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 retuming 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 malce 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 system design, installntion, operation nnd mainten�cnce means safe and clean water!

Keep this Management Plan with your Septic System Owner's Guide. The Septic S�stem Divner's Guide
includes a folder designed to hold maintenance records including pumping> inspectiAn and evaluation
reports. Ask your septic professional to also:
• Attach permit information, designer drawings and as-builts of yaur system, if they are available.

Homeowner Management Tasks
These operation and maintenance activities are your responsibility. 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 three intervals. Your
pumper/maintainer will determine if your tank needs to be pumped.
System Designer: check every 36 months
My tank needs to be checked
Local Government: check every 36 months
State Requirement: check every 36 months every 36 months
Seasonally or several times 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 around your soil treatment area. If
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.
• Efftuent screen. If you do not have one, consider having one added the next time the tank is
cleaned.
Annually
• Water usage rate. A water meter 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 70% 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 ivater 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 chait 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 111anhole. (NOT though a 4"
or 6"diameter inspection port.)
• Ask your pumper/maintainer to accomplish the tasks listed on the Professional Tasks on Paga q.

Professional Management Tasks
These are the operation and maintenance activities that a pumper/maintainer performs to help ensure
long-term performance of your system. Professionals should refer to the O/M Manual for detailed
checklists for tanks,pumps, alarms and other components. 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 TanWPump 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 works.
• 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 th� 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 eff luent. Check for surfaced effluent or other signs of problems.
• Lateral flushing. Check lateral distribution; if cleanouts exist, flush and c��an as needed.
• Ponding. Check for ponding. Excessive ponding in at-grade and mound beds indicates
problems.
All other components—inspect as listed here;
Squirt Height Apparatus with Gate Valve. Set Gate Valve to achieve even spray height.
