Water Leak Detection and Shut-Off System on Water Distribution Pipe Network Using Wireless Sensor Network

The growing clean water needs in Malang City, East Java, Indonesia encourages the government to improve the performance of water supply services, including minimizing the amount of water loss distributed to customers due to pipe leakage. Water flow monitoring and leakage systems based on the wireless sensor network could be used to present information on the water flow in a pipe and to shut-off a valve if there is a leak. The data then could be sent to the server to be displayed on a website. The developed system was able to read the water volume with an average error value of 2.23% of the measured total volume and determine the leakage pipeline with a leakage measuring limit of 30mL/sec. The system also had a maximum transmission distance between nodes of 170 meters and it was able to present monitored nodes data into a website. With a small error value and the large transmission range, it was expected that the pipeline leak could be detected sooner and precautionary measures could also be taken.
