Water saving should never be a short-term measure but be practised constantly. It would be pointless if we people in Macau know the importance of water saving only when we face the real threat of another salt tide.
It takes a long time of education, maybe 10 to 20 years, to cultivate a culture to value water as a scarce resource. But scarcity of fresh water is a global problem so imminent that deprives us of the time.
It is moral as well as practically necessary for Macau to use water wisely, as supplying water to Macau costs the mainland huge amount of resources such as its power generating capacity. Therefore, while education to promote wise use of water should go on, people in Macau have the responsibility to act accoridng to the SAR government's initiatives to minimise waste of water in face of the threat of salt tides.
Wise use of water may start conveniently at home, as the water left from rinsing of rice makes a effective and green agent to clean vegitables and utensils. We may also start washing utensils in a basin of water instead of under a running tap. Wiping away kitchen greases with paper before washing them with water helps reduce use of water and detergents. Defrosting food may not need running tap water if it is placed in room temperature beforehand. Water left from rinsing vegitables and rice, or from shower or laundary may be gathered and used to flush the toilet.
