Singapore reclaims 800ha of land at Pulau Tekong with completion of first polder
Polders are tracts of land that lie below sea level and are reclaimed through the building of dikes, drainage canals and pumping stations.
The polder - twice the size of Toa Payoh - will be used for military training.
This is the first time Singapore has reclaimed land below mean sea level.
Construction was completed using the empoldering method, which uses 50% less sand compared to traditional land reclamation processes.
A 10km-long coastal dike, a type of barrier, has been built along the perimeter of the polder to keep seawater out.
Beneath the polder lies a series of pumps and a 45km-long drain network to assist with the flow of rainwater.
