Marina barrage Done By : Karen Lim Reg. No. : 8 Class : 2B
Marina Barrage . Built across the mouth of the Marina Channel, the 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, the Marina catchment is the island’s largest and most urbanised catchment.
Water Supply . Marina Reservoir combines with the future Punggol and Serangoon reservoirs will increase Singapore's water catchment areas from half to two-thirds of Singapore's land areas. Desalting had begun in April 2009 through natural replacement by rainwater. Marina Reservoir will meet more than 10% of Singapore's current water demand.
Flood Control . The 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, JalanBesar 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 the 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, windsurfing, kayaking and dragonboating etc.
Green Roof . The iconic Green Roof uses 100% recycled plastics and eco-friendly drainage cells. This large rooftop garden also provides natural heat insulation for the building. The grass and the soil shields the building from the sun and reduces maximum surface temperature by 19˚C.
Solar Park . The Solar Park is one of the largest collections of solar panels in Singapore. The 405 panels generate about 50% of the daytime electricity needed for indoor lighting and power points at the barrage.
Sustainable Singapore Gallery . The facility houses a gallery highlighting Singapore’s efforts and achievements in maintaining a sustainable environment. Through interactive multi-media displays, exhibits and games, it educates the public about important environmental and water issues.
First reservoir in the city comes alive . 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.
