In a statement, Air Selangor corporate communications head Elina Baseri said water supply in all 463 affected areas is expected to fully recover before Friday.

She said Air Selangor has also conducted water quality testing and it complied with the standards set by the health ministry.

“The treated water from the Sungai Semenyih water treatment plant has also been certified safe for distribution to consumers by Suruhanjaya Perkhidmatan Air Negara (SPAN),” she said.

Elina added that Air Selangor would continue to mobilise alternative water supply assistance to the affected consumers and critical premises.

“A total of 94 water tankers have been mobilised to the affected consumer areas during this unscheduled water supply disruption.

“Air Selangor is seeking consumers’ cooperation to practice social distancing and wear face masks while collecting water from the water tankers,” she said.

Yesterday, the Sungai Semenyih water treatment plant was shut down at 11.10am after odour pollution was detected at the Jenderam Hilir raw water pump station.

However, last night, Air Selangor said there was no more odour pollution detected at the Sungai Semenyih water treatment plant but it will take around 36 hours before supply in the affected areas resumes.

Some 172 areas in Petaling, 194 in Sepang, 54 in Hulu Langat, 23 in Putrajaya and 20 in Kuala Langat were affected by the water disruption on Merdeka Day.

Among the areas affected include Serdang Hospital and Universiti Putra Malaysia Hospital (HUPM) as well as the Malaysia Agro Exposition Park Serdang (MAEPS) low-risk quarantine and treatment centre.
