The highest water-use efficiency of more than $50 per cubic metre is in Oceania, Australia, New Zealand, Singapore, Israel, Denmark, Finland, and Great Britain while the lowest is in Central and South Asia, including India, at less than $10 per cubic metre.
Under the 12th Plan, the government had proposed setting up a National Bureau of Water Use Efficiency as part of the Implementation of National Water Mission. However, the idea was put on the back burner after much discussion.
The new Jal Shakti Ministry, however, has started drawing up the broad framework of such a bureau on the lines of a similar body — The Bureau of Energy Efficiency. Some of the main objectives of the Bureau of Water Efficiency would be to improve water-use efficiency in irrigation and industrial activities. The government is also considering creating a mechanism for water-efficiency labelling in municipal and household sectors.
