A water supply network is a system of engineered
hydrologic and
hydraulic components, including: the
watershed or geographic area that collects the water, see water purification - sources of drinking water; a raw (untreated) water reservoir (above or below ground) where the water gathers, such as a
lake, a
river, or
groundwater from an underground
aquifer; a means for delivery from the source to a point of treatment, such as (underground)
piping, uncovered ground level
aqueducts and/or
tunnels;
water purification, such as a water treatment plant; transmission from treatment, through
pipes to treated water storage, that may be either elevated or ground level; and distribution through
piping/
watermains from storage to consumption (at houses,
fire hydrants, industrial use points, etc).
