Conserve Water Using the Behaviour Activated Showerhead

Why Conserve Water?

Water is a crucial natural resource on our planet. Of all the water that exists on our planet, less than 2.5% is freshwater—water that can be used for daily human activities that does not contain a high concentration of salts—of which less than 1% is accessible to humans. With population and economic growth in recent years, the demand for freshwater resources has increased worldwide and in Hong Kong.

With no natural lakes, large rivers, or groundwater reservoirs in Hong Kong, our city makes a strong effort to ensure there are sufficient freshwater resources for our community. Currently, Hong Kong’s freshwater comes from two main sources—imported water from Dongjiang and local rainwater catchments.

We can all help conserve freshwater resources by taking action in our daily lives:

• Take quicker showers (average duration is 6.7mins in HK, recommended target is 4 mins) 
• Use a Behaviour Activated Showerhead or other water saving devices
• Turn off the tap when brushing your teeth, washing your face, and shaving

What is the Behaviour Activated Showerhead?

The behaviour activated showerhead incorporates an innovative LED lighting system that changes colours as a gentle reminder of the water usage during the shower. The water consumption data will be available on the Internet of Things (IoT) data platform for the university community to access. The infrastructure aims to raise the community awareness regarding the responsible consumption of water.

The light on your showerhead will change colours based on your water usage throughout your shower. Try to avoid the red light as much as possible!
