ST 18 June 2010
Blocked Drain Blamed for Orchard Flood (on 16 June 2010)IT WAS just a single drain, about the width of an SBS bus. But it was so badly blocked by debris that it triggered the flooding of Orchard Road on Wednesday.
The critical culvert, at the junction of Tanglin and Orchard roads, drains into two parallel channels flowing under Orchard Road - a drainage system called the Stamford Canal.
The first heavy downpour of the morning had carried debris and vegetation into the 2.7m by 2.7m culvert, starting a chain of events that led eventually to the flash flood.
It was choked where it drained into the side of Delfi Orchard, so water was directed only into the side along Forum the Shopping Mall.
When a second intense rainstorm the same morning added more water to the drains within a short period of time, the canal overflowed and water gushed up to the surface of Orchard Road, causing the worst floods there in 26 years.
Worst-hit was the junction of Scotts Road and Orchard Road, the lowest-lying part of the area. Near the intersection, shops at Liat Towers and the Lucky Plaza basement were flooded.
Although national water agency PUB alerted the traffic police when the sensors at the start of each Stamford Canal channel indicated water levels were at 75 per cent, the water level rose too abruptly to get the alert out to shopkeepers.
At a press conference yesterday, the PUB said the heavy rains were responsible for sweeping the debris into the drain.
It was last checked about three months ago and was not blocked before Wednesday's storm, said Mr Yap Kheng Guan, director of PUB's 3P (Public, Private and People) Network.
After the flood on Wednesday had receded, PUB officers combed the canal for hours, and at 10pm that night found a third of the culvert still blocked.
To fix the problem, the PUB would now conduct checks more often than every three months, he said. It would also install grates in flood-prone areas to prevent debris from being swept into the drains.
Asked why there were no debris traps already installed in a known flood-prone area, he said the existing canal had been 'serving us very well'.
Rain this heavy had occurred twice before, in August last year and January 2008, without severe flooding, so the Stamford Canal has the capacity to handle such a volume of water.
What was unusual about Wednesday's storm was its intensity and its two peaks, he said. The first peak could have brought a certain amount of debris, and there was no way for PUB officers to safely check and clean it out. The next peak soon after might have brought even more debris.
'This is a learning experience for us,' Mr Yap said. 'Perhaps when we're dealing with a storm like this, we have to do something differently.'
In the long run, more sensors would be added to monitor water levels, he said. They would also serve as an early warning system similar to that now in place at Upper Bukit Timah.
Following flash floods in the area last November, flood sensors were installed which will trigger SMS alerts to condominium managements if the water level in the Bukit Timah canal reaches a certain height, so residents can move their cars and other property to safety.
Ms Lee Bee Wah, MP for Ang Mo Kio GRC and deputy chairman of the National Development and Environment Government Parliamentary Committees, said the flooding was a 'timely wake-up call' that something more needs to be done to prevent a similar occurrence.
On Wednesday morning, 101 mm of rain fell over central Singapore in less than three hours. The average rainfall for the entire month of June is 162 mm.
National University of Singapore climate expert Matthias Roth said that though June is usually dry, heavy rain is always a possibility in places located close to the equator.

“It was last checked about three months ago and was not blocked before Wednesday's storm, said Mr Yap Kheng Guan, director of PUB's 3P (Public, Private and People) Network.“
If it was checked about 3 months ago, it was not blocked 3 months ago
Unless it was checked on Tuesday, then we can be sure it was not blocked before Wednesday storm -
show picture as proof please.
-
Mr Yap, dragg ask you to show picture as proof
-
since now PUB have volunteered to say there was a mistake made, so who to blame and ask for compensation now?
