SHAH ALAM: The Sungai Langat and Cheras water treatment plants resumed operations at 9am and noon respectively today.
Tourism, Environment, Green Technology and Consumer Affairs executive councillor Elizabeth Wong said water supply to affected areas in Kuala Lumpur, Petaling Jaya and Hulu Langat will be gradually restored – until then, relief water supply will be distributed based on a schedule as a stop-gap measure.
Wong said Air Selangor’s River Surveillance team is still in Pahang to assist the Pahang Water Resource Authority and Pahang Department of Environment in identifying the source of last night’s odour pollution in Sungai Semantan.
The two water treatment plants had to be temporarily shut down at 8.30pm and 10pm respectively due to odour pollution suspected to have originated from the Semantan river in Pahang.
Both plants, which receive raw water supply from the Semantan river, have switched to the Sungai Langat dam as their new source of water, said Air Selangor Group corporate communications head Amin Lin Abdullah.
Amin said relief water supply distribution to areas experiencing water disruption will begin tomorrow.
"(This) is to ensure that consumers do not experience interruption for an extended period.
"Relief water supply will be delivered by tankers to affected areas and critical public facilities, such as hospital and dialysis centres.
"Consumers are urged to use water supply prudently during this restoration period,” he added.
Amin had earlier said water from the Sungai Langat dam had been released into the river at 9.45pm last night as part of efforts to mitigate the odour pollution.
The shutdown had resulted in taps in several areas in Kuala Lumpur, parts of Petaling Jaya and Hulu Langat running dry.
