Water Conservation

Rainwater harvesting system 

As part of our efforts to boost water resource efficiency in public housing, we will introduce the rainwater harvesting system which was successfully piloted using Membrane Technology at our Centre of Building Research. The new system reduces the usage of potable water for block washing at void decks, refuse chutes, and corridors. 

Advantages:

• Saves up to 850m³ of potable water annually for block washing
• Requires minimal maintenance
• Lowers energy consumption
