Orono, MN
A compliance inspection was completed for the existing on-site sewage treatment
system located on this property. The system consists of 2-1000 gallon septic tanks
& 2 trenches 175' long each = 350 lin.ft., 1050sq.ft built in 1983 or a 5 bedroom
home.
Soil boring #1 found mottled soil (redox features) at 2.5' below the surface & the
bottom of the rock in the trench at 2.5' leaving no separation from the bottom of the
rock & redox features. Soil boring #2 found mottled soil at 2.5' & the bottom of the
rock at 2' leaving a .5' separation. This system does not meet compliance & is
classified as non-compliant under Minnesota Chapter 7080 rules. The City of Orono
requires the system to be upgraded within 3 years.
The tanks are old & will need to be abandoned pumped & filled with soil & a tank
abandonment report completed by a licensed contractor.
This onsite sewage treatment system is designed for a Type 1 system, Type 1, 5
bedroom home in accordance with the Minnesota Pollution Control Agency chapter
7080 & local ordinances.
The soils on this site are a clay loam. The seasonally saturated soil, mottled soil
(redox features) were present at a depth of 22" to 30". A pressurized mound system
will be installed. The bottom of the treatment area must be located at least 3' above
mottled soil.
A pumping chamber will need to be installed to lift the effluent to the treatment area.
The power supply & switches must be located outside the manhole & pumping
chamber in a weather proof enclosure. A warning device must be installed with a
light & sound device, this is in case of a pump failure.
The manifold & supply line must have back drainage to the pumping chamber. Be
sure the rock & sand fill material are clean. The sod layer below the entire mounded
area must be turned over, just break up the sod.
All property lines must be located prior to installation.
If the tanks have less than 2' of cover, the lids, risers & maintenance hole covers
must be insulated to a value of R70.
Cleanouts for each lateral with a sleeve must be insulated & be accessible from
finished grade in an irrigation box with a ball valve.
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
sites for new on-site sewage systems.
MANAGEMENT PLAN,
The tanks need to be maintained at a minimum of 1 time every 2 years, check with
your pumper to set up a schedule.
System inspected for areas by owner & or Inspector as determined by the local unit
of Government.
Any other requirements as determined by the local unit of Government.
With proper installation & maintenance, this system should have no problem in
treating septic effluent effectively.
Nothing other than human waste, toilet tissue, laundry, showers, water softners etc.
should be disposed of into the system. Recommend iron filters be diverted out of the
system. Garbage disposals are not recommended. 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 laundering be limited to 3 to 4 loads per day.

Septic System Management Plan
for Below Grade Systems
The goal of a septic system is to protect human health and the environment by Properly treating
wastewater before returning it to the mvioucuser. You, septic
organismssystem is designed to kill tanning
and remove pollutants before the water is recycled back inn our lakes, streams and
groundwater.
In This management plan will identify the operation and maintmance activities necessary to ensure
ng-term performance of Yom septic system. Some of these activities must be performed by you, the
hommwms,. Other tasks must be performed by a licensed septic maintains, m service provider.
However, it is YOUR responsibility to make aura all tasks get accomplished in a timely manner.
The University of Minnesota's Septic System Owner's Guide contains additional tips and
recommendations designed to extend the affective life ofyom system and save you money over time.
Proper septic system design, tnatal uffea, operation and maimeaance means safe and clean water!

These
your activities.
Identify the service intervals recommended by Yom system designer and Yom local government.
The tank easessment for you system will be the shortest interval of these three intervals. Yom
pumper/maintainer will determine if your tank needs to be pumped.
System Designer: check every �_tuonths
Local Government. check every months My tank needs to be checked

Seasonally or several time, per year
• Leaks. Check (listen, look) for leaks in toilets and dripping faucets. Repair leaks promptly.
• Surfacing sewage. Regularly check for wet or spongy soil amend you soil treatment area. If
surfaced sewage or strong odors are not corrected by pumping the tank or fixing broken caps and
leaks, call your service professional. Untreated sewage may make humans and animals sick.
• Alarms. Alarms signal when there is a problem; contact your maintainer any time the alarm
signal,.
• Lint filter. If you have a lint filter, check for lint buildup and clean when necessary. Consider
adding one after washing machine. .
• Effluent screen. If you do not have one, consider having one installed the next time the tank is
cleaned.
Annually
• Water usage rate. A water meter can be used to monitor Yom average daily water use. Compare
your water usage rate to the design flow of you system (listed on the next page), contact Yom
septic professional if Yom average daily flow over the course of a month exceeds 70% of the
design flow for Yom system.
• Caps. Make sure that all caps and lids are intact and in place. Inspect for damaged caps at least
every fall. Fix or replace damaged caps before winter to help prevent freezing issues.
• Water conditioning devices. See Page 5 for a list of devices. When possible, program the rechazge
frequency based on water demand (gallons) rather than time (days). Recharging too frequently
may negatively impact Yom septic system,
• Review you water usage race. Review the Water Use Appliance chart on Page 5. Discuss any

major changes with you puper/maintainer.
During each visit by a pumper/maintainer
• Ask if yourpumper/maintainer is licensed in Minnesota.

• Manhole lid. A riser is recommended if the lid is not accessible from the ground surface insulate
the tiler cover for frost protection
• Liquid level. Check to make sure the tank is not leaking, The liquid level should be level with the
bottom of the outlet pipe. (If the water level is below the bottom the e outlet pipe, the tank may
not be watertight. If the water level is higher than the bottom of the outlet pipe of the tank, the
effluent screen may need cleaning, or there may be ponding in the drainfield.)

• Event counter or run time. Check to see if there is an event counter or ran time log for the pump.
If there is one, calculate the water usage rate and compare to the anticipated average daily flow

Soil Treatment Area
• Inspection pipes. Check to make sure they are properly capped. Replace caps that we damaged.
• Surfacing of effluent. Check for surfaced effluent or other signs of problems.
• Gravity trenches and beds. Check the number of gravity trenches with ponded effluent. Identify
the percentage of the system in use. Determine if action is needed.
• Pressure trenches and beds - Lateral flushing. Check lateral distribution; if ckeanouts exist, flush
