Urban Water Systems R&D group (UWS-RD) is an interdisciplinary research group developing time reversal and imaging techniques to establish the next generation of urban water systems which are better designed, operated and managed.

We are located at the Department of Civil and Environmental Engineering of the Hong Kong University of Science and Technology.  

ABOUT US

​​We are dedicated to develop efficient, robust and high resolution diagnosis techniques for urban water systems based on the physics of time reversal of waves.

Our Research Objectives

  • To establish the scientific and engineering fundamentals of time reversal of wave in pipelines systems.
     

  • To explore pipeline material properties that enhance the resolution of time reversal imaging techniques.
     

  • To develop advanced experimental methodologies to enable the implementation of time reversal techniques in real urban water systems.

  • To envision the design of the next generation of urban water systems.

Importance and Impact

Urban Water Systems (UWS) are essential urban infrastructures and vital to sustain the life and the prosperity of our cities. Unfortunately, these systems are aging and more prone to defects and malfunctions. For instance, leaking pipes represent a substantial loss in potable water systems, and a potential contamination source in sewage force mains.
 

In this context, the development of cost-effective, non-intrusive techniques that allow for the rapid inspection and diagnosis of the systems would greatly benefit society. The benefits include not only water and energy savings but also the guarantee that the water delivered to the population meets water quality criteria.
