	Water supply network - Wikipedia, the free encyclopedia
		Water purification usually occurs close to the final delivery points to reduce the chances of the water becoming contaminated after treatment.
		That energy is transferred to the water, therefore becoming water pressure, in a number of ways: by a pump, by gravity feed from a water source (such as a reservoir or a water tower) at a higher elevation, or, in smaller systems, by compressed air.
		Water supply networks are part of the master planning of communities, counties, and municipalities.

	Water Technology - Crystal Project, Douglas Water Treatment Plant (WTP)
		When the Isle of Man Water Authority was formed back in 1972, it inherited a complex system of mains, service reservoirs and pumping stations, many of which had been run independently by the small regional water boards previously responsible for the island’s supply.
		A number of the reservoirs and pumping stations had been first commissioned in the 1940s and 1950s and some of the mains were installed in the mid-nineteenth century.
		A strategic plan for the replacement and refurbishment of the infrastructure was formally adopted by the Tynwald in June 1999; originally using the year 2016 as the target and a projected population of 81,000.
