SSO Notifications

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 certain Sanitary Sewer Overflows (SSOs).  The Massachusetts Department of Environmental Protection (MassDEP) and the Town of Ayer recognizes the importance of notifying the public when untreated sewage is released into our waters. 

When a discharge or overflow occurs, Ayer DPW sends out a public advisory notification.  On business days, this website will be updated within 4 hours of the notification. During nights, 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 Ayer DPW Sewer Division in the Permitted field and click “Search.”
