WATER supply is expected to be restored gradually starting tomorrow if pollutants in Sungai Selangor are cleared by tonight, said Selangor executive councillor Hee Loy Sian 

The Selangor Tourism, Environment, Green Technology and Orang Asli Affairs Committee chairman said the latest Threshold Odour Number (TON) reading at the Rantau Panjang Water Treatment Plant has dropped from 8 TON to 4, while SSP LRAs 1,2 and 3 are still at 4 TON.

“If it recovers tonight, the plants are still unable to treat the raw water even though the reading is at 0 TON because we have to follow some standards set by the Health Ministry,” Hee said.

“The restoration of water supply is expected to (start) tomorrow morning but in stages and it will take about 10 hours from the first area if we resolve this issue tonight,” he said at Volex Park Sewage Treatment Plant (IWK) during a press conference today.

Earlier today the Selangor Water Management Authority (Luas) announced the shutdown of four water treatment plants in the state after odour pollution was detected

The 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.

This is the third large-scale disruption in recent months in the Klang Valley.

Early last month, the Sg Semenyih and Bukit Tampoi water treatment plants were shut down due to river contamination.

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 supply disruption involving the same water treatment plants due to river pollution. – November 10, 2020.
