Stormwater Management
The stormwater drainage system in Singapore is completely separated from the sewer system. It consists of 7,000 km of public roadside drains and about 1,000 km of major canals and waterways that are regularly cleaned of debris and maintained by private companies under performance-based contracts with PUB. This system has reduced the flood-prone area from 3,200 hectares in the 1970s to about 49 hectares today despite increased urbanization, which usually would have resulted in more floods. PUB plans to further reduce flood prone areas to 40 hectares by 2013. In the 1960s and 1970s widespread flooding was common in Singapore, especially in the city centre, which is built on relatively low-lying land. Nevertheless, flash floods caused by unusually heavy rains and blocked drains caused damage in 2010 and 2011.
