KUALA LUMPUR: Indah Water Konsortium Sdn Bhd (IWK) says the closure of the Sungai Semenyih water treatment plant on Saturday (Sept 28) was not caused by its sewage treatment operation.

It said that the incident was caused by illegal discharge of chemical waste near the sewage plant at Bandar Bukit Mahkota.

“The IWK, together with the Department of Environment (DOE), had lodged a police report about the matter.

“Police arrived at 10pm yesterday to inspect a manhole suspected of being the discharge point of the contaminant," it said in a statement Sunday (Sept 29).

It added that all maintenance works were carried out in accordance with the specifications and procedures stipulated by the authorities.

Meanwhile, water supply to 47% of consumer accounts in the Klang Valley resumed as of noon Sunday after the Sungai Semenyih water treatment plant resumed operations.

A total of 372,031 consumers in the Petaling district, Hulu Langat, Kuala Langat and Sepang experienced unscheduled water cuts due to odour pollution at the Sungai Semenyih raw water sources on Saturday.

Pengurusan Air Selangor Sdn Bhd (Air Selangor) said water tankers had been mobilised and 10 local service centres were activated at 8am to assist customers until the water supply was fully restored.

Air Selangor had said that the source of contamination was traced to a sewage treatment facility in Bandar Bukit Mahkota.

Selangor Environment, Green Technology and Consumer Affairs Committee chairman Hee Loy Sian, in a statement Sunday, said an investigation was initiated by Selangor Water Management Authority (LUAS) and the DOE.

The investigation revealed that a manhole in Bandar Bukit Mahkota might have been used to discharge contaminants before it entered the sewage treatment plant in Bandar Bukit Mahkota.

“LUAS received a report from Air Selangor regarding a solvent smell detected 1.5km away from the Sungai Semenyih water treatment plant at 2.31pm yesterday.

“As a result, the Sungai Semenyih water treatment plant was shut down at 5pm to conduct water sampling,” it said.

It added that IWK had stopped effluent flow into their treatment plant at 8.15pm Saturday and chemical treatment was then initiated at 10.45pm.

"The aerator tank was dosed with 575kg of activated carbon at 3am today. The heavy rain had also helped to reduce the solvent smell," it added.
