Septic System Mana ement 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 r cycled back into our lakes, streams and
groundwater.
This management plan will identify the operation and mai tenance activities necessary to ensure long-
term perfonnance of your septic system. Some of these activities must be performed by you, the
homeowner. Other tasks must be performed by a licen ed septic maintainer or service provider.
However, it is YOUR responsibility to make sure all tasks ge accoinplished in a timely manner.
The University of Minnesota's Septic System Owne 's Guide contains additional tips and
recommendations designed to extend the effective life of you system and save you money over time.
Proper septic system design, installation, operation and aintenance means safe and clean water!

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

Homeowner Manage ent Tasks
These operation and maintenance activities are your respo sibility. Use the chart on page 6 to track
your activities.
Identify the service intervals recommended by your ystem designer and your local government.
The tank assessment for your system will be the shorte t interval of these three intervals. Your
pumper/maintainer will determine if your tank needs to be pu ped.
System Designer: check every 24-36 months
My tank needs to be checked
Local Gover•nment: check every 36 months
State Requirement: check every 36 months eVely 36 mOrit11S
Seasonally or several times per year
. Leaks. Check(listen, look)for leaks in toilets and dri ping faucets. Repair leaks promptly.
• Su�facing sewage. Regularly check for wet or spon y 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 m e humans and animals sick.
. Alarms. Alarms signal when there is a problem; c ntact your maintainer any time the alann
signals.
. Lint,filter. If you have a lint filter, check for lint b ildup and clean when necessary. Consider
adding one after washing machine.
. Effluent screen. If you do not have one, consider aving one added the next tiine the tank is
cleaned.
Annually
. Water i�sage rate. A water meter can be used to mo itor your average daily water use. Compare
your water usage rate to the design flow of your sy em (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 an in place. Inspect for damaged caps at least
every fall. Fix or replace damaged caps before winte to help prevent freezing issues.
. Water conditioning devices. See Page 5 for a list of d vices. When possible,program the recharge
frequency based on water demand (gallons) rather t an time (days). Recharging too frequently
may negatively impact your septic system.
. Review your water usage rate. Review the Water se 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 Minnes ta.
. Make sure that your pumper/maintainer services the ank 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 Manage ent Tasks
These are the operation and maintenance activities that a umper/maintainer performs to help ensure
long-term performance of your system. Professionals sho dd refer to the O/M Manua!for detailed
checklists for tanks,pT�mps, alarms and other components. C Il 800-322-8642 for more details.
• Written record provided to hoineowner after each vis t.
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 he septic system.
. Review water usage rates (if available)with homeow er.
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.
• Liql�id level. Check to make sure the tank is not leak' g. The liquid level should be level with the
bottom of the outlet pipe. (If the water level is belo the bottom of the outlet pipe, the tank may
not be watertight. If the water level is higher than t e bottom of the outlet pipe of the tank, the
effluent screen may need cleaning, or there may be p nding in the drainfield.)
• Inspection pipes. Replace damaged caps.
. Baffles. Check to make sure they are in place and at ached, and that inlet/outlet baffles are clear
of buildup or obstructions.
• Effli�ent screerr. Check to make sure it is in place clean per manufacturer recommendation.
Recommend retrofitted installation if one is not prese t.
. Alarm. Verify that the alarm works.
• Scum and sludge. Measure scum and sludge in each ompartment of each septic and pump tank,
pump if needed.
Pump
• Pump and controls. Check to make sure the pump an controls are operating correctly.
. Pump vault. Check to make sure it is in place; clean r manufacturer recommendations.
• Alarm. Verify that the alarm works.
. Drainback. Check to make sure it is operating proper y.
. 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 co pare to the anticipated average daily flow
listed on Page 2.
Soil Treatment Area
• Inspection pipes. Check to make sure they are proper capped. Replace caps that are damaged.
• Sur/'acing of ef�luent. Check for surfaced effluent or ther signs of problems.
• Lateral flushing. Check lateral distribution; if cleano ts exist, flush and clean as needed.
. Ponding. Check for ponding. Excessive pondi g in at-grade and mound beds indicates
problems.

Orono, eE�nn p n.County
This on-site Sewage Treatment System is partially designed f r a Type l,five-bedroom home in
accordance with the Minnesota Pollution Control Agency Ch ter 7080 and local ordinances.
Once the house size,location and septic primary and future sit s are chosen this design can be completed.
The periodically saturated soils were located at 12-16 Inches( ottled soil).Due to the periodically
saturated soils,a pressurized mound system will need to be in lled to treat the septic effluent.T'he bottom
of the treatment area must be located at least 3'above the sa ated soils.
The soils at a depth of 12"have a percolarion rate averaging 8 PI.
The absorption areas do not overlap.
All tanks need to be insulated if there is less than two feet of c ver over the top of the tanks.A filter needs
to be installed on the second tank. Clean outs must be installed on the end of the laterals for maintenance.
A pumping chamber will need to be installed to lift the effluen to the treatment area. The power supply and
switches must be located outside the manhole and pumping ch mber in a weatherproof enclosure. A
warning device must be installed with a light and sound device this is in case of a pump failure.
Use 7/32 inch uerforations on the laterals.
Keep all heavy equipment off of the proposed treatment ar as before and after construction.The
treatment area must be fenced off before construction begi s.This Design is not valid&the System
will need to be relocated if failure to protect the areas prop sed for the On-Site Sewage Treatment
systems occurs.
Nothing other than gray water,(laundry,showers,ect.)human ater&toilet tissue should be disposed of
into the septic tanks_Garbage disposals are not recommended. dditives must not be used;they may cause
harmful damage to your septic system. It is recommended that ou pump the septic tank every year for 1
tank,every two years for two tanks.

This on-site Sewage Treatment System is designed for a Type 1 five-bedroom o e in accordance with the
Minnesota Pollution Control Agency Chapter 7080 and local o inances.
The periodically saturated soils were located at 12-16 inches(m ttled soil).Due to The periodically saturated
soils,a pressurized Mound System will need to be installed to septic eftluent.The bottom of the
treatment area must be located at least 3'above the saturated s ]s.
The soils at a depth of 12"have a percolation rate averaging S I.
All neighboring wells are located greater than 100'away from roposed treatment area.
All tanks need to be insulated if there is less than two feet of co er over the top of the tanks.Clean outs must
be installed on the end of the laterals for maintenance.
Use 7/32 in perforations in the laterals.
�R�NO COPY
A pwnping chamber will need to be installed to lift the effluent o the treatment area.The power supply and
Switches must be located outside the manhole and pumping ch ber in a weatherproof enclosure.A warning
device must be installed with light and sound devices;this is in e of a pump failure.The manifold and
supply line must have back drainage to the pumping chamber.
Kee all heav e ui ment off of the ro osed treatment ar s before durin and after construction.
The area around both sites must be fenced off b the contr tor before an construction be ins.This
Desi n is not valid and the S stem will need to be relocaied f failure to rotect the areas ro sed for
On-Site SewaQe Treatment occurs.
With proper installation and maintenance,this system should ve no probiem in treating septic ef�luent
effectively.Nothing other than gray water,(laundry,showers, c.)Human water and toilet tissue should be
disposed of into the septic tanks.Garbage disposals aze not rec mmended.Addirives must not be used;they
may cause harmful damage to your septic system.It is recomme ded that you pump the tanks every two years
Sincerely,
