What is the significance of pressure testing in water distribution systems?

Pressure testing in water distribution systems is critical for verifying the integrity of the system before it is put into service. This process involves applying a specified pressure to the system to ensure that it can withstand operational pressures without leaking or failing. The main objectives of pressure testing include detecting leaks, which could lead to significant water loss or contamination of the water supply, and ensuring the overall safety of the system.

When a system passes a pressure test, it indicates that the materials and joints are secure and that the distribution lines will function properly under normal operating conditions. If leaks are detected, they can be addressed before the system is put into service, which helps to prevent future issues that could lead to costly repairs, loss of water, or health hazards.

Other options, such as calculating water flow rates, measuring water temperature, or assessing the chemical composition of water, do not directly relate to the purpose of pressure testing. While these processes are essential in managing water distribution systems, they do not address the structural integrity and safety concerns that pressure testing specifically targets.
