WILMINGTON, MA — In January 2021, Governor Baker signed An Act Promoting Awareness of Sewage in Public Waters into law. This new law will make sure the public knows when untreated sewage flows into Massachusetts waters. This includes releases known as combined sewer overflows (CSOs) and certain Sanitary Sewer Overflows (SSOs).
MassDEP recognizes the importance of notifying the public when untreated sewage is released into our waters and has developed regulations to implement this law (314 CMR 16.00: Notification Requirements to Promote Public Awareness of Sewage Pollution).
When a discharge or overflow occurs, the Town of Wilmington Sewer Department or Board of Health sends out a public advisory notification. On business days, this website will be updated within 8 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.
