Impose pay-per-use surcharge for water

The increase in water prices is a good attempt to reduce water usage in Singapore, but the authorities may not get the results they are hoping for (Water price must reflect scarcity, says PM Lee; March 26).

Demand for water is price inelastic. Increasing the price will not lead to a corresponding decrease in the demand.

A more effective approach would be to give incentives for reduced water usage, and impose a pay-per-use surcharge for excessive water usage.

For example, a household of four people could be allotted a certain amount of water a month; once their usage exceeds that, they could be charged, say, $5 for one litre, $10 for two litres, and so on.

This would be more effective in reducing water consumption, as it is more reasonable to be charged when they use excessive amounts of water.
