Global clean water supply remains a huge challenge around the globe. As estimated by UNICEF, by 2040, one in four of the world’s children under 18 will be living in areas of extremely high water stress. To ensure safe and resilient water supplies, HKU’s Centre for Water Technology and Policy (CWTP) addresses issues such as the region’s water resource management and water-use efficiency through interdisciplinary research and teaching.


CWTP conducts a wide range of projects which focuses on tackling water resource issues from water supply and demand perspective. The smart water auditing project helps domestic users reduce water consumption by using data to reinforce positive conservation behaviour. As for research, CWTP is investigating the feasibility of switching from seawater to reclaimed water for flushing in Hong Kong. They are also studying the water attitudes of various cities in China to establish a baseline for future water conservation campaigns in the region. 

CWTP teaches a variety of courses to ensure the student body has the opportunity to learn about water management. Their course “Water: The Next Oil?” equips students with a comprehensive understanding of the technologies relating to water supply and wastewater treatment systems in both developed and developing countries through the lens of ensuring access to water and sanitation for all.

The Jockey Club Water Initiative on Sustainability and Engagement (JC-WISE) continues to promote water-use efficiency through the concept of “Water Footprint”. Jointly launched by JC-WISE, CEDARS and the Sustainability Office, with involvement from campus catering outlets, “Water Wise Campus” is a campus-wide awareness campaign that aims to increase water conservation behaviour among students and staff. Catering outlets across campus display the “Water Footprint”, or the water intensity, of various dishes to encourage consumers to make environmentally conscious choices. JC-WISE also launched the “My River, My Community” Scheme, a series of expert-led field trips in Hong Kong to enhance participants’ ecological, social, cultural, and environmental knowledge of river basins.
