The City of Cambridge experienced a sanitary sewer overflow that began on Monday, January 26 and ended on Tuesday, January 27. The overflow was caused by an accumulation of fat and grease in the sewer system near the intersection of Water Street and High Street, resulting in untreated sewage leaking from manholes on Water Street.
System Improvements Underway
City officials are prioritizing upgrades to our sanitary sewer system. In 2024, we replaced sewer lines in the West End, which has reduced the frequency and intensity of overflows on Water Street. We are also preparing to begin renovation work on the Trenton Street Sewage Pumping Station, originally built in 1938, which currently conveys between 1.5 and 2 million gallons of sewage daily. Additionally, we plan to submit a grant application to re-line the Cambridge Creek Interceptor, the sewage collection pipes that convey sewage around Cambridge Creek.
Help Prevent Future Overflows
Residents can help prevent sewer overflows by never pouring bacon fat or other greases down sink drains. These substances harden in the sewage collection system and can cause blockages leading to overflows. Instead, line a bowl with foil, pour the grease into the foil, and allow it to harden before disposing of it in the trash.
