Currently, Singapore uses two separate systems to collect rainwater and used water. Rainwater is collected through a comprehensive network of drains, canals, rivers and storm water collection ponds before it is channelled to Singapore's 17 reservoirs for storage. This makes Singapore one of the few countries in the world to harvest urban storm water on a large scale for its water supply.










MARINA BARRAGE 
Marina Reservoir 

The 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 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.
 On 20 November 2010, the Marina Reservoir was commissioned by Minister Mentor Lee Kuan Yew 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.

As one of the pillars of local water supply, Marina Reservoir will meet more than 10% of Singapore's current water demand.
