Built across the mouth of Marina Channel, Marina Barrage creates Singapore's 15th reservoir, and the first in the heart of the city. With a catchment area of 10,000 hectares, or one-sixth the size of Singapore, Marina catchment is the island's largest and most urbanised catchment. Together with two other new reservoirs, Marina Reservoir increased Singapore's water catchment from half to two-thirds of the country's land area in 2011.

Water Supply

Marina Barrage is a dam built across the 350-metre wide Marina Channel to keep out seawater, forming Singapore's first reservoir in the city and 15th reservoir. Marina Reservoir, together with Punggol and Serangoon reservoirs, increased Singapore’s water catchment area from half to two-thirds of Singapore’s land area in 2011.

On 20 November 2010, Marina Reservoir was commissioned by the late Mr Lee Kuan Yew (the First Prime Minister of Singapore) as a freshwater reservoir, augmenting Singapore’s water supply for generations to come. Desalting had begun in April 2009 through natural replacement by rainwater.

Local catchment water is one of the Four National Taps, with the other three being imported water, NEWater and desalinated water.

Flood Control

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 will be activated 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

As the water in Marina Basin is unaffected by the tides, its water level will be kept constant all year round. This is ideal for all kinds of recreational activities such as boating, kayaking and dragonboating etc.
