<\/div>

The Housing and Development Board<\/a> (HDB) and Public Utilities Board<\/a> (PUB) have completed the main construction works on Singapore’s first polder, creating 800 hectares of new land at Pulau Tekong.\u00a0This reclaimed area, about double the size of Toa Payoh, sits 1.2 metres below mean sea level, defended by a ten-kilometre coastal dyke standing up to six metres high.<\/p>\n

The completion of the Pulau Tekong polder project represents a subtle but significant shift in how we confront land scarcity, using a Dutch-inspired method that’s both environmentally responsible and economically sound.<\/p>\n

    The concept comes straight from the Netherlands, where they’ve been masters at this sort of thing for centuries. Basically, polders are areas of land that sit below sea level, protected by a system of dikes, drainage networks, and pumping stations that keep the ocean from reclaiming what was once its territory.<\/p>\n

    Unlike the traditional method of reclaiming land from sea which requires vast quantities of imported sand, the polder concept cuts sand use by nearly 50%. What\u2019s more, the project reuses over ten million cubic metres of clay excavated for creating a stormwater pond (more on this below).<\/p>\n

    This method offers a huge advantage for Singapore’s economy, which imported 14.6 million tonnes of sand in 2010 alone, ranking it the world\u2019s largest importer. That’s not just good for the budget; it’s brilliant for sustainability too, especially when countries around us are getting increasingly protective of their sand exports.<\/p>\n

    Dutch expertise meets Singapore innovation<\/h2>\n

    We did not embark on the polder experiment in isolation. Since 2008, HDB has worked alongside Dutch water institute Deltares, adapting centuries-old Dutch knowledge for local use. Technical advisors included Professor Kees d’Angremond, Deltares, and Royal HaskoningDHV in partnership with Surbana Jurong.<\/p>\n

    A Dutch-led environmental assessment found minimal impact on nearby marine ecosystems. The project represents a thoughtful blend of tried-and-tested European flood defences with the country\u2019s tropical reality. The partnership focused as much on ecological stewardship as engineering prowess.<\/p>\n

    Water management was central to the project. Here’s where things get really interesting from a technology perspective. Because this land sits below sea level in a country that sees some serious rainfall, managing water becomes absolutely critical. The polder features a 45-kilometre drainage network that would make any urban planner weep with joy!<\/p>\n

    The polder\u2019s stormwater pond covers 116 hectares and stores up to five million cubic metres of water\u2014roughly the volume in two thousand Olympic-sized pools. When this pond fills up, two sophisticated pumping stations kick into action to channel excess water safely out to sea.<\/p>\n

    But what really sets this apart is the monitoring system. PUB has installed over 170 CCTV cameras and more than 260 sensors throughout the polder to keep tabs on everything from water levels to the structural integrity of the coastal dike. It’s all controlled remotely from both an on-site control centre and PUB’s main operations hub back on the mainland.<\/p>\n

    The dyke itself uses natural grass and stone barriers to absorb wave energy and resist erosion, meaning the defences remain robust even as seas rise or monsoons intensify. The polder tackles dual threats: rising tides and heavier rainfall. The coastal dyke is built to be raised higher as needed, future-proofing the system against sea level changes.<\/p>\n

    Military training gets new territory<\/h2>\n

    The expanded polder will serve the Singapore Armed Forces, freeing up mainland land for homes and civilian amenities. Defence Minister Ng Eng Hen highlighted that the ten-kilometre extension enables more realistic and advanced training scenarios away from residential areas.<\/p>\n

    This move aligns with ongoing military modernisation. As defence needs grow more complex, having a dedicated offshore space allows for a wider range of training, benefiting both security and land use planning.<\/p>\n
