Water leaks in the distribution network


Ensuring the integrity of a water distribution network with hundreds kilometers of pressure pipelines laid underground sometimes in corrosive soil and ground water is practically impossible. Leaks in the water distribution network are a permanent element of the network operation and maintenance. Drinking water losses during transportation pose a tangible economic damage to water providers, contribute to underground water level increase, and sometimes produce an adverse environmental effect. The operation personnel carry out continuous work on eliminating water leaks. Water leak control in the distribution network is an essential part of operation and maintenance. The information on water leaks amount and water losses in certain countries of the world is presented. Detailed description of the experience in preventing leaks in the Tokyo water distribution network with the lowest in the world water leak level is presented.
