PUB ABC Waters-compliant bioretention basins and naturalised channel edges treating stormwater.
The challenge
Deliver a treatment train that meets ABC Waters design standards and passes agency inspection first time, while surviving Singapore's storm intensity.
Our approach
We built bioretention basins, vegetated swales and rock-pitched edges to the PUB design guidelines, with a planting and soil-media regime tuned to the catchment.
The outcome
The treatment train passed agency inspection first time and has held up through monsoon flows.
