Groups: Water crisis likely

Various watchdog groups on water have predicted that there will be a danger of water shortage if nothing is done to feed the growing demand for treated water.

Association of Water and Energy Research Malaysia (AWER) is standing by its estimation that Selangor, Kuala Lumpur and Putrajaya would experience a water crisis by 2014 if the Langat 2 treatment plant conti­nues to be delayed and the demand in the state increases between 2 per cent and 2.5 per cent annually.

“Using statistics published by the Malaysia Water Industry Guide 2011, AWER found the average increase of annual treated water production (and hence, demand) in these three areas to be 2.14 per cent,” said president S. Piarapakaran, who first announced the association’s predictions earlier this year.

He added that if this continued for the next few years, it would raise the demand to more than 4,397 million litres per day (MLD) by 2014; which is above 99 per cent of the projected ma­­ximum supply capacity (4,431 MLD) of the to-be-upgraded treatment plants and the recently completed Sg Labu treatment plant.

“We need a 1 per cent reserve margin to allow for leakages and ensure that the water pressure within the pipes is maintained at a level that prevents untreated water from outside the pipes from flowing in,” said Piara­pakaran, adding that a safe level of water reserve margin was about 20 per cent.

The current water production reserve margin, according to the National Water Services Commis­sion (SPAN), is less than 1 per cent.

The Water Association of Sela­-ngor, Kuala Lumpur and Putrajaya (SWAn), on the other hand, is very worried with reports that the current hot weather has increased water de­mand in the Klang Valley beyond the maximum production capacity of the water treatment plants that supply the area.

In a press statement released last week, SWAn said according to Syarikat Bekalan Air Selangor (Syabas) data, the average water demand in the three areas had risen to 4,329 MLD, compared with the maximum operating and distributable capacity of the water treatment plants of 4,371 MLD (including the newly commissioned Sg Labu Water Treatment Plant).

Meanwhile, at a recent conference organised by the Selangor Go­­vernment, Coalition for Sustainable Water Management chairman Dr Lee Jin claimed that the Federal Go­­vernment’s projections based on the National Water Resource Study (NWRS) 2000 was flawed as it over-estimated the increase in demand in the state.

Citing the latest (unpublished) NRWS 2011, Dr Lee said the graph of water consumption in the state had actually flattened.
