The Water Supplies Department (WSD) is committed to ensuring the provision of a reliable and clean water supply for people in Hong Kong. Continuous effort in enhancing its water resource management systems, controlling water quality, securing reliable water supply and providing customer service are made over the years.


Developing new technologies to drive optimisation

To further improve the water quality monitoring, staff in the WSD has developed an innovative Biosensing Alert System with the help of zebra fish that have genetic composition very similar to that of humans and with high sensitivity to the environmental changes. This new system is a product of integrating biological, IT and telecommunication technologies, employing powerful camera and tailor-made computer programming. It conducts 24-hour monitoring on activities of zebra fish in a specially designed aquarium.

When the system detects any abnormal activities or distribution of the zebra fish, a warning is issued alerting the team immediately that the water may be contaminated. At the same time, the auto-sampler begins taking water samples at preset intervals for further toxicity test. The toxicity test is highly accurate with a rapid diagnostic capability that can test for over 1,000 harmful substances in water within 60 minutes.

The new system has not only brought about higher efficiency in water quality monitoring but also significantly reduced the consumption of chemicals, doing big service to environmental protection.

Promoting water conservation

Fresh water is a precious natural resource. To increase public awareness of water conservation, the WSD has organised a wide range of programmes from producing a liberal studies curriculum for school on water conservation, hosting competitions, conducting household water consumption surveys and campus water audits to implementing the Water Efficiency Labelling Scheme.

Since its opening in 2012, the WSD's Water Resources Education Centre has provided guided tours to schools and other non-profit organisations to introduce to them the importance of water conservation. During these tours, visitors will learn about what they can do to conserve water through seeing exhibition materials, demonstration by centre staff and interactive games. Students who have visited the centre are also encouraged to conserve water in their daily life and promote water conservation among their peers.

The WSD has worked with dedication in ensuring clean water supply and promoting water conservation, quietly supporting the economy and prosperous development of Hong Kong.
