Novel stormwater management technology advancement and application in Singapore

Urbanisation has negative impact in both stormwater runoff quantity and quality. The replacement of green areas with impervious surfaces has resulted an increase in stormwater runoff quantity due to the reduction of evapotranspiration. As such, urban stormwater runoff is often characterised by elevated peak flow with increased velocity causing erosion in stormwater runoff receiving waterbodies. The removal of green areas also prevents stormwater runoff infiltration through the soil column which helps to remove pollutants such as phosphorus, nitrogen and suspended solids, preventing eutrophication in waterbodies and destruction of habitats. Traditional stormwater management system involves the use of drains and canals to convey stormwater runoff away quickly and effectively. Such system does not provide protection for receiving waterbodies from changes in stormwater quantity and quality. In view of the limitations of traditional stormwater management system, there has been a rise in the adoption of bioretention systems for stormwater management worldwide. However, the biorentention systems adopted in other counties have some limitations which would limit their wide application in tropical areas such as Singapore. In this talk, the research and development of novel bioretention systems in Center for Water Research, National University of Singapore will be covered. The application of novel bioretention technologies in Singapore for sustainable stormwater management will also be introduced.
