In January 1891, a system in Sydney came on-line, having been authorised by act of Parliament in 1888. George Swinburne was again the engineer, and the system was supplying power to around 200 machines by 1894, which included 149 lifts and 20 dock cranes. The operating company was the Sydney and Suburbs Hydraulic Power Company, later shortened to the Sydney Hydraulic Power Company. Pressure mains were either of or diameter, and at its peak, there were around of mains, covering an area between Pyrmont, Woolloomooloo and Broadway. In 1919, most of the 2369 lifts in the metropolitan area were hydraulically operated. The pumping station, together with two accumulators, was situated in the Darling Harbour district, and the original steam engines were replaced by three electric motors driving centrifugal pumps in 1952. The scheme remained in private ownership until its demise in 1975, and the pumping station has since been re-used as a tavern.
