【明報專訊】IN the next three years, the cost of Dongjiang water will continue to go up $200 million a year. The government has said it has no plan to raise water charges. Therefore, though Dongjiang water will cost Hong Kong more, citizens will not be charged more. On the face of it, the government is solicitous of citizens. However, as the money paid to the Guangdong authorities comes from the public purse, it is the taxpayer that will bear the cost. Because the central government looks after Hong Kong, we have no lack of water, and water is cheap here. Therefore, Hong Kong people tend to use a lot of water, and some even waste it. This is a big concern.
