Marina Reservoir

First reservoir in the city comes alive

The Marina Reservoir is now ready to be used as a freshwater reservoir, augmenting Singapore’s water supply for generations to come. The Marina Reservoir can meet about 10% of Singapore’s water needs. Desalting had begun in April 2009 through natural replacement by rainwater.

Water from local catchments is a pillar of Singapore’s water sustainability strategy, along with imported water, ultra-clean, high-grade reclaimed water branded as NEWater in Singapore, and desalinated water. Collectively, these four sources of water are known as the 'Four National Taps', a long-term water supply strategy to ensure a diversified and sustainable water supply for Singapore in the years to come.
Urban stormwater collection

Singapore has two separate systems to collect rainwater and used water. Rainwater is collected through a comprehensive network of drains, canals, rivers, stormwater collection ponds and reservoirs before it is treated for drinking water supply. This makes Singapore one of the few countries in the world to harvest urban stormwater on a large-scale for its water supply.
Why it is important to keep the drains, canals and waterways clean?

Marina Barrage has been PUB's most challenging reservoir project to date as it is fed by five rivers that run through the heart of Singapore. It is a reservoir in the city. This makes the reservoir much more susceptible to pollution. Moreover, it is located in the heart of downtown Singapore close to the Central Business District and many key attractions. Therefore, any pollution will therefore be highly visible.

With those considerations in mind, many pollution control and mitigation measures were put in place prior to the completion of Marina Reservoir. With the creation of Marina Reservoir and two other reservoirs, Punggol and Serangoon,
Singapore’s water catchment area increased from half to two-thirds of Singapore’s land area in 2011. The Marina Barrage project is an example of how a water project has been integrated not just within the water cycle, but has been planned and executed as an architectural icon and a community project for the city.
Daily Maintenance

PUB conducts clean-up in the reservoir from 7am to 6pm daily to ensure that it is free of litter.
