What is the primary function of a surge tank?

• A. To store water for long durations
• B. To prevent contamination from rodents
• C. To absorb sudden changes in water pressure
• D. To elevate water above ground level

Answer: (C)

The primary function of a surge tank is to absorb sudden changes in water pressure. Surge tanks are crucial in water distribution systems and are specifically designed to mitigate the effects of pressure surges or "water hammer" that can occur during rapid changes in water flow, such as when pumps are turned on or off. By providing a buffer, surge tanks help stabilize the system, reduce the risk of pipe bursts, and protect other equipment from damage due to sudden pressure fluctuations. In a well-designed water system, managing pressure variations is essential for maintaining operational efficiency and prolonging the lifespan of pipes and valves. Thus, the surge tank serves a vital role in ensuring the stability and safety of the water supply system.
