Built across the mouth of Marina Channel, Marina Barrage (MB) is a dam built across the 350-metre wide Marina Channel to keep out seawater, creating Singapore’s 15th reservoir, and the first in the heart of the city.
With a catchment area of 10,000 hectares, Marina catchment is the island’s largest and most urbanised catchment. Together with two other reservoirs, Marina Reservoir has increased Singapore’s water catchment from half to two-thirds of the country’s land area.
Marina Barrage is part of a comprehensive flood control scheme to alleviate 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 are activated to release excess stormwater into the sea when the tide is low. In the case of high tide, giant pumps can drain excess stormwater into the sea.
Marina Barrage is the vision of the late Mr Lee Kuan Yew (the first Prime Minister of Singapore) more than two decades ago when he envisaged damming the mouth of the Marina Channel to create a freshwater reservoir.
Marina Barrage, a project commissioned by PUB, was officially opened on 31 Oct 2008 by Mr Lee Hsien Loong, Singapore's Prime Minister.
Desalting started in April 2009 through natural replacement by rainwater. On 20 November 2010, Marina Reservoir was commissioned by the late Mr Lee Kuan Yew as a freshwater reservoir, augmenting Singapore’s water supply for generations to come.
