JOHOR BARU: Around 1.8 million residents in Johor Baru have been affected by a major water supply disruption, after operations at three water treatment plants were stopped due to high ammonia levels found in their raw water from the Johor River, local media reported on Saturday (Oct 28).

Operations were halted at the Semangar, Johor River and Tai Hong plants on Saturday, the Star Online reported.

Residents in three districts - Johor Baru, Kulai and Kota Tinggi - have been affected and the shutdown may last for up to two days, it added.

Jamaluddin Jamal, head of corporate communications at water supply company SAJ Ranhill Sdn Bhd, told the Star Online that ammonia levels of 2.75 parts per million were recorded in the raw water on Friday night and that levels had not gone down as of Saturday afternoon.

The permitted ammonia level is 1.5 parts per million according to the Star Online.

"Water quality is our priority, thus we decided to halt operations to treat raw water from the river," he told the Star Online. "This is not the first time high levels of ammonia have disrupted water supply. We have recorded three major incidents this year alone."
