Good report from the Natural Resources Defense Council - - Capturing Rainwater From Rooftops.
It will be interesting if this holds up - - "If all rooftops in these cities {the report looked at eight cities} captured rainwater, it would meet the water supply needs of 21% to 75% of each city's population."
The era of rain barrels and cisterns to ease water shortages and prevent pollution. The era of decentralization - - my water is not your water.
