Singapore restores 1920s lake for flood control and wildlife habitat

AI-summarized · Neutrality-checked

Singapore’s Public Utilities Board (PUB) integrated a 1.8-hectare stormwater retention pond, named Alkaff Lake, into the new Bidadari residential estate to pay homage to the historic 1929 Alkaff Gardens. Designed to manage runoff from 43.5 hectares of land, the lake can temporarily hold 40,000 cubic metres of water during intense rainfall to reduce pressure on the downstream drainage system. The project utilized the 'Active, Beautiful, Clean Waters' approach, incorporating wetlands and greenery to treat stormwater while providing recreational space for residents.

Consequences

The lake will serve as both a public recreational area during dry weather and essential flood-control infrastructure during heavy storms. By integrating drainage systems into the landscape, the project allows for effective water management in a space-constrained urban environment while fostering biodiversity.
