WATER supply to affected households in several districts in Selangor will resume in stages over the next three days starting midnight yesterday.
Pengurusan Air Selangor Sdn Bhd (Air Selangor) CEO Suhaimi Kamaralzaman said in a statement yesterday that the resumption will be spaced out into three main stages.
“The first stage will see supply restored to 145 areas by 6pm on Wednesday, while another 91 areas in the second stage will have their supply restored completely by 6pm on Oct 8.
“The third stage will involve 38 areas that will receive supply by 6pm on Oct 9,” he said.
According to Suhaimi, the Sungai Semenyih water treatment plant (LRA) had resumed operations yesterday morning.
Earlier, Air Selangor said sampling tests carried out at the Sungai Semenyih LRA came out with readings of zero TON (threshold odour number) three times consecutively.
However, a pollution of Level 2 TON was still detected at the Bukit Tampoi LRA from a sampling test conducted until 6am yesterday.
The water provider noted that the Sungai Semenyih LRA had begun pumping raw water yesterday morning for the cleaning of the pipes and treatment tanks.
“Efforts to treat raw water and stabilise the LRA system will take 12 hours before water supply can be distributed to consumers.
“The water supply will go through quality testing and standard compliance by the Health Ministry,” it said in a statement.
The schedule for water supply restoration will be informed in stages once the process of water stabilisation treatment can be implemented fully.
“Air Selangor has mobilised 92 water tanker trucks to critical premises, schools and affected residential areas, while 22 static tanks, 10 local charging stations, nine local service centres and 13 public taps are provided for the convenience of the affected users,” it said.
The unscheduled water supply disruption has affected 309,687 households in four districts, namely Petaling, Hulu Langat, Kuala Langat and Sepang caused by raw water pollution.
Due to the pollution, both Sungai Semenyih and Bukit Tampoi LRAs have halted work on Sunday.
Air Selangor said it will also update information on unscheduled water supply disruption from time to time through all Air Selangor communications and social media platforms, including Twitter, Facebook, Instagram and its website www.airselangor.com.
