SHAH ALAM, Feb 21 — The Selangor Water Management Authority (Luas) regularly monitors the Hybrid Off River Augmentation Storage (Horas) 600 system, to ensure the quantity and quality of raw water supply can be maintained.
The agency also monitors and checks for other alternative water sources, and ensure they can be used whenever the need may arise.
“Horas 600 is one of the components of the Raw Water Security Scheme (SJAM) by the state government. The alternative raw water from Horas 600 will be diverted into Sungai Selangor, to increase the river flow level and reduce the release of water from the dams at Sungai Selangor and Sungai Tinggi.
“The system is also capable of providing an alternative supply of raw water for an estimated 100 days during the dry season, while simultaneously able to increase the dilution rate in river water in the event of raw water quality (pollution) issues,” it said in a Facebook post.
Previously, during the tabling of the 2021 Selangor Budget, Menteri Besar Dato’ Seri Amirudin Shari outlined four steps to overcome water supply disruptions.
They include a nanotechnology treatment pilot project to treat Sungai Gong water, and increase the number of water quality telemetry stations for the early warning system situated upstream of the intakes.
The other steps are the implementation of a raw water pumping project from the Horas reservoir and the off-river storage (ORS) in Bestari Jaya, as well as 24-hour monitoring and surveillance in sensitive areas.
