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.
