How often should I pump my septic system?
On average, around every 3-5 years. However, the real timeframe varies and depends on your water use, the size of the tank, the number of people in the house, and types of appliances in use such as garbage disposals or washing machines.

The Cooperative Extension booklet "Protecting Your Water and Septic System" has a helpful risk assessment and chart of more specific recommended pumping times.Protecting Your Water and Septic System Booklet
