River water bad, dam water dropping

Going with the flow: Air Selangor workers using excavators to block the flow of water from the contaminated Sg Buah into Sg Semenyih.

PETALING JAYA: While the authorities are grappling to contain the contamination that has shut down water treatment plants three times this month, they also have another problem on their hands.

The water level at the Sungai Selangor dam that supplies 60% of Selangor and Putrajaya’s treated water is dropping fast and is now close to the 40% level which triggered water rationing two years ago.
