SDE4's uses a rainwater collection system combined with bioswales and on-site detention to provide partially for its non-potable water usage.
Bio Retention Basin
The bioretention basin helps SDE4 reharvest one-third of its rainwater runoff for irrigation and other non-portable demands of the building.
Active, Beautiful and Clean (ABC) Water Programme
SDE4 is an ABC Waters site, as it employs a combination of on-site retention and rainwater harvesting strategies to protect water quality and enhance biodiversity.
The water feature is only active when it rains - adding sound, texture, and movement to the landscape while becoming a pedagogical tool for teaching and research.
