OPERATIONS at the Sg Semenyih and Bukit Tampoi water treatment plants have resumed as of 3.30pm, with affected households being able to receive their water supply by tonight, Selangor Menteri Besar Amirudin Shahri said.

This is after taps had run dry in 472 areas in the Klang Valley following odour pollution detected at the Jenderam Hilir raw water pump station intake.

Amirudin said the issue of pollution had been sorted.

“This came after three readings of 0 TON (Threshold Value Odour Number) was recorded and the pollution was successfully resolved,” he tweeted.He said that water supply was expected to be channeled in stages starting tonight.

According to him, this was the third incident of pollution in the same place this week.

The Malaysian Insight has reached out to Air Selangor and Lembaga Urus Air Selangor (Luas) and is awaiting a response to find out whether these incidents are an act of sabotage.

Earlier today Air Selangor announced that operations at the Sg Semenyih and Bukit Tampoi water treatment plants had been temporarily halted due to odour pollution.

Five localities, Petaling (172 areas), Hulu Langat (54), Sepang (196), Putrajaya (23) and Kuala Langat (27) experienced unscheduled water supply disruptions starting 3pm.

Consumers were very unhappy when they were notified about the water disruption during the Hari Raya festive period.

Cindy Wong commented on Air Selangor Facebook post that she would rather move to a place that does not use Sg Semenyih for water supply.

Another consumer Shahrul Azmi said those Air Selangor employees who went on leave should return to work, as it’s a crucial time referring to Hari Raya Aidilfitri.

Consumer Muhd Hafiz was annoyed that pollution in water treatment plants takes place almost every week and yet there’s no solution to it. – May 3, 2022.
