Leak Detection Cost-effective and Beneficial

摘要

One of the major contributors to water loss is unknown underground leaks in the distribution system, most of which go undetected for long periods of time. Aggressive leakage control programs can usually locate 50-75 percent of unaccounted-for water, which is the difference between the water delivered to the distribution system and the amount of water sold to customers. Eddie Harris, executive director of the Wilson County Water Authority in Lebanon, Tenn., said, "Our unaccounted-for water was [more than] 45 percent, and we needed to take action. We implemented a leak detection program throughout the entire distribution system, reducing our unaccounted-for water to about 10 percent. The direct result was a reduction of 35 percent in the cost of the water we were purchasing from our supplier. It had a tremendous impact on reducing our operating costs."
