Alkaff Lake, situated in the new Bidadari estate, is a first-of-its-kind multi-functional drainage infrastructure for stormwater management, enhancing flood protection for Bidadari estate and the surrounding areas. In dry weather, it looks like a regular lake and forms part of the recreational and aesthetic community space for the public. During heavy rainfall, it plays an important role in controlling stormwater runoff.
Alkaff Lake incorporates PUB’s Active, Beautiful, Clean Waters (ABC Waters) design features such as terraced wetlands and swales, which are integrated with our drainage infrastructure where feasible to create more liveable spaces that bring the public closer to water. Visitors can take in the panoramic view of the cascades and lake from the nest shelter or the large viewing deck which extends over the water.
Cascades
Terraced wetlands
To ensure good water quality in the lake, the terraced wetlands and swales help to cleanse and filter pollutants from stormwater runoff
Aerators
Gross Pollutant Traps (GPT) are installed to trap litter and silt that are accumulated in the runoff, while aerators within the lake improve water circulation and increase the amount of dissolved oxygen in the water
