LID (Low impact development) may help in controlling urban storm water runoff

University of California researchers contend that LID (Low impact development) may help in controlling urban storm water runoff. LID mimic pre-urban stream functions. The researchers give the examples of green roofs that absorb and evapotranspire rainfall, rainwater harvesting tanks in homes and other buildings, use of permeable pavement for roads and parking lots. We need to capture the runoff as close to where it's generated says the researchers. Rainwater could be effectively used in homes for toilet flushing and laundry.  Using drinking water to flush toilets is literally washing our future down the drain exhorts the researchers.
