In a closed, automatic water system a pressure tank is used to store water and maintain system pressure between specified limits (such as 30 to 50 PSI). As the water level in the tank rises, tank air is compressed in the upper part of the tank until the upper pressure limit is reached (i.e., 50 PSI).Selecting and Sizing Water-Storage TanksSelecting and Sizing Water-Storage Tanks namibia cave tank domestic water supply system volume Peak demand is usually the first factor to consider when sizing a distribution system tank.

An elevated steel reservoir stores clean water in a steel tank on a raised stand or tower. The elevation of the tank provides the water pressure to all points in the pressure zone of the distribution system. Tanks may be cylindrical, rectangular or any other convenient shape. For family use, the tank can be made of an old oil drum (duly coated), and theWater Tanks & System Distribution - United States ArmyThe minimum pipe diameter in the distribution system shall be 100mm (4 inch). The maximum velocity shall be 5 feet per second (1.5 meters per second) at 150% of the fixture unit flow or times the average daily flow2 (8-hour basis), whichever is greater.Water Supply Systems and Evaluation Methods: Volume IMaximum day demand: At the maximum day demand, the required pumping rate is 6 mgd with no water taken from storage. The pumping head required is equal to the hydraulic gradient at the tank, plus the head loss in 35,000 feet of equivalent pipe at 6.0 mgd or 130 + (1.42 × 35) = 195 feet.
