SINGAPORE - National water agency PUB started distributing inflatable flood bags and portable flood barriers to homes in Sunset Way and Sunset Drive on Monday afternoon.

This is a precautionary measure after a landslide last week created a blockage in the nearby Ulu Pandan Canal. 

These flood protection devices can be set up quickly during heavy rain, to prevent floodwaters from entering homes, PUB said in a statement on Facebook.

"We have also engaged building owners in the vicinity to assist them with flood protection preparation," the agency added.

Inflatable flood bags are alternatives to traditional sandbags and filled with a material that inflates when there is contact with water, while the self-anchoring flood barrier creates a dam to redirect floodwater.

Meanwhile, the Housing Board said in a separate Facebook post on Monday that works to widen the channel in the canal have started following lab tests on soil samples to determine the strength and condition of the dislodged soil.

“We have ascertained that we can safely widen the channel from the current 1.5m to 3.5m, to further improve water flow and mitigate flood risk,” said HDB.

“Works to widen the channel have started and expected to complete soon.”

These follow a landslide last Friday near the Clementi NorthArc construction site in Clementi Avenue 6, which caused damage to the Ulu Pandan Park Connector and led to soil displacement into the Ulu Pandan Canal.

The site has been cordoned off for public safety, with residents told to stay clear of the area for now.

A section of the park connector which stretches between Boon Lay Way and Clementi Road will remain closed.

The authorities had said earlier that recovery works to stabilise the site and safely remove the dislodged soil in Sungei Ulu Pandan would take time.

PUB on Monday said that with rainy weather expected in the first half of September, the areas upstream of the canal blockage may experience higher flood risk in the event of heavy rain.

The agency has also increased its deployment of quick response team vehicles, which are on standby in the upstream locations, so they can quickly respond to potential flash floods and provide assistance.

It added that it is also closely monitoring the rain forecast and water level sensors in the canal, and will support National Parks Board to close the Ulu Pandan Park Connector for public safety when necessary.

"We will like to remind the public to avoid using the park connector during heavy rain," PUB said.

"Should a flash flood occur, please remain on high ground and avoid walking through floodwaters."

Senior Minister of State for Foreign Affairs and National Development Sim Ann said in a Facebook post on Monday: “PUB has started distributing flood protection devices such as portable barriers and inflatable flood bags to some of our residents in the Sunset Way area. This is because the amount of dislodged soil in Ulu Pandan Canal increases flood risk.

“Drainage has been progressively improved in the Sunset Way neighbourhood in recent years, but it is still one of the closest areas to the incident site. Of course, we hope these devices won’t need to be used, but it is good to be prepared. Thank you, PUB!”

It was reported last week that one passer-by suffered minor injuries in the landslide incident and was attended to at the site. The injured man is now resting at home.

No other injuries were reported.
