During heavy rainfall, these systems are prone to being overloaded and designed to release excess flows into local bodies of water. To better manage overflows and protect water quality - particularly as rainfall events become more frequent and intense - the Massachusetts Water Resources Authority is implementing a Combined Sewer Overflow (CSO) Control Program which involves modernizing infrastructure with the latest technology. East Boston is among communities at the center of this effort. Stantec, a design and engineering company, was selected to lead design services on Phase IV of the Boston Water and Sewer Commission’s (BWSC) East Boston Sewer Separation project. The project is part of the comprehensive 30-year initiative to reduce pollutants discharged to Boston Harbor and its tributary waters while upgrading water infrastructure in the rapidly developing neighborhood. The work will enhance water, sewer, and storm drainage systems to support ongoing growth and prosperity of the community. Phase IV involves separating approximately 230 acres of combined sewer area, along with installing new storm drains, updating existing sewers, replacing adjacent aging water mains, and modifying existing regulator structures. For more than three decades, Stantec has partnered with the BWSC, collaborating to complete some of Boston’s most complex and demanding sewer separation and infrastructure improvement projects. Most recently, the team finished work on Phase III of the East Boston Sewer Separation project in accordance with a fast-track schedule. Using the Commission’s hydrologic/hydraulic model, Stantec prepared plans for installing 9000 feet of new water main, 4000 feet of sewer, and 7300 feet of storm drain. The project also involved rehabilitating 2300 feet of existing wastewater piping and modifying three regulator manholes to improve hydraulic performance and reduce overflows. “Water infrastructure plays a crucial role in a city like Boston, where factors such as climate change, population growth, and new development only further stress existing resources,” said Mike Carroll, Stantec project manager. “We’re proud to continue a decades-long relationship with the BWSC to improve the historic and essential waterways while helping modernize this infrastructure across several neighborhoods to support residents and businesses into the future.” WTR
