Land Reclamation in Singapore
Reasons for Land Reclamation
Large-scale land reclamation has been undertaken in different parts of Singapore since the 1960s. This is necessary because of
More land has been made available for
By 1990, the total land area of Singapore was 633km square. This was an increase of 51.5km square, which made up 8.9% the total land area. With continuing land reclamation, land area in Singapore will increase by about another 100km square by the year 2030. There are, however, constraints as to how much more land the country can reclaim. Two limiting factors have to be considered.
Land Reclamation Agencies
Other than the land reclamation of the offshore islands of Pulau Bukum, Pulau Bukum Kechil, Pulau Ular and Pulau Ayer Chawan by two private oil companies, land reclamation is undertaken by three public agencies in Singapore. They are
Among some of the future large-scale reclamation works are
Land reclamation has modified the coastline of Singapore, extending it seawards, especially on the eastern, north-eastern and western parts of the island, and changing it quite beyong recognition. Large coastal areas have also been starightened by the building dykes across estuaries, particularly in the west coast across the estuaries of Tengeh, Poyan, Murai and Sarimbun. Many offshore islands have become larger. Future reclamation will add more changes to the configuration of Singapore.
Method of Land Reclamation
The landfill mothod is used to reclaim land from the coast and the swamps in Singapore. It is also used in reclamation works involving the merging of islands. One such project is the amalgamation of Pulau Sakra and Pulau Bakau into one big island called Pulau Sakara, which is ten times the size of the two former islands.
In the early years, the fill materials evacuated from the hills in Bedok, Siglap, Tampines and Jurong were used for filling the reclamation areas. In recent years, sea sand obtained from the seabed is the main source of fill materials for reclamation. The reclamation contractors import the sea sand from the neighbouring countries such as Indonesia.
