(8-10): ,�
8 Drainfield is dry,no surfacing evident.

most respects appears to be designed, located, and constructed in accordance with previous
codes and is functioning properly.
3 Non-Compliant System: System may or may not meet current City standards for design,
construction, or location, but is failing to properly treat and dispose of the current
input; and any system with less than three feet of vertical separation between the bottom of
the drainfield and the saturated soil level.

within three years, they should be pumped out and risers installed now.
90 Inspection pipe is located �over tank baffle-can not measure solids accumulation. If tanks
have not been pumped out within three years, they should be pumped out now.
10 One or more tanks are cesspools, which means the septic system is non-compliant.

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. This design is for an alternate site for this property.
The soils on this site are a clay loam. The seasonally saturated soils were located at
14" to 18" (mottled soil). Due to the seasonally saturated soils, a Pressurized Mound
System with 2 rock beds 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 rockbeds are 17'
apart which is the absorption width which classifies the system as standard. The
distribution pipe will be the same level.
Approval will be needed for the toe of the mound to be 15' from the right away.
The soils at a depth of 12" have a percolation rate of 12.0 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.
1
l �
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
bacter�a needed to treat septic efftuent. Additives are not recommended. Recommend
to pum� & 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
#0-�4 toads per day.
