From my Facebook friend and 'mentor' Uncle Fuad Omar ;
"Water Management is just like economics....Supply, Demand & whats in your pocket.....how can you say what is your pocket is OK without addressing the supply (hydrology) and demand (water demand ..present & projected).....
What Khalid has implied with 55% capacity of the dam......he is 100% sure the supply and demand is OK...this is wrong...unless the dam is 100% capacity at 100% of the time and he can safely say that the supply and demand is 100% OK....tu pun kena qualify for how long since supply is fixed & demand has projection i.e selalunya ikut GDP.
And this what Langat 2 & Pahang Water Transfer is all about.....i.e
1 - The treatment plant capacity need to upgraded (new or rehab) to meet the demand since the demand moving target base on projection
2 - Raw water supply is almost assured (i.e almost 100% at all time).....since supply (hydrology) is fixed....hence has to be import from somewhere to be consistent with the demand."
Hopefully , Pakatan leaders especially Khalid Ibrahim smart enough to digest the above information , though the above quote mentioned about "economic" , please please please don't try to get the Selangor's economy advisor to explain or else, rest of the world will make jokes on us.
