SHAH ALAM, Dec 24 — The water supply in areas affected by the odour pollution incident is gradually returning, following the resumption of operations of the Sungai Semenyih treatment plant at 1pm yesterday, says Pengurusan Air Selangor Sdn Bhd (Air Selangor).
In a statement today, the Health Ministry and the National Water Services Commission (SPAN) have been monitoring and carried out regular water quality tests at the treatment plant to ensure that the treated water meets the required standards for distribution.
“The treated water supply has begun to flow into the distribution system to be supplied to the customer’s premises, starting at 1am. Some of the affected areas have started receiving water earlier this morning.
“Air Selangor is currently in the process of stabilising pressure of the main pipeline and the main pools.
“The recovery of water supply will take place in stages, depending on the geographical location and altitude of the customer’s premises,” said Air Selangor corporate communications head Abdul Halem Mat Som in the statement.
He said the expected full recovery time of the water supply is would be within 72 hours and consumers will be updated on the list of restored areas from time to time.
Meanwhile, he said the Bukit Tampoi treatment plant remains closed as the odour pollution is still detected.
“Emergency assistance through water tank trucks will continue to be sent to the affected areas,” he said.
The public is urged to refer to the Air Selangor app, Facebook and Instagram or its website www.airselangor.com for information or updates.
Consumers can also contact Air Selangor at the 15300 phone line or WhatsApp to 019-2800919/019-2816793 for assistance.
Yesterday, Selangor Menteri Besar Dato’ Seri Amirudin Shari said authorities have detected the source of the pollution, caused by solvent and black oil, to have originated from an Indah Water Konsortium manhole at Bandar Bukit Anggota in Bangi.
The incident had affected 336,930 consumer accounts in Petaling, Hulu Langat, Kuala Langat and Sepang.
SPAN had on Sunday lodged a police report on the odour pollution incident, which resulted in the forced closing of Sungai Semenyih and Bukit Tampoi Water treatment plants.
Its chairman Charles Santiago said allegations of the possibility of elements of sabotage coming into play had cropped up as such pollution incident had occurred three times in Selangor, where two cases involved the same location.
