SINGAPORE - Residents staying in Punggol have complained of brown-coloured tap water from their residential units on Thursday.
The Public Utilities Board (PUB) was alerted to the complaints at 2pm. A PUB spokesperson told AsiaOne that around 50 blocks in Punggol were affected, although not all residential units experienced the discolouration of tap water.
PUB said on its Facebook page at 7pm that it carried out valve works on a water main along TPE around noon to prepare for the connection of a newly laid pipeline.
Despite flushing the pipeline before the valve works, more sediments in the pipeline were dislodged and resuspended, resulting in the discolouration of the water.
Residential units on the lower floors tend to draw their water supply from the water mains, while residential units on the upper floors draw from water tanks on the roof top.
"These sediments are minerals in tap water which settled down over time in the pipes," PUB said.
It assured the public that the water will clear after flushing, and that its officers are on-site to flush the PUB mains and assist affected customers with the flushing of their service pipes.
Temporary water supply has also been deployed to affected customers.
For feedback, members of the public can contact PUB's 24-hour call centre at 1800-284-6600.
