What is a Sanitary Sewer Overflow (SSO)? 

A Sanitary Sewer Overflow (SSO) is an unintentional discharge of wastewater to the environment prior to reaching a treatment facility. SSOs occur on infrequent occasions when the capacity of the sewer system is exceeded, usually due to extreme conditions such as heavy rainfall, or an obstruction or break in sewer systems (mains or pump stations).

314 CMR 16: Notification Requirements to Promote Public Awareness of Sewage Pollution

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 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:Notification Requirements to Promote Public Awareness of Sewage Pollution).

In the event of a SSO, the Town of Milton shall issue a public advisory notification according to the 314 CRM 16 requirements when applicable.
