Marina Barrage,
|
Overview |
The Marina Barrage is a tidal and flood control barrier that has been constructed across the mouth of the Marina channel at a cost of $226 million. Opened in November 2008, it has turned the waters of the Marina basin into an inland reservoir, Marina Bay now has a stabilised water level with no tidal fluctuations.
In this way the scheme is unique in that it is designed to achieve three aims:
The Singapore Marina Barrage comprises of nine numbers of 26.8-metres-long hydraulically operated steel gates, built across the 350m wide Marina Channel to keep out sea water. Under normal conditions, the steel gates will remain closed to isolate the reservoir from the sea. During heavy rain, the steel gates will open to release excess storm-water to the sea when the tide is low. However, when it is not possible to do so during high tide, an enormous pumping station capable of pumping up to 280 cubic metres per second will pump out the excess storm-water into the sea. The construction of the Marina Barrage Project was awarded to Koh Brothers Building & Civil Engineering Contractor Pte Ltd at a cost of $226 million. The instrumentation and monitoring was provided by CPG Laboratories with the supply of the In-Place Inclinometers and piezometers from Geomotion. These were linked to Campbell CR1000s with Geomotion I-Site data presentation software to provide the control and alarm functions. The barrage was a vision mooted in 1987 by then Prime Minister Lee Kuan Yew. With a catchment area of 10,000 hectares (about one sixth of Singapore) it is the largest water storage in Singapore storing 10% of current water demand. |
