The original Abbey Mills Pumping Station, in Mill Meads, East London, is a sewage pumping station, designed by engineer Joseph Bazalgette, Edmund Cooper, and architect Charles Driver. It was built between 1865 and 1868, housing eight beam engines by Rothwell & Co. of Bolton. Two engines on each arm of a cruciform plan, with an elaborate Byzantine style, described as The Cathedral of Sewage. Another of Bazalgette's designs, Crossness Pumping Station, is located south of the River Thames at Crossness, at the end of the Southern Outfall Sewer.
