On average, Singapore receives 100 inches of rain annually. Singapore Public Utilities Board hired CDM (a consultancy firm with world-wide operations) for managing their water resources. CDM built a complex, low-level dam that has increased water supply, improved the water quality, arrested overflow and provided flood control mechanism.
The 1,150-foot-long Marina Barrage is designed in a way that the gates normally remain closed to separate the reservoir from the ocean. During extreme monsoon conditions, when the tide is low, they work in harmony to release excess flows from the Marina. Apart from this basic function, the barrage and pumping station also alternate to provide stable water levels for a new 600-acre freshwater reservoir in downtown Singapore.
The additional facilities created by CDM include a 13-megawatt power station and a two-story interactive tourist center complete with a circular glass theater situated inside a botanical park. The bridge has thus supported economic development, improved the lifestyle of people in the area and provided recreational opportunities in Singapore's urban center.
