Massachusetts Water Resources Authority is a public authority established by the Massachusetts General Court in 1985 to provide wholesale water and sewer services. It was created in response to a federal court order to clean up Boston Harbor, which had become severely polluted due to inadequate regional wastewater treatment. The authority assumed control of key infrastructure from the Metropolitan District Commission and has since been responsible for one of the largest public works programs in New England history. Its mission focuses on delivering safe drinking water, treating wastewater to high environmental standards, and managing combined sewer overflows to protect regional water bodies.

History and formation

The formation was directly precipitated by a landmark 1983 lawsuit, United States v. Metropolitan District Commission, filed by the Conservation Law Foundation and the U.S. Environmental Protection Agency under the Clean Water Act. The suit targeted the gross pollution of Boston Harbor from the antiquated Deer Island Sewage Treatment Plant and other facilities operated by the Metropolitan District Commission. In 1985, facing a federal court mandate, the Massachusetts Legislature passed the Massachusetts Water Resources Authority Act, dissolving the old agency's water and sewer divisions. The new authority was tasked with financing and executing a multi-billion dollar court-ordered cleanup, famously overseen by federal judge A. David Mazzone. This period coincided with the administration of Governor Michael Dukakis and set the stage for decades of massive infrastructure investment.

Infrastructure and operations

The system's core drinking water supply originates from the Quabbin Reservoir and the Wachusett Reservoir, which are managed by the Massachusetts Department of Conservation and Recreation. It operates the John J. Carroll Water Treatment Plant in Marlborough and maintains over 5,000 miles of water mains and sewers. For wastewater, its primary facility is the massive Deer Island Sewage Treatment Plant, which underwent a complete reconstruction and now uses advanced primary and secondary treatment processes. The authority also manages the Nut Island headworks and a network of interceptor sewers, pumping stations, and the 9.5-mile-long Deer Island Outfall Tunnel that discharges treated effluent into Massachusetts Bay. Key operations include the Metropolitan Tunnel System and the Chestnut Hill Pumping Station.

Service area and governance

It provides wholesale water and sewer services to 3.1 million people and over 5,500 large industrial users in 61 communities across eastern Massachusetts, including the city of Boston and much of the surrounding Greater Boston metropolitan area. Member communities range from Cambridge and Somerville to the North Shore and South Shore regions. Governance is provided by an 11-member board of directors, with members appointed by the Governor of Massachusetts and mayors of key cities like Boston and Cambridge. The board oversees the executive director and sets policies, budgets, and rates, ensuring coordination with state agencies like the Massachusetts Department of Environmental Protection.

Water quality and environmental initiatives

The authority is renowned for transforming Boston Harbor from one of the nation's most polluted to a swimmable and fishable water body, a achievement recognized by the U.S. Environmental Protection Agency. It conducts extensive monitoring for contaminants like lead, copper, and PFAS, consistently meeting all federal Safe Drinking Water Act standards. Major environmental projects include the $3.8 billion Boston Harbor Project, the construction of the Deer Island Outfall Tunnel, and ongoing programs to reduce combined sewer overflow events into the Charles River, Mystic River, and Neponset River. It also engages in habitat restoration, including work on the Fore River Sanctuary, and promotes water conservation through public outreach.

Financial structure and rates

As an independent public authority, it finances its operations and massive capital projects primarily through the sale of bonds and the collection of user charges from its member communities, not through state taxes. Its bond issuances are rated by agencies like Moody's Investors Service and Standard & Poor's. Rates for water and sewer services are set annually by its board to cover debt service on bonds sold for projects like the Boston Harbor Project, as well as operations and maintenance costs. These rates are then passed on to residents and businesses by local municipalities. The authority's financial practices are scrutinized by the Massachusetts Water Resources Authority Advisory Board and must comply with regulations from the Massachusetts Department of Public Utilities.

Major projects and challenges

The single largest undertaking was the court-mandated Boston Harbor Project, one of the most expensive public works projects in U.S. history, which included the complete redesign and construction of the Deer Island Sewage Treatment Plant. Current major capital projects include the ongoing rehabilitation and replacement of aging water mains and sewers, some dating to the 19th century, and the implementation of green infrastructure to manage stormwater. Persistent challenges include addressing the impacts of climate change, such as sea-level rise on coastal facilities like those on Deer Island, mitigating combined sewer overflows during heavy rainfall, and managing the costs of infrastructure maintenance amid rising construction expenses. The authority also coordinates with the Massachusetts Emergency Management Agency on security and disaster preparedness.
