About the Project:
The new Student Facility Block of Hwa Chong Institution, like many developments in
Singapore, has limited land area. So in order to treat the nutrient-rich runoff from the
roof garden, a cascade of vertical bioretention basins is designed on the facade of the
Runoff from the roof is channelled through downpipes to the upper basins. Excess water overflows to the lower ones. These bioretention provide both vertical greenery as well as stormwater quality treatment.
A special feature in this project is a bioretention basin that has a glass wall. This glass wall allows students to see the substrate profile and observe the filtration and biological treatment at work.
