Singapore to Build Dutch-Style Sea Barriers to Guard Against Rising Waters

From the 2030s, Singapore will begin constructing three massive coastal barriers along its southern coast to shield the city from rising sea levels and storm surges. Announced by national water agency PUB, the Dutch-inspired structures—similar to Rotterdam’s Maeslant Barrier—will function like arm-like gates, opening and closing depending on weather conditions. The gates can take two hours to close and may remain shut for several days during severe storm surges, which here could last up to five days. By 2100, sea levels around Singapore could rise by up to 1.15m, with storm surges adding 3m to 4m. The planned barriers will connect the mainland to Pulau Brani and Sentosa, doubling as possible causeways and public spaces. Experts say they could also serve educational and recreational purposes, much like Marina Barrage. PUB is also studying extending such defences to Jurong Island, Tuas shipyards, and Pasir Panjang Terminal.
