MWRA is a public authority established by an act of the Legislature in 1984 to provide wholesale water and sewer services to 3.1 million people and more than 5,500 large industrial users in 63 communities in eastern and central Massachusetts.

Since its creation in 1985, MWRA has invested more than $6 billion in essential new facilities. In addition to the clean-up of Boston Harbor and the modernization of the region’s water system, MWRA maintains hundreds of miles of water and sewer pipes, and dozens of other facilities that regularly require either upgrades or replacements. MWRA has also established aggressive maintenance programs to ensure that these facilities never fall back into a cycle of disrepair.
