What is the acceptable percentage of water loss in a water system?

The acceptable percentage of water loss in a water system is generally considered to be in the range of 10-15%. This figure is important as it reflects the efficiency and integrity of the water distribution system. A percentage within this range indicates that the system has a reasonable balance between operational losses—such as leaks or inefficiencies—and the amount of water that is distributed and accounted for.

Water loss can occur due to various factors, including leaks in pipes, unauthorized use, or metering inaccuracies. A percentage of water loss higher than 15% often raises concerns about the system's management, maintenance, and infrastructure quality. Water systems aim to minimize losses to ensure sustainability, reduce treatment and pumping costs, and maintain service delivery to customers effectively. By keeping water loss within the 10-15% threshold, utilities can work towards improved water conservation efforts and financial viability.
