Your septic system is designed to kill harmful organisms and rcmove pollutants before the water is recycled back inlo our lakes, streams and groundwater. This management plan will identiry the operation and maintenance activilies necessary to ensure long- lerm 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 pmvider- However, it is YOUR rcsponsibility to make sure all tasks get accomplished in a timely manner.

Consider adding one after washing machine. a EflIuent screen. lf you do not have one, consider having one added the next time the tank is cleaned. Annuelly o Vater usage rale. 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 lhe next page). Contact your septic professional if your average daily flow over the course of a month exceeds 70olo of the design flow for your system. o Caps.Make sure that all caps and lids are intact and in place. Inspect for damaged caps at least every fall. Fix or rcplace damaged caps before winter to help prcvent freezing issues. o lYater conditioning devices- See Page 5 for a list of devices.
