Detecting and repairing leaks is one of the main components of water conservation. Old or poorly constructed pipelines, inadequate corrosion protection, poorly maintained valves and mechanical damage are some of the factors contributing to leakage.

Water loss from a water distribution system is a significant factor affecting water delivery to customers. Water loss can be either apparent losses due to meter inaccuracies or unauthorized consumption, or real losses due to leakage at water service lines.
