With water resources increasingly stressed due to climate change and growing populations, water utilities must become water-efficient throughout the entire supply process. By employing improved methods of water auditing and loss control, water utilities have potential to reduce the large volumes of treated water that are lost to leakage, as well as to provide incentives to customers to optimize their water consumption. Water Loss Control, water efficiency practices of water suppliers, is an emerging field of practice that should be better incorporated into the drinking water utility industry in order to ensure efficiency of safe drinking water, which is the backbone of civilized society. Links are provided to other resources to learn more about utility water loss control and some water providers who have worked to reduce water loss.
