Water supply in a building is a fundamental aspect of its design and maintenance. It involves the provision of clean and adequate water for various uses, such as drinking, cooking, bathing, and cleaning. Ensuring an efficient and reliable water supply system is crucial for the comfort and health of the occupants. The water supply system in a building consists of several components, including the source of water, the distribution network, and the storage system.
