Singapore’s decision to raise water prices after 17 years is to be applauded. Studies show that pricing can affect behaviour, and there is strong evidence to suggest that under-priced or free water leads to very inefficient uses of water, including increased wastage.
Take the case of Doha, the capital of Qatar, where water is free. The average daily water consumption of residents is 1,200 litres.
In Singapore, domestic water consumption per capita is 151 litres, which is still relatively on the high side. According to the World Business Council for Sustainable Development, humans need a minimum of two litres of drinking water per day to survive.
