Nearly 800,000 in Johor hit by water cuts due to Johor River pollution

It added that areas affected by the disruption include Tiram, Tebrau, Kempas, Iskandar Puteri and Bukit Indah.

Ranhill SAJ also noted that the Semangar water treatment plant, which was among those affected, is expected to gradually reach full operational capacity on Nov 1, while the Linggiu plant has resumed full operations.

“The raw water quality in Sungai Johor continues to be closely monitored to ensure all LRAs can operate at optimum levels,” it said.

The water operator also urged the public to obtain updates on the matter through its official complaint channel at 1-800-88-7474.

It was earlier reported that the turbidity level of raw water in Sungai Johor had surged significantly following the bursting of the sixth washing pond at an inland sand mining site in Kota Tinggi.

Johor works, transport, infrastructure and communications committee chairman Fazli Salleh said monitoring by the Johor Water Regulatory Body, the Irrigation and Drainage Department, the Environment Department, the National Water Services Commission and Ranhill SAJ found that water turbidity had spiked to 37,400 nephelometric turbidity units (NTU), compared with the normal level of around 400 NTU.

“The incident was caused by land-based sand mining activities carried out by a local company when its sixth sand washing pond burst due to soil movement.

“As an immediate measure, water release from the Linggiu Dam has been increased to dilute the contamination in the Johor River,” he said.

The incident affected operations at several water treatment plants, including Linggiu, Semangar, Sungai Johor and PUB (Singapore), potentially disrupting water supply in parts of Kota Tinggi, Johor Baru, Pontian and Kulai.

“The affected areas include parts of Senai, Skudai, Seelong, Felda Linggiu, Petri Jaya and Lima Kedai,” he added. THE STAR/ASIA NEWS NETWORK
