Early types of pumps ranged from piston or plunger pumps to centrifugal pumps. Although some screw pumps were used, they generally did not meet with widespread success. Centrifugal pumps required a rather constant volume of sewage, thus requiring a storage basin at the pumps' suction. Piston pumps usually required the sewage to be screened prior to pumping to reduce the probability of damage to the pump. Overall, centrifugal pumps began to be favored. See Tracking Down the Roots of Our Sanitary Sewers, Parts 1-5, for more information. |

Details of Isaac Shone's Pneumatic Sewerage System, used in London circa 1884. This system was successfully used in London. It is a "separate" system, with sewage and rainwater disposed of by separated systems. Gravity delivers sewage to district collectors, then pneumatic ejectors raise sewage and deliver it to disposal points. See pp. 30-33 of source article for detailed information. Samuel M. Gray, Proposed Plan for a Sewerage System, and for the Disposal of the Sewage of the City of Providence (Providence: Providence Press Company, Printers to the City, 1884), Plate 12, opposite page 32. |

Sewerage pumping plant in Milwaukee, Wisconsin, 1893, showing the pump well, pump, engine, and discharge into the lake. Sewage and factory wastes were discharged into Milwaukee's streams and rivers in the 1870s, leading to disease and environmental degradation. This pumping plant was part of the plan implemented in the 1880s to correct the problem. The original designers (1880) were E. S. Chesbrough, Moses Lane and George E. Waring, Jr. The plan was expanded in the 1880s by the author, G. H. Benzenberg. Source: G. H.
