In 1984, legislation was enacted to create the Massachusetts Water Resources Authority (MWRA). The MWRA is a public authority that provides wholesale water and sewer services to 3.1 million people and more than 5,500 large industrial users in 61 communities in eastern and central Massachusetts. The primary mission of the MWRA was to clean up Boston Harbor and modernize the area’s water and sewer systems. Other key elements have included a major capital program to repair and upgrade the systems, increase staff to improve operations and maintenance, promote water conservation and plan for the future to meet growing demand.
Boston’s water system has been governed by various water authorities over the years starting with the Cochituate Water Board (1845-1875), followed by the Boston Water Board (1875-1895), Metropolitan Water Supply Commission (1926-1946), Metropolitan District Commission (1946-1985) and finally the MWRA (1985-present).
