SHAH ALAM: Raw water from Sungai Semantan in Pahang to Sungai Langat in Selangor was channelled for the first time on Monday to boost its declining capacity.
State Infrastructure and Public Utilities, Agriculture Modernisation and Agro-based Industry Committee chairman Zaidy Abdul Talib said it was done after the Selangor and Pahang governments agreed on the channelling of 500 million litres of water a day (LPD) through the Pahang-Selangor Raw Water Transfer Project (PAMPS).
“The water from Sungai Semantan was pumped at 10.16pm (August 24) when the capacity of the Sungai Langat Dam dropped to 44.24%.
“A total of 300 litres per day was pumped for the first channelling process and flowed into Sungai Langat via a tunnel at 8.30am yesterday,” he said in a statement, here, today.
PAMPS is a project encompassing the transfer of 1,890 litres per day of raw water from Sungai Semantan in Pahang via a 44km tunnel to the Langat 2 Water Treatment Plant (Langat 2) in Selangor.
However, the construction of Langat 2 is only expected to be fully completed in 2019.
“The early channelling of water was a mitigative move aimed at reducing the release of water from the Sungai Langat Dam which is now at 45.07% capacity. With the channelling, the release of water from the Langat Dam and the pumping of water from the Semenyih Dam had been stopped.
“It was also a move to tackle the water supply disruption problem due to the stoppage of the main water treatment plants along Sungai Langat, namely, at Cheras, Batu 11 and Bukit Tampoi during the drought due to the lack of volume and increase of the ammonia parameter in the river,” he said.
In addition, he said, it was to tackle the issue of the drop in water level in Sungai Langat which impacted the water treatment plants, whereby pumping could not be done due to the low water level in the river.
He said the charge of RM50,000 or RM0.10 for every cubic metre of raw water channelled would be paid by the Selangor government to the Pahang government as per the agreement signed.
