The reliability of a rainwater harvesting system is a measure of its ability to produce the water needed by the system users and depends partially upon the rainfall distribution of the area, the size of the collection roof, the capacity of the storage tank, and the daily demand for the water. What is a domestic pressure tank?What is a domestic pressure tank?Domestic Water Supply with a Pressurized Tank. Domestic water supply system with pressurized tank The pressurized tank is partly filled with air (or gas) behind a membrane. The air compensates for pressure variations during consumption and when supply pump starts and stops. A pressurized tank has a limited compensating capacity for the shortage in a main supply line.Design of Domestic Service Water Supply Systems
