PETALING JAYA - When the last rationing exercise was imposed between February and March, the level at the Sungai Selangor dam was 37 per cent. It is now 33.46 per cent.
The state is heading for a water crisis and consumer groups want the Selangor government to disclose its plans to avert that.
Water Forum Malaysia manager Foon Weng Lian said the state was duty-bound to inform consumers of the latest situation.
Fong said the NGO, appointed by the National Water Services Commission (SPAN) to represent consumers in water supply and sewerage services issues, was concerned over the lack of information.
"So far, there have been only rumours and our concern is what information is being withheld," he said.
The dam serves as a reserve for Sungai Selangor, which supplies 60 per cent of the raw water needs of the Klang Valley and Putrajaya.
Apart from the pumping of water from disused mining pools in Bestari Jaya into Sungai Selangor, Fong said that the Selangor government had not disclosed its other measures to mitigate the situation.
Foon urged SPAN not to wait until reserves reached 30 per cent before stepping in.
Environmental Protection Society Malaysia president Nithi Nesadurai, who agreed about the lack of information, said it was clear there would be problems if the current dry spell persisted.
He said the state should have been more proactive and not have waited for the situation to reach this stage.
"They certainly need to be more open and should have engaged consumers, who can be part of the solution," he said.
The plan to bring water in from Pahang is not about to be realised any time soon.
Pahang-Selangor Raw Water Transfer Project director Dr Zullkefle Nordin said the trial project would kick off in November.
"We are currently in the process of dismantling the tunnel boring machinery."
Dr Zullkefle said between now and the time the Langat 2 water treatment project was fully completed, the water from Pahang would be sent to the Batu 11 Cheras and Bukit Tampoi water treatment plants.
Batu 11 can distribute 22 million litres of treated water a day, while Bukit Tampoi can release 34 million litres a day.
A RM5million (S$1.95 million) pipeline to carry 500 million litres per day from the end of the tunnel to Sungai Langat is now being built.
