The Rantau Pantang water treatment plant has resumed operations today after being shut for about two-and-half hours due to odour pollution.

This came just a week after the same plant and three others reopening following an allegedly illegal discharge of chemical waste.

“Investigations are still ongoing regarding the odour pollution reported earlier. At the same time, the Rantau Panjang water treatment plant has resumed operations at 9.30pm after a reading of zero threshold odour number (TON) was recorded,” the Selangor Water Management Board (Luas) said on Facebook today.

Earlier, Luas announced that Air Selangor had detected a solvent-like odour at the treatment plant’s inlets at 7pm today, with a TON reading of one.

“Following this, the Rantau Panjang water treatment plant has ceased operations at 7.10pm.

“Luas, Air Selangor and relevant parties are conducting investigations and immediate mitigation actions. Any developments will be informed from time-to-time,” it said.

The same plant was among the four shut down last week after a factory is believed to have dumped chemical waste that eventually ended up in state’s rivers.

It had resumed operations on Nov 11 once the pollution has been cleared.
