The Deer Island Waste Water Treatment Plant (also known as Deer Island Sewage Treatment Plant) is located on Deer Island, one of the Boston Harbor Islands in Boston Harbor. The plant is operated by the Massachusetts Water Resources Authority (MWRA) and began partial operations in 1995. The facility was fully operational in 2000 with the completion of the outfall tunnel.[1]

Deer Island is the second largest sewage treatment plant in the United States.[2] The plant is a key part of the program to protect Boston Harbor from pollution from sewer systems in eastern Massachusetts, mandated by a 1984 federal court ruling by Judge Paul G. Garrity, in a case brought under the Clean Water Act.[3][4] These lawsuits culminated in Federal District Judge A. David Mazzone’s 1985 ruling that made the cleanup of the Boston Harbor a non-voluntary, court-ordered mandate.[5]

From the 1880s until 1991, the northeastern side of the island was the location of the Deer Island Prison.
