Smart Pipeline Water Leakage Detection System

摘要

Water is an essential natural resource required for survival. Most of the area in the planet earth is covered with water. But only less percent of water is directly consumable by living beings. Transportation of such resource is made easy by means of manmade pipeline connections. Leakage constitutes a major loss of drinking water when supplied through pipeline systems. Introducing automated leakage detection systems would save huge amount of water globally. In developed countries water leakage is found using acoustic devices which uses vibrations or sound induced by the pressurized pipes. But in developing countries major leaks are found only when it is visible on the surface, this results in considerable amount of water getting wasted. Water leak detection by means of simple embedded system aids water conservation in a cost-effective way. The flow sensors can be used for detecting the leak and solenoid valves placed in different parts of the pipeline can obstruct the water flow until the defective part of the pipeline is repaired. And further, the leak occurred shall be informed to concerned authorities wirelessly by means of cloud based data logging. GPRS module enables data logging with the existing cellular network infrastructure. A prototype of the suggested system was implemented and tested with various scenarios and the results are presented in this paper. Water resource management is one of the key goals of any country in the world as water requirement is increasing steeply; involving automation in such systems will reduce human errors and will increase efficiency and thus decreasing the supply demand gap.
