Joint Press Release by MND & HDB: HDB to adopt new land reclamation method at Pulau Tekong
Singapore will reclaim land through the development of a polder at the north-western tip of Pulau Tekong. This innovative, cost-saving method, to be used for the first time here, will be adopted by the Housing & Development Board (HDB) for the upcoming land reclamation project. This was announced by Mr Lawrence Wong, Minister for National Development and Second Minister for Finance during his visit to the polder site at Pulau Tekong this morning.
2 Unlike the traditional method of infilling with sand, this “empoldering” method involves creating a tract of reclaimed land from the sea or a surrounding water body, by constructing a dike and a network of drains, water pumping systems and canals. It will substantially reduce the amount of sand needed for land reclamation, and reap savings on upfront construction costs.
Please refer to the illustration below for a comparison of the traditional infilling method and polder development method.

3 The polder will be protected from the sea by a dike measuring 10 kilometres long, up to 15 metres wide at its crest, and will stand at about 6 metres above sea level. In designing the safety provision of the dike, HDB has drawn on the vast experience of the Netherlands, which currently has the world’s highest standards for dike safety, to ensure long-term safety of the polder land.
4 HDB worked closely with Professor Kees d’Angremond of the Netherlands, an authoritative figure on polder development and a long-time Adviser to Singapore on reclamation works, on the design of the polder development at Pulau Tekong to ensure that it is cost-effective, safe and environmentally-sensitive.
5 An environmental study has also been carried out to ensure that there will not be significant impact on the surrounding marine environment and marine life. The study has found that the environmental impact due to the development of the polder would be minimal. In addition, surrounding areas where mangroves and other plant life are present would be conserved and protected.
6 Tender for the polder project is expected to be called by end 2016, and construction work will commence in end 2017. When completed around 2022, it will add an additional 810 hectares of new land to Singapore.
