A water supply system typically includes: - A drainage basin (see water purification - sources of drinking water). - A raw water collection point (above or below ground) where the water accumulates, such as a lake, a river, or groundwater from an underground aquifer. Raw water may be transferred using uncovered ground-level aqueducts, covered tunnels or underground water pipes to water purification facilities. - Water purification facilities. Treated water is transferred using water pipes (usually underground). - Water storage facilities such as reservoirs, water tanks, or water towers. Smaller water systems may store the water in cisterns or pressure vessels. Tall buildings may also need to store water locally in pressure vessels in order for the water to reach the upper floors. - Additional water pressurizing components such as pumping ...
