SHAH ALAM: A total of 512 areas involving 377,141 registered consumers from 4 districts - Petaling, Hulu Langat, Kuala Langat and Sepang - will be affected, in stages, by supply interruption and low pressure.
This was due to the total shut down of the Sungai Semenyih Water Treatment Plant (WTP) at 5pm on Wednesday after odour pollution was detected in Sungai Semenyih.
The river is the source of raw water for the WTP.
Pengurusan Air Selangor Sdn Bhd customer relationship and communication department head Abdul Raof Ahmad said the source of pollution, at a distance of 16 kilometers from the WTP’s intake, has been identified.
“The Selangor government’s enforcement agency took immediate action to stop the flow of pollution to the river.
“Based on the odour, its strength and the flow into the river, we expect the WTP to only resume operations within 15 hours at 11am tomorrow (Thursday, June 27). The situation is also subjected to weather conditions and river current should there be no further pollution threat.
“The plant will take three hours to resume operations optimally which include the pumping of raw water and processing it into treated water for distribution to the balancing reservoirs.
“Restoration will be in stages, depending on the location and altitude of the areas. We are aiming for full recovery for all affected areas within 72 hours after the WTP is fully operational,” said Abdul Raof in a statement.
He added that the Emergency Response Plan (ERP) Code Yellow was activated at 8pm to coordinate emergency water supply assistance to affected customers.
Abdul Raof added that they will mobilise all existing assets as well as support assets from local authorities and other agencies.
The Local Service Centres (LCS) which will be activated and its locations will be announced soon.
He said they will channel assistance and minimise the impact of supply interruption to consumers.
