If you follow PUSPEL on Twitter, you will realise how precarious the water supply situation in the Klang Valley is. Treated water is supplied at 4,371 MLD (million liters per day) in the Klang Valley, while the optimal reserve capacity should be between 15 to 20 percent that amount.
However, between 5th June to 11th June, the buffer was only between 1 to 2 percent. On 5th June, it was at 2.06 percent while on 7th June, it was at 1.22 percent. On 17th June, the demand for treated water exceeded supply at 4,410 MLD. This shows that there was a deficit of treated water. Because of this, the Minister for Energy, Green Technology and Water, Datuk Seri Peter Chin was reported to have said to reporters that “the danger zone is so near that we may resort to rationing water.”
While the effort to reduce non-revenue water (NRW) is ongoing, it would be more expensive as a short term goal to reduce NRW than it is to build treatment plants. The government would have to spend RM7.2 billion to reduce the NRW from 32.3 percent this year to 20.83 percent in 2020, and this would only save 126 MLD annually, while the Selangor-Pahang water channeling scheme, which involves building of the Langat 2 water treatment plant, would cost RM5 billion, but provide consumers in the Klang Valley a further 1,130 MLD. Of course, there is a need to educate the consumers in the Klang Valley the importance to conserve treated water. On average, Malaysians use 200 liters of treated water per person per day, while those in Selangor use 239 liters per person per day. To make matters worse, demand increases by 7 percent during the hot season such as now. In my opinion, the state government should increase tariff and not give free/subsidised water to consumers. This would help educate consumers to value water instead of looking at it as God’s eternally endless gift to mankind.
And with the bravado shown by the Selangor state government, we in the Klang Valley will soon be able to enjoy daily supply of ikan kering in lieu of water from the water catchment areas.
