Sewer Overflows

When a sanitary sewer discharge or overflow (SSO) occurs, the Town of Plymouth sends out a public advisory notification. During regular business hours, this website will be updated as soon as possible. In the event discharges occur outside of regular business hours, on weekends, or holidays, this website will be updated during the next business day.

You can also see a list of SSO events on the MassDEP website. This list is updated within 24 hours of when the public advisory notification is sent. Enter 'Plymouth' in the Municipality field and click "Search".
