What role do surge tanks play in water systems?

Surge tanks primarily serve to maintain consistent pressure within a water system. They act as buffers that accommodate fluctuations in water flow and pressure caused by changes in demand or operational conditions, such as pump starts and stops. By maintaining a stable pressure, surge tanks help to prevent issues like water hammer, which can damage pipes and equipment. They also provide a reserve of water that can be quickly accessed in case of sudden demand spikes, thus contributing to the overall reliability and efficiency of the water supply system.

While storing excess water, filtering sediment, and regulating temperature are important functions in various water system components, these roles are not the primary purpose of surge tanks. Instead, their main focus is on pressure management to ensure a steady and reliable flow of water throughout the system.
