. The scheme was a success, with additional pumping stations being added in 1899 and 1909, to cope with the demand for power. Modernisation started in the 1920s, when the original steam pumps were replaced by electric motors at two of the pumping stations. The greatest volume of water was supplied in the 1920s, although the length of the water mains continued to increase until 1948. Usage started to decrease in the 1930s, and the first pumping station was closed in 1939. By the 1960s, there were serious concerns about the state of some of the equipment and corrosion in the high-pressure mains, and in 1968 the Corporation announced their intent to switch the system off, which they did at the end of 1972.

 in 1891, which would authorise them to build a network to distribute hydraulic power to the city.

The Corporation had the advantage over a private company that they did not have to apply for permission to dig up the streets in order to install the network of high-pressure water mains. The pumping station was situated on Whitworth Street West, between Oxford Road railway station and the Rochdale Canal

. The working pressure was set at 1120 pound per square inches (77.2 bar), much higher than the 700 pound per square inches (48.3 bar) of the London system, because it was expected that much of the power would be used for baling cotton, and the extra pressure was dictated by the design of existing baling equipment. The pressure was supplied by six triple-expansion steam engines, rated at 200 hp each, and was maintained by two hydraulic accumulator

s, with pistons of 18 inches (457.2 mm) diameter, a stroke of 23 feet (7 m), and loaded with 127 tonnes. The equipment was supplied by Ellington's company. The installation was completed by 1894, and by 1895 there were 12 miles (19 km) of hydraulic pipes under the city streets, providing power for 247 machines.

Demand for the utility was high, and a second pumping station commenced operation on 6 July 1899. This was constructed at Pott Street in Ancoats

, close to the Rochdale Canal, and initially had four pumping engines and two accumulators. The number of engines was eventually increased to seven, six of 210 hp and one of 350 hp. A third pumping station was soon required, which was constructed between Water Street and the River Irwell

. Again, it had two accumulators, and six steam engines. Coal for the engines was delivered by boat, and it began operating on 14 October 1909. Although all three pumping stations were situated beside waterways, the water supply for the system was obtained from boreholes. That at Whitworth Street was 613 feet (186.8 m) deep, and the water at all three was raised by compressed air delivery systems, which lasted until 1948, when they were superseded by submersible pumps. By the 1930s, the system had grown to 35 miles (56 km) of pipes working some 2400 machines.

Replacement of the steam engines began in 1922, at Whitworth Street. Four of the pumping engines were removed altogether, to be replaced by electrically driven centrifugal pump

s. This work was completed by 1924. The following year, the remaining two were treated differently, as the pumps were retained, but the steam cylinders were removed, and the flywheels were replaced by a helical gear drive, to connect the pumps to 220 hp electric motors. These were variable speed direct current devices, and a motor converter set had to be installed, to provide the low voltage DC supply from the incoming high voltage alternating current supply. The motor converter set had been built in 1914, and was obtained second-hand. The pumps at the Water Street station were converted to electrical operation in a similar manner soon afterwards.

Decline

The demand for hydraulic power began to fall in the 1930s, as electric power

 became more popular, but although the number of customers dropped, the supply pipes continued to be extended until they reached their maximum length of 35.5 miles (57.1 km) in 1948. The Pott Street pumping station was closed in 1939. By the 1960s, the motor converter set was 50 years old, and most of the pumps were older still. The effects of corrosion on high-pressure water mains were also a cause for concern. In 1964, a similar system in Glasgow, opened a year later than the Manchester system and also using water at 1120 psi (77.2 bar) was switched off and some of the equipment was used to refit Whitworth Street station. The two centrifugal pumps and one of the converted steam pumps were removed, to be replaced by two high-speed reciprocating pumps obtained from Glasgow. Although not ideal for a diminishing network, because they were fixed speed devices, they provided a back-up system if there were problems at Water Street.

By 1968, the length of pressure main had been reduced to 26 miles (41.8 km), and the Waterworks Committee gave notice to all 120 customers that the system would be shut down in four years' time. By that time, the stations were supplying 2 million gallons (9.1 Megalitres) of pressurised water per year, down from the 360 million gallons (1,600 Ml) which were supplied when the system was at its peak. The system was formally switched off on 28 December 1972, when the Chairman of the Waterworks Committee stopped the pumps at a ceremony.

Pumping stations

The three hydraulic power stations were located at Whitworth Street West

The Whitworth Street station was opened in 1894. It was located on the banks of the Rochdale Canal

, between the canal and Oxford Road railway station. It was the first to be upgraded to electrical operation, but was little used after 1964, as it held equipment bought from Glasgow, which was only used as a backup. Following the closure of the system, its contents were sold for scrap and the building was demolished.

Pott Street station was located in Ancoats and opened in 1899. It was not electrified, and was shut down in 1939. Both its site and Pott Street have now disappeared, as they now form part of the car park at the Central Retail Park in Ancoats.

The third station was at Water Street, on the banks of the River Irwell
