Selangor executive councillor Hee Loy Sian is unhappy that Indah Water Konsortium (IWK) Sdn Bhd failed to notify the Selangor state government that a premises at Taman Velox in Rawang was suspected of illegally disposing chemical waste into a toilet one week ago.

The incident later led to a water supply disruption affecting over one million consumers in the Klang Valley.

At the Selangor State Legislative Assembly sitting in Shah Alam today, Hee expressed his disappointment, saying that appropriate action could have been taken if the state government was promptly informed.

He said IWK had suspected the operator of the premises of dumping scheduled waste, which caused IWK's plant to receive a reddish substance forcing it to suspend its operations on Nov 4.

He said IWK only notified the National Water Services Commission (Span) of the situation and not the state government.

The incident later led to the pollution in Sungai Selangor and resulted in the closure of four water treatment plants in Kuala Selangor yesterday.

“IWK also lodged a police report on the matter while Span decided to remove the waste manually to another location, using lorries, and shut down the plant.

“Luas and Pengurusan Air Selangor Sdn Bhd (Air Selangor) were not informed about this and if we had known, we could have taken appropriate action sooner,” Hee was quoted as saying by Bernama.

Hee explained that the incident was the fourth brought up by IWK this year and they should have been more responsible in managing their sewage treatment plants.

“This is the fourth time it has occurred... twice in Bukit Mahkota, Semenyih, once in Batang Kali, Hulu Selangor, and now in Rawang,” he said.

According to him, the state government had lodged a police report on the incident and would bring anyone involved in causing water pollution in the state to justice in accordance with the Luas Enactment 1999.

Yesterday, Air Selangor announced that operations at the Rantau Panjang and Sungai Selangor Phase (SSP) 1, 2 and 3 water treatment plants had to be suspended due to pollution of raw water sources.

This disruption affected 1,139,008 premises in Kuala Lumpur, Petaling, Klang, Shah Alam, Kuala Selangor, Gombak and Kuala Langat.

Secretary-general of the Ministry of Environment and Water, Zaini Ujang, was reported as saying that the water pollutant was believed to have come from the small and medium industry area in Taman Velox, Rawang.
