[ UPDATE 31/8/2021 20:54 ]: Air Selangor has updated that the Sungai Semenyih Water Treatment Plant can resume operations after getting three 0 TON (threshold odour number) readings at Sungai Semenyih. However, a cleaning process has to be completed first before water can be treated and distributed to users. This would take approximately 14 hours.
To mitigate water supply issues, they have allocated alternative water supply from LRA Langat 2 and LRA Labohan Dagang to selected areas in Hulu Langat and Kuala Langat. Users in Kajang Baru, Kajang, Semenyih and Beranang in Hulu Langat, as well as Jenjarom, Teluk Panglima Garang and Pulau Carey in Kuala Langat will received alternative water supply periodically.
A total of 94 water tank trucks have been deployed to affected areas. Air Selangor has provided a list of areas that are affected by the water disruption here.

Air Selangor has announced an unscheduled water supply disruption at 463 locations in the Klang Valley. The Sungai Semenyih Water Treatment Plant (LRA Sg Semenyih) was shut down after odour pollution was detected at Jenderam Hilir Raw Water Pump Station at 11.10am this morning.
Air Selangor and Lembaga Urus Air Selangor (LUAS) are currently working together to identify the source of the raw water pollution along Sungai Semenyih and its tributaries.
As a result of the treatment plant shutdown, residents in 463 areas which include Petaling (172 areas), Hulu Langat (54 areas), Sepang (194 areas), Putrajaya (23 areas) and Kuala Langat (20 areas) are expected to face water disruption. According to the statement, the water works company has activated its Emergency Response Plan (ERP) to provide emergency water supply assistance to the affected consumers.
So far Air Selangor has not provided a detailed breakdown of the affected location and estimated time of water supply restoration. Air Selangor is expected to provide more updates through its official social channels including Facebook and Twitter.
The last major Klang Valley water disruption due to a contamination-related incident happened sometime in December last year which affected over 1,200 areas. The time required to restore the full water supply will depend on how soon the water treatment plants can resume operations.
