Two major systems were built in Australia. The first was in Melbourne, where the Melbourne Hydraulic Power Company began operating in July 1889. The company was authorised by an Act of the Victorian Parliament passed in December 1887, and construction of the system began, with Coates & Co. acting as consulting engineers, and George Swinburne working as engineering manager. The steam pumping plant was supplied by Abbot & Co. from England. Expansion was rapid, with around 70 machines, mainly hydraulic lifts, connected to the system by the end of 1889, and a third steam engine had to be installed in mid-1890, which more than doubled the capacity of the system. A fourth pumping engine was added in 1891, by which time there were 100 customers connected to the mains. The mains were a mixture of and pipes. The water was extracted from the Yarra River until 1893, after which it was drawn from the Public Works Department's supply. There were some of mains by 1897. A second pumping station was added in 1901, and in 1902, 102 million gallons (454 megalitres) of pressurised water were used by customers.
