This diagram shows a water supply system for a hotel. The system consists of a cistern, a pump, a pressure gauge, a tank, a cooler, and filters. The cistern is a large tank that stores water from a well or other source. The pump pumps the water from the cistern to the tank. The pressure gauge measures the pressure of the water in the tank. The tank stores the water at a constant pressure. The cooler cools the water before it is distributed to the hotel's rooms and other facilities. The filters remove impurities from the water.
