Singapore's latest downtown icon
The Marina Barrage is built across the mouth of the Marina Channel. It is Singapore's 15th reservoir and also the 1st in the heart of the city. The Marina Barrage is the island's largest and most urbanised catchment ,with a catchment area of 1/6 of Singapore (10000 hectares).
Water Supply
The Marina Barrage is a dam built across the 350-metre wide Marina Channel to keep out seawater. The reservoir would be combining with the future Punggol and Serangoon reservoirs. It will increase Singapore's water catchment areas from 1/2 to 2/3 of Singapore's land areas.
On 20 Nov 2010, the reversoir was crowned by Minister Lee Kuan Yew as a freshwater reservoir, boosting Singapore's water supply for generations to come. In April 2009, desalting began through natural replacement by rainwater.
Marina Reservoir will meet more than 10% of Singapore's current water demand as it is one of the pillars of local water supply.
Flood Control
The Marina Barrage is part of a comprehensive flood control scheme to sustain flooding in the low-lying areas in the city such as Chinatown, Boat Quay, Jalan Besar and Geylang.
During heavy rain, the series of nine crest gates at the dam will be propelled to release excess storm water into the sea when the tide is low.
In the case of high tide, giant pumps which are capable of pumping an Olympics-size swimming pool per minute will drain excess storm water into the sea.
Lifestyle Attraction
The water level of Marina Basin will be kept constant all year round as the water is unaffected by high tides.
This is absolutely excellent for all kinds of sporting activities such as canoeing, dragon-boating and kayaking.
