All water supply systems use a coination of pipes (of different dimensions and materials), valves and outlets to deliver water to building users. Some water supply systems also use storage pipess and pumps. Designing a water supply system involves getting all of these elements right so that clean water is delivered to the user at the appropriate rate and temperature.
