In the 1880s, the calf pasture on Columbia Point was used as a Boston sewer line and pumping station. This large pumping station still stands and in its time was a model for treating sewage and helping to promote cleaner and healthier urban living conditions. It pumped waste to a remote treatment facility on Moon Island in Boston Harbor, and served as a model for other systems worldwide. This system remained in active use and was the Boston Sewer system's headworks, handling all of the city's sewage, until 1968 when a new treatment facility was built on Deer Island. The pumping station is also architecturally significant as a Richardsonian Romanesque designed by the then Boston city architect, George Clough. It is also the only remaining 19th century building on Columbia Point and is in the National Register of Historic Places.
