Paya Lebar, Singapore


To create an on-site non-structural stormwater detention tank system to slow down runoff, improve stormwater quality, reduce time and cost impact.


More than 7,000 units of Elmich’s VersiTank®  enveloped with geotextile were installed underneath a series of rain gardens to prevent solid particles from penetrating and clogging the stormwater filtration and management system. The filtered stormwater is temporarily stored in the approximately 980 mtanks to reduce flooding from peak flow of runoff during heavy rain occurences before being discharged into the Geylang River.
