Ende Septic Service Designer Signature Company C9206 License # UNIVERSITY OF MINNESOTA 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.

Chart on page 6 can help track your activities. Your toilet is not a garbage can. Do not flush anything besides human waste and toilet paper. No wet wipes, cigarette butts, disposal diapers, used medicine, feminine products or other trash! The system and septic tanks needs to be checked every 38 months Your service provider or pumper/maintainer should evaluate if your tank needs to be pumped more or less often. Seasonally or several times per year • Leaks. Check (listen, look) for leaks in toilets and dripping faucets. Repair leaks promptly. • Soil treatment area. 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 and leaks, call your service professional. Untreated sewage may make humans and animals sick. Keep bikes, snowmobiles and other traffic off and control borrowing animals. Alarms. Alarms signal when there is a problem; contact your service professional any time the alarm signals. Lint filter. If you have a lint filter, check for lint buildup and clean when necessary. If you do not have one, 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 along with an alarm. Annually Water usage rate. A water meter or another device 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 ifyour 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 water demand (gallons) rather than time (days). Recharging too frequently may negatively impact your septic system. Consider updating to demand operation if your system currently uses time, • Review your water usage rate. Review the Water Use Appliance chart on Page 5. Discuss any major changes with your service provider or pumper/maintainer. During each visit by a service provider or pumper/maintainer Make sure that your service professional services the tank through the manhole. (NOT though a 4" or 6" diameter inspection port.) Ask how full your tank was with sludge and scum to determine if your service interval is appropriate. Ask your pumper/maintainer to accomplish the tasks listed on the Professional Tasks on Page 4. -3- Septic System Management Plan UNIVERSITY for Above Grade Systems OF MINNESOTA Professional Management Tasks it These are the operation and maintenance activities that a pumper/maintainerperforms to help ensure long- term performance of your system. At each visit a written report/record must be provided to homeowner. 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 soil treatment area.) Inspection pipes. Replace damaged or missing pipes and 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 draining properly. • Event counter or elapsed time meter. Check to see if there is an event counter or elapsed time meter for the pump. If there is one or both, calculate the water usage rate and compare to the anticipated use listed on Design and Page 2. Dose Volume: 150 gallons: Pump run time: 4.3 Minutes Soil Treatment Area • Inspection pipes. Check to make sure they are properly capped. Replace caps and pipes that are damaged. • Surfacing of effluent. Check for surfacing effluent or other signs of problems. • Lateral flushing. Check lateral distribution; if cleanouts exist, flush and clean at recommended frequency. • Vegetation - Check to see that a good growth of vegetation is covering the system.
