Water Scarcity Threatens China's Future - Environment - New York Times
I guess this is true of many Indian cities too. Huge suburbs in Bangalore have no water connections - they either sink their own borewells or get the water from suppliers who do that - all of this leading to rapid depletion of groundwater.
Whats the solution ? Official water supply agencies can handle only so much growth, and are hard pressed to generate enough water for current demand levels itself.
Recharge ? Its a solution that may have no immediate benefit for those doing the spending - but would lead to sustainable groundwater if done by every house, every apartment. Tough ask - who's to implement and monitor this ?
