Cologne, MN 55332
Location of proposed septic system site:
PID#3111823420012
4220 Chippewa Lane
Orono, MN 55359
This site is designed for Above Grade Mound System
The site must remain protected until construction begins.
(This is the responsibility of the owner and or General Contractor)
This site evaluation was evaluated on March 22, 2016. It is for a type one dwelling with
and estimated flow of 750 gallons per day. Soils information indicated a seasonal water
table at 26 inches. A Mound System will be required to meet the 3- foot separation from
the seasonal high watertable as required by MPCA Agency Rules and Standards, Chapter
7080, 81.
The Mound System design area is 42 feet wide with a length of 92 feet. Pin Flags have
marked the location of the soil borings, plus the boundary of the system.
The proposed system will require (1) 1500 gallon septic tank, (1) 1000 gallon septic tank,
and (1) 1500 gallon dosing tank. The tanks cannot be deeper than 4 feet from ground
elevation, and manholes must come to the surface, but be higher to not allow surface
water to enter manholes. The pump will need to be sized to deliver 36 gallons per
minute with a lift of 15 feet of total head. An effluent filter must be installed in the
second tank with an alarm system. The filter must be checked and cleaned on routine
, � �
basis—normal use will require the filter to be rinsed off twice a year(spring arid fall).
This is the responsibility of the systems owner.
The setback for the well from the septic system area must be a minimum of 50 feet for
both the septic tanks and the absorption area. The septic tanks will need to be at least 10
feet from the edge of the house and the absorption field must be 10 feet away from
property lines. It is the responsibility of the owner to identify the property
boundaries for designing and installing the septic system.
The septic system if properly installed and maintained should have no problems treating
effluent in the matter that it was designed for. Nothing other than human waste, toilet
tissues, shower, sink, dishwasher and laundry water should be drained to the septic tanks
and treatment field. If you have water treatment systems other than water softeners, in ex.
Iron filters, they should be diverted from entering the septic system.
Garbage disposals are not recommended, as they will add more solids to your septic tanks
and may allow fine particles to enter the treatment area and clog the system. Daily toilet
bowl cleaners, shower sprays (that are used after every shower), and excessive cleaning
agents may kill bacteria needed to treat septic effluent. Additives are not needed, and are
not recommended in properly mainta7ned septic system.
�
You should have your septic tanks pumped and inspected for proper maintenance
by a certified pumper every 2 years.
General
The soil conditions have been established at the test hole location only. There may be
variations in soil stratigraphy between and around the borings and interpolation and
extrapolation of the results is not warranted.

Septic System Management Plan
for Above 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 environment. Your septic system is designed to kill harmful
organisms and remove pollutants before the water is recycled back into our lakes, streams and
groundwater.
This management plan will identify the operation and maintenance activities necessary to ensure long-
term performance of your septic system. Some of these activities must be performed by you, the
homeowner. Other tasks must be performed by a licensed septic maintainer or service provider.
However, it is YOUR responsibility to make sure 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 effective life of your system and save you money over time.
Proper septic systen:design, installation, operation ajtd maintenance means safe c�ttd clean water!

Keep this Management Plan with your Septic System Owner's Guide. The Septic System <hvner's Guide
includes a folder designed to hold maintenance records including pumping, inspection and evaluation
reports. Ask your septic professional to also:
• Attach permit inforn�ation, designer drawings and as-builts of your system, if they are available.
• Keep copies of all pumping records and other maintenance and repair invoices with this document.
• Review this document with your maintenance professional at each visit;discuss any changes in product
use, activities or water-use appliances.

Homeowner Management Tasks
These operation and maintenance activities are yot�r responsibiliry. Use the chart on page 6 to track
your activities.
Identify the service intervals recommended by your system designer and your local government.
The tank assessment for your system will be the shortest interval of these tliree intervals. Your
pumper/maintainer will determine if your tank needs to be pumped.
System Designer: check every months
My tank needs to be checked
Local Government: check every months
State Requirement: check every 36 months
every 36 months
Seasonally or severai times per year
❑ I,eaks. Check (listen, look) for leaks in toilets and dripping faucets. Repair leaks promptly.
❑ Surfacing sewage. Regularly check for wet or spongy soil around your soil treatment area. [f
surfaced sewage or strong odors are not corrected by pumping the tank or fixing broken caps, 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
signals.
❑ 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 added the next time the tank is
cleaned.
Annually
❑ Water usage �•ate. A water tneter can be used to monitor your average daily water use. Compare
your water usage rate to the design flow of your system (listed on the next page). Contact your
septic professional if your average daily flow over the course of a month exceeds '�0% of the
design flow for your 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 recharge
frequency based on water demand (gallons) rather than time (days). Recharging too frequently
may negatively impact your septic system.
❑ Review your water usage rate. Review the Water Use Appliance chart on Page 5. Discuss any
major changes with your pumper/maintainer.
During each visit by a pumper/maintainer
❑ Ask if your pumper/maintainer is licensed in Minnesota.
❑ Make sure that your pumper/maintainer services the tank through the manhole. (NOT though a 4"
or 6"diameter inspection port.)
❑ Ask your pumper/maintainer to accomplish the tasks listed on the Professional Tasks on Page 4.

Professional Management Tasks
These are the operation and maintenance activities that a pumper/rnaintainer performs to /ielp ensure
long-term performance of your system. Professionals should refer to the O/M Manual for detailed
checklists for tanks,pumps, alarms and other compo�zents. Call 800-322-8642 for more details.
❑ Written record provided to homeowner after each visit.
Plumbing/Source of Wastewater
❑ Review the Water Use Appliance Chart on Page 5 with homeowner. Discuss any changes in
water use and the impact those changes may have on the septic system.
❑ Review water usage rates(if available)with homeowner.
Septic Tank/Pump Tanks
❑ Manhole lid. A riser is recommended if the lid is not accessible from the ground surface. Insulate
the riser 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 of the 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.)
❑ Inspection pipes. Replace damaged caps.
❑ Baffles. Check to make sure they are in place and attached, and that inlet/outlet baffles are clear
of buildup or obstructions.
❑ Effluent screen. Check to make sure it is in place; clean per manufacturer recommendation.
Recommend retrofitted installation if one is not present.
❑ Alarm. Verify that the alarm warks.
❑ Scum and sludge. Measure scum and sludge in each compartment of each septic and pump tank,
pump if needed.
Pump
❑ Pump and controls. Check to make sure the pump and controls are operating correctly.
❑ Pump vault. Check to make sure it is in place; clean per manufacturer recommendations.
❑ Alarm. Verify that the alarm works.
❑ Drainback. Check to make sure it is operating properly.
❑ Event counter or run time. Check to see if there is an event counter or run time log for the pump.
If there is one, calculate the water usage rate and compare to the anticipated average daily flow
listed on Page 2.
Soil Treatment Area
❑ Inspection pipes. Check to make sure they are properly capped. Replace caps that are damaged.
❑ Surfacing of effluent. Check for surfaced effluent or other signs of problems.
❑ Lateral flushing. Check lateral distribution; if cleanouts exist, flush and clean as needed.
❑ Ponding. Check for ponding. Excessive ponding in at-grade and mound beds indicates
problems.
