Keeping in mind the limitations on increasing water supply, Prime Minister Manmohan Singh Tuesday said that a large part of effort to plug the demand-supply gap must focus on increasing water use efficiency.

“There is no regulation of ground water extraction and no coordination among competing uses. Inadequate and sub-optimal pricing of both power and water is promoting the misuse of groundwater. We need to move to a situation where groundwater can be treated as a common property resource,” he said while inaugurating the first National Water Week.
