The waterworks should be located near the water source to reduce the laying distance of the pipe network, generally located in the upstream direction of the river. There will be polluting factories in urban areas, causing water pollution.
The water plant should filter and disinfect the water in the reservoir to meet the national standards. The water supply station supplies the treated water from the water plant to all water-using places, including drinking water. The water supply station does not purify water, and the water from the water plant is supplied to others. Waterworks produce domestic water for various users such as factories, mines and residents.
