PETALING JAYA: Syarikat Bekalan Air Selangor (Syabas) again closed the Sungai Semenyih Water Treatment Plant on Friday afternoon.
The plant ceased operations at 4:15pm when the bund at Sungai Buah in Nilai, Negri Sembilan, the source of the contamination earlier in the week, gave way following a heavy downpour upstream.
The bund had been erected to prevent the poisonous water from flowing into Sungai Semenyih and diverted to a nearby pond.
(The plant, which shut down on Sunday, resumed its operations on Wednesday and supply was expected to resume fully to over a million customers by Saturday.)
“Every effort is being taken to restore the bunds at Sungai Buah immediately and prevent the polluted water from flowing into Sungai Semenyih,” said Syabas Corporate Communications head Amin Lin Abdullah said in a statement Friday.
Amin said all areas in Hulu Langat, Kuala Langat, Sepang and Petaling Districts will experience temporary water disruption until the water treatment plant resumes operations.
He said relief water supply would continue to be sent by water tankers to affected areas and critical premises, namely hospitals and dialysis centres, until water supply is restored.
It also said that the existing water schedule for Zones 1 and 2 is no longer valid.

The Sungai Semenyih Water Treatment Plant was forced to close temporarily on several occasions since September following contamination at Sungai Semenyih.
Sources of pollution had been identified to come from an industrial site in Semenyih, including Sungai Langat, which gets water from Pahang.
The closures caused water disruptions that have affected over a million residents in the Klang Valley.
