Foam at Pang Sua Canal mostly cleaned up

SINGAPORE: The huge clouds of foam that engulfed the Pang Sua Canal at Choa Chu Kang on Tuesday morning have been mostly cleaned up, said national water agency PUB.

At about 5pm, PUB said in a Facebook update that the foam, which is non—toxic and is bio—degradable, has been mostly cleared up.

The clean—up work started in the morning after the canal and the nearby park areas were hit by foam.

The foam made its way to the canal after the warehouse blaze in Upper Bukit Timah Road on Monday night.

The Singapore Civil Defence Force said the warehouse stored about 70 barrels of detergent—based concentrate, each holding about 200 litres of the detergent.

About 40 barrels were damaged, causing the detergent to flow out of the warehouse and sparking a mop—up of Pang Sua Canal.

PUB said its officers are still clearing up the remaining foam and it is monitoring the water quality closely.

As a precautionary measure, PUB has stopped pumping water from Sungei Pang Sua until the foam is completely cleared.

PUB assured residents that raw water from Singapore’s reservoirs is treated at its waterworks to meet World Health Organisation drinking water quality standards before it is supplied to households.
