The demand for water outside of California, along with environmental needs, is reducing Southern California?EUR??,,????'???s imported water supplies, according to the UCLA Institute of the Environment Researchers?EUR??,,????'??? Southern California Environmental Report Card for 2002. Water reclamation, or the reuse of highly treated wastewater, potentially can provide new supplies equal to approximately 50 percent of Southern California?EUR??,,????'???s water consumption. ?EUR??,,????'??There is a lesson to be learned from the recent energy crisis,?EUR??,,????'?? researchers Michael Stenstrom and Richard Berk wrote. ?EUR??,,????'??We did not construct the needed electricity-generating infrastructure of implement the necessary conservation to provide for the future. The same thing is occurring with water supply. Water-reclamation plants take just as long to construct as electricity-generating plants, and water is much less transportable than electricity.?EUR??,,????'?? Researchers also warned that California?EUR??,,????'???s drought could be more severe and longer than those in the past, and that ?EUR??,,????'??the problem it creates could make our electricity shortage seem trivial by comparison.?EUR??,,????'??
