Projects are part of ongoing drainage improvement programme to increase flood protection


PUB, the national water agency, is embarking on four new drainage projects as part of its ongoing drainage programme to increase flood protection.  The projects include work at Marymount Road, Queen Astrid Park, Benoi Road and Wan Lee Road.


Works at Marymount Road will commence in June 2012 and will entail the construction of a new 165m-long, 2.5m-wide box culvert (i.e. a drain that runs under the road) at the junction of Marymount Road and Bishan Street 21.  The new box culvert will run alongside an existing 165m-long, 6.4m-wide box culvert and will alleviate floods by improving the flow capacity of the drainage system serving the area.  As excavation on the road will be carried out, traffic will be diverted in stages to facilitate the construction of the new box culvert.  Inconveniences will be kept to a minimum as the number of lanes will remain the same and passable to motorists at all times. This project is expected to be completed by December 2013.


PUB will also be carrying out refurbishment work on old drains at Benoi Road and Queen Astrid Park, along with road raising work at Wan Lee Road.  These projects will commence in August 2012 and are expected to be completed by August 2013.


Ongoing and recently completed projects

Apart from the upcoming projects, 29 drainage projects are currently being carried out across the island.  These include projects at Derbyshire Road, King’s Road, Meyer Road, Rochor Canal Road, Spottiswoode Park Road and Syed Alwi Road.


Besides improving roadside drains, expansion works at several canals are also ongoing. They include Alexandra Canal (from Zion Road to Kim Seng Road), Bukit Timah First Diversion Canal (from Jln Kampong Chantek to Maple Ave), Geylang River (from Dunman Road to Guillemard Road) and Rochor Canal (from Jalan Besar to Crawford Street).


The projects will be progressively completed from the third quarter of 2012 to 2014.


Among the drainage improvement work already completed this year to alleviate flooding, are works at Mandalay Road, Hua Guan Ave and Sian Tuan Ave, as well as road raising work at Balmoral Road, Bedok Garden and Telok Kurau.
