BESTARI JAYA, 15 Mar: To increase the supply of raw water to the consumers in the Klang Valley, the State Government is now working on implementing the Hybrid Off-River Augmentation System (HORAS) which is expected to be completed in July 2015.
The Chief Minister, Tan Sri Abdul Khalid Ibrahim, said that the project which will be built on a former tin mining area of 235 hectares at Kampung Sungai Darah will be capable of supplying 600 to 700 million litres per day (MDL) of clean water.
He said that the Phase 1 reservoir will be pumped to the water treatment plant nearby; the SSP1, which is located about three kilometres away.
“Horas is a combination of the off-river storage concept and the horizontal collector well which involves the accumulation of stormwater from Sungai Selangor (excess water from the use of existing plants and rainwater) and groundwater collection,” he told reporters after inaugurating the ground-breaking ceremony here at the Horas project site.
Abdul Khalid said that for Phase 2, the Horas project is expected to accommodate 3,000 to 5,000 MLD by 2020.
“The HORAS concept is beneficial by reducing absolute reliance on the release of dam water and surface water and it is able to meet demands during a drought.
“In addition, it will avoid wastage of rain water with the sustainable management of water resources and to prevent the risk on downstream settlements,” he said.
The project covers bank protection works using Reno Mattress with an area of approximately 1,930 metres.
It also involved reparation and preservation of the 3.8 kilometre river; which is to widen and deepen the Sungai Selangor.
In addition, it covers the installation of sheet piles along three kilometres to prevent river water from seeping into the reservoir and to protect banks from erosion, the raw water pumping station and access roads, as well as landscaping.
Abdul Khalid said that the project will reduce the excessive dependence of raw water to one raw water source, thus assuring continuous water supply to over seven million consumers in the Klang Valley.
“With the completion of this project, apart from assuring continuous water, it is expected to become a new attraction for Kuala Selangor,” he said.
