WATER supply to consumers affected by a shutdown of the Sg Semenyih water treatment plant will resume in stages tonight, said Pengurusan Air Selangor Sdn Bhd (Air Selangor).

However, Air Selangor chief executive Suhaimi Kamaralzaman said the Bukit Tampoi treatment plant will remain shut.

“As of 3pm today the level of pollution at the Sg Semenyih plant read 0 TON three times in a row but Bukit Tampoi still detects pollution with three TON,” said Suhaimi.

“The 15,000 accounts of Bukit Tampoi water treatment plant recipients will get their water supply from the Sg Semeyih plant instead for now,” he said at a press conference today.

He said supply resumption has been divided into three groups, with consumers living nearest to the plant receiving supply first.

“The first group will receive full water supply by 6pm, October 7 whereas the second group will receive full water supply at 6pm, October 8, and the third group will receive full water supply by 6pm, October 9 ,” he said.

Suhaimi added that the first group consists of 145 areas, the second group consists of 91 areas and the third group consists of 38 areas.

The plants were shut on Sunday after pollution was detected in the water source.

The plants’ failure to produce the daily 600 million litres of water has left more than 300,000 consumers high and dry in Petaling, Hulu Langat, Kuala Langat and Sepang.

The shutdown comes less than a month after another case of river pollution left 1.2 million consumers in the Klang Valley without clean water supply for six days.

The Sg Selangor Phase, 1, 2 and 3 and the Rantau Panjang water treatment plants shut down after a factory was suspected of dumping waste into Sg Gong, which feeds Sg Selangor.

Four brothers were charged with polluting the river. – October 6, 2020.
