THE water rationing exercise in the Klang Valley was recently extended to the end of the month. Apparently, the earlier exercise only yielded seven per cent savings. This was not surprising as the ration was not specifically done "over volume" but "over time" ( two days on, two days off).
During days when there was supply, consumers would usually stock up to face the imminent disruption. It is also possible, on days when there was supply, consumption could have been close to double (or more) than what was normal
