Old and New

View of the Old Pumping Station (built 1898, expanded in 1909), with the iconic egg-shaped digesters in the distance (built 1990s). The plant processes wastewater from 2.5 million people in the greater Boston area. Since it came online in the mid-1990s, the quality of Boston Harbor has improved greatly. SNEC-SIA tour of Deer Island Wastewater Treatment Plant, Boston, Massachusetts, June 27, 2014.

1909 Triple Cylinder Steam Pump

Pump No. 4, built as part of the 1909 pumping station expansion. The Reynolds-Corliss engine features three cylinders, set at 120 degrees to each other. The design allowed steam to pass from the first cylinder to the second, and finally on to the third. As the steam passed to successively larger cylinders, it expanded, thereby providing additional energy at each step before being expelled from the engine. The engine drove a centrifugal pump rated at 100 million gallons per day. The Old Pump Station and en…
