River pollution caused water treatment plants in Selangor to shut down 42 times last year, disrupting supply to thousands of consumers for 2,838 hours, The Star reported today.
Citing the state’s main water concessionaire, Syarikat Bekalan Air Selangor (Syabas), the report said the plants in Sungai Semenyih and Bukit Tampoi had already been shut down six times so far this year.
The most recent was in April when pollution of ammonia and manganese in Sg Semenyih caused the plant’s closure. And, supply to 395,427 households in the Petaling, Hulu Langat, Kuala Langat and Sepang districts was cut without notice.
Luas director Md Khairi Selamat said the system, based on data from water intake points, river flow and land use, acted as an early warning to identify potential locations for pollution at all water catchment areas in the state.
“Based on our checks, the place with the most potential for pollution is Sg Sembah near Rawang which has an increasing number of residential and industrial areas,” The Star reported him as saying.
Sg Sembah is one of the tributaries and a sub-catchment area for Sg Selangor, which currently supplies over 60% of raw water in the state.
Md Khairi said any closure of treatment plants would have to be streamlined by Luas via the state’s emergency committee on water sources pollution. – May 11, 2015.
