Sanitary Sewerage Overflow (S.S.O) Notification

The Town of Northfield Wastewater Division works diligently to ensure that the Town’s sewage is conveyed through the sewer system to the wastewater treatment plant. Spills or overflows of sewage into a water body are rare. If for any reason this occurs, the Town has implemented a Sanitary Sewer Overflow (SSO) alert system in accordance with MassDEP regulations 314 CMR 16.00 to notify you where and when the sewage overflow occurred. This is so all citizens can be aware of the situation and take any necessary precautions.

When a discharge or overflow occurs, the Town sends out a public advisory notification. On business days, this website will be updated within 48 hours of the notification. During weekends or holidays, this website will be updated on the next business day. 

You can also see a list of discharge and overflow events on the MassDEP website:

This list is updated within 24 hours of when the public advisory notification is sent. Enter the Treatment Plant Permittee Name in the Permittee field and click “Search”. For the Town of Northfield, the Permittee name is the name of the Chief Operator.
