Deer Island Wastewater Treatment Plant

The Deer Island Wastewater Treatment Plant, situated on the Boston Harbor, receives and treats wastewater from 43 greater Boston communities, which together comprise over 5,000 miles of sewer pipe. It is the second-largest wastewater treatment plant in the United States, and treats an average 300 million gallons of wastewater per day. At Deer Island, wastewater goes through primary and secondary treatment before its eventual discharge 9.5 miles offshore into Massachusetts Bay. In addition to treating wastewater, Deer Island processes sludge, a byproduct of treatment, into a pellet fertilizer for use in agriculture and landscaping.
