What does a surge tank help control in a water system?

A surge tank is specifically designed to help control pressure fluctuations in a water system, particularly during sudden changes in flow, such as valve closures or pump start-ups. When these abrupt changes occur, they can create pressure surges, commonly known as water hammer, which can damage pipes and equipment.

By absorbing excess pressure, a surge tank acts as a buffer, allowing the system to stabilize and preventing damaging shocks. While it may indirectly influence other factors such as water levels or flow rates, its primary function is to mitigate the effects of pressure changes. This makes it an essential component for maintaining the integrity and efficiency of the water distribution system.
