Built across the mouth of Marina Channel, Marina Barrage creates Singapore’s 15th reservoir, and the first in the heart of the city.
It is the vision of the late Mr Lee Kuan Yew (the first Prime Minister of Singapore) more than three decades ago when he envisaged damming the mouth of the Marina Channel to create a freshwater reservoir.
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 was officially opened on 31 Oct 2008. 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.
Marina Barrage is a multifunctional infrastructure that brings about three key benefits: source of water supply, flood control, and a venue for recreational and lifestyle activities.
Marina Barrage is a tidal barrier built across the 350-metre-wide Marina Channel to keep seawater out, creating the 15th reservoir in downtown Singapore. Water from local catchments is one of the Four National Taps, alongside imported water, NEWater and desalinated water.
Marina Barrage is part of a comprehensive flood control scheme to alleviate flooding in low-lying areas in the city such as Chinatown, Boat Quay, Jalan Besar and Geylang. During heavy rain, the series of nine crest gates 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 removes tidal influence from Marina Reservoir, allowing water levels to be kept relatively constant throughout the year. This creates ideal conditions for water-based activities such as kayaking, sailing and dragon boating.
The iconic Green Roof at Marina Barrage is also a popular destination for visitors, offering sweeping views of the Singapore skyline and a space for activities such as kite-flying and picnicking.
