The Deer Island Wastewater Treatment Plant, located in Boston Harbor and operated by the MWRA, is one of the largest and most advanced facilities in the U.S., serving over 2 million people in 43 communities. It treats up to 1.2 billion gallons of wastewater per day—removing more than 85% of pollutants—before safely releasing cleansed water into Massachusetts Bay via a 9.5-mile outfall tunnel. The plant also generates energy from methane produced during sludge digestion, supporting on-site power needs.

Jeanine and I completed the 2.6-mile walk around the perimeter of this island in very high winds. We did so in the early morning after dropping Marie and Rose at the airport for their return to Minnesota. In addition to being a state-of-the-art facility, it is actually quite beautiful from an architectural perspective.
