This paper presents the use of Zigbee-Based wireless sensor network (WSN) for leakage detection in
underground water transporting pipelines. It has been implemented on a laboratory model of an underground
pipeline having length of 20 metres. Sensor nodes configured in mesh topology were distributed over the length of the
pipeline. The gateway node has been placed at some distance from the sensor nodes and was programmed to acquire
data for soil-moisture, soil-temperature and GPS data at intervals of 5 seconds. The system has been programmed is
such a way that when the change in soil temperature or soil moisture as read from any sensor exceeds a pre-set
threshold an alarm or warning signal is generated so that the corrective action can be taken on time.
