Abstract: To mitigate the sufferings of the local residents from water-shortage for their daily life in some villages and towns of western Liaoning province, China Geological Survey has carried out a comprehensive project on groundwater investigation, exploitation, and utilization since 2004. Several water supply works have been progressed successfully. This paper presented types of the groundwater-bearing structures in the region and their unique characteristics in terms of hydrogeology. These have been proven to play a fundamental role in locating effective water supply works. Some experiences for locating the water supply works based on the nature of these water-bearing structures were introduced.
