Quick Summary

A surge chamber, also known as a surge tank, is an engineering component used in closed aqueduct or feeder pipe systems. Its primary function is to manage sudden changes in water pressure.1

Specifically, a surge chamber acts as a standpipe or storage reservoir. It absorbs sudden increases in pressure, preventing damage to the system. Conversely, it also supplies water quickly during a drop in pressure, ensuring a consistent flow. This helps to stabilize the system and maintain efficient operation.12
