KUALA LUMPUR: Pengurusan Air Selangor (Air Selangor) is now preparing for the treatment process to commence in Sungai Semenyih Water Treatment Plant (LRA) so that safe and clean treated water can be distributed to consumers.

Air Selangor Corporate Communication chief Elina Baseri said the move was taken after zero TON (threshold odour number) level readings were recorded three times consecutively in Sungai Semenyih at 6 am today.

She said 463 areas in five Air Selangor regions experienced unscheduled water supply disruptions following the shut down of the Sungai Semenyih LRA yesterday.

The five regions were Petaling (172 areas), Hulu Langat (54), Sepang (194), Putrajaya (23) and Kuala Langat (20).

"A total of 94 tanker lorries have been mobilised to the affected areas and critical premises during the supply disruption.

"Air Selangor is taking all measures to minimise the impact of the disruption on consumers," she said in a statement today, adding that developments on the disruption would be announced from time to time through all mediums especially the mass media.
