Selangor outlines measures to overcome water supply disruptions

SHAH ALAM: The Selangor state government has outlined several long- and short-term measures to overcome river pollution problems that have caused water supply disruption to be rampant recently.

Selangor Menteri Besar Datuk Seri Amirudin Shari said the short-term measures include increasing enforcement at the two vital rivers, namely Sungai Langat and Sungai Selangor, that serve as water sources for the state.

Suggestions have been made to the Selangor Water Management Board and Pengurusan Air Selangor Sdn Bhd (Air Selangor) to add around 20 enforcement personnel to patrol both rivers.

“In addition, the state government will also use drone technology to monitor and analyse water quality. The drones will also determine if factories near the rivers are able to contaminate any part of the 1,000km stretch of the rivers,” he told a media conference yesterday.

In the long term, the state government is considering the use of several technologies that can eliminate odour pollution at the river and the water treatment plant (WTP) to avoid a shutdown.

In addition, the state government is also considering building barriers to stop contaminated water from entering the WTP and using the water supply from the Hybrid Off River Augmentation System (HORAS) 600 as a replacement, Amirudin said.

He cautioned that the longterm measures might take some time to achieve as the cost could reach several hundred million ringgits.

While discussions would be held regarding demands by affected consumers asking for a discount for their Air Selangor bills due to the water disruption, Amirudin said that the state government felt that the total bill paid would be better used on enforcement and monitoring of the rivers in the state.
