Singapore: Groundwater monitoring to be expanded

PUB, Singapore’s National Water Agency, is planning to expand its groundwater monitoring network. It will be calling two tenders over the next few months for the installation of additional monitoring wells and sensors to provide a better understanding of the presence of groundwater in the city-state. PUB has been monitoring groundwater levels across western Singapore, in an area known as the Jurong Formation, through a network consisting of 18 monitoring wells. PUB plans to further its monitoring efforts to include the Old Alluvium in eastern Singapore and Jurong Island, and will install 30 to 40 monitoring wells. In addition, there are plans to insert sensors into all the monitoring wells to track water level fluctuations, enabling island-wide monitoring of Singapore’s groundwater situation.
