Incorporated into the design is the concept of rainwater harvesting.

Rainwater from surface parking and on the soft landscaped Northern end of the site is channelled to subsurface drains which will reroute the water to the Southern end of the building, and then release it slowly back into the wetland via silt traps and French drains.

This ensures that the wetland will continue to grow and eventually thrive.

Similarly, rainwater from the roof slabs will be channelled via full-bore outlets to an attenuation dam on the Southern end of the site where it is used for the irrigation of the landscaping.

To further limit the reliance on potable water for irrigation of the landscaping, only indigenous planting has been chosen for the site.
