These three components—water treatment plants, reservoirs, and dam structures—are interconnected in the water supply and management system. The water treatment plant processes raw water from the reservoir or other sources to provide clean and safe drinking water to communities. The reservoir, in turn, stores water, which may come from rainfall, rivers, or other sources, and the dam structure helps regulate the flow and release of water from the reservoir, supporting various human needs while mitigating floods and managing water resources efficiently.
