For human consumption water is collected from different locations; i.e. groundwater, surface water from rivers and lakes, and from water reservoirs. In some parts of the world, even seawater can be used after a thorough desalination process.
Before use water must always be purified,regardless of the source.Water from certain areas may only need filtration and aeration, while water from other locations may need to go through a disinfection process before it is ready for use. Water treatment typically takes place in a water plant, in which the valves are often equipped with either electrical or pneumatic actuators to enable remote operation and control.
