JOHOR BAHRU: About 17,000 account holders under the Ranhill SAJ water company in Kulai faced water supply disruption which began on Wednesday morning due to ammonia contamination at Sungai Sayong.
Johor International Trade, Investment and Utility Committee chairman Jimmy Puah said the pollution occurred as a reservoir at a bio-composite centre next to an oil palm mill in Sedenak broke, causing water containing ammonia to flow into Sungai Sayong.
“The contamination caused the Sayong 1 and Sayong 2 water treatment plants to be closed at 6.30pm on April 3 because the water could not be treated due to high ammonia content.
“At 5.30am and 11.30am, operations at the Semanggar and Sg Johor water treatment plants were also halted due to the contamination, before the one in Tai Hong was closed at 1.30pm,” he said in a statement here yesterday.
Puah said the water supply was expected to return by 10pm.
“The authorities have taken action against the premises by cancelling the raw water abstraction licence with immediate effect, and will impose a compound based on the severity of the incident.
“The Johor government will not compromise with irresponsible parties,” he added.
