Providence Sewage Treatment System, Fields Point Plant, Return Sludge Pumping Station, Ernest Street, Providence, Providence County, RI

Significance: Built in 1934-35, this building is directly associated with the conversion of Providence's Fields Point Sewage Treatment Plant from the chemical precipitation process to the activated sludge process. It contained the pumps which returned a portion of biologically active sludge back into the treatment process, and as such was integral to the modernized operations of the plant.
