About Sewer Maintenance

Will & Tom vactor

Public Works maintains 115 miles of separated sanitary sewer mains, which transport water carrying human and domestic wastes to the Massachusetts Water Resources Authority (MWRA) collection system for processing at the wastewater treatment facility at Deer Island.  Public Works also maintains 78 miles of separated stormwater mains and 43 miles of combined sewer mains.

An important component of the Sewer Division’s work is to meet with residents, business owners, and citizen groups to advise them of the best known methods to avoid sewer backups and to define the responsibility of the city and the homeowner regarding sewer connections.

This division also assists with the development and management of critical projects such as the city's stormwater plan, inflow and infiltration studies, combined sewer overflow monitoring, stormwater quality sampling, and the administration of the Fats, Oils, and Grease program (FOG). Sewer Division engineers also oversee the design and construction of sewer separation projects
