SOME 463 areas in the Klang Valley will be facing water supply cuts after odour pollution was detected in Sg Semenyih.

The supply disruption to the affected areas comes only two days after supply was restored to affected areas.

Air Selangor announced on its Twitter account that the Sg Semenyih water treatment plant had to be completely shut down at 5.15 pm today due to odour pollution.

According to its tweets, areas in Petaling, Hulu Langat, Sepang, Putrajaya and Kuala Langat are affected with water disruption.

Consumers can get the list of areas affected through the Air Selangor website well as the Air Selangor mobile app.

The 463 areas in the Klang Valley that faced a disruption from Tuesday onwards had their supply restored only yesterday.

In November last year, four water treatment plants in Selangor were shut down due to odour pollution.

That disruption affected 1.14 million account holders in 1,279 areas across Kuala Lumpur, Petaling, Klang, Shah Alam, Kuala Selangor, Hulu Selangor, Gombak and Kuala Langat.

Later the same month, Sg Selangor water treatment plants 1, 2 and 3, and the Rantau Panjang plant were also closed after pollution was detected in the river.

September also saw six days of disruption involving the same water treatment plants due to river pollution. – September 3, 2021.
