In the midst of a third consecutive dry year, California?EUR??,,????'?????<???EUR?s water supply continues to shrink as the state?EUR??,,????'?????<???EUR?s population grows, but according to a new report by the Natural Resources Defense Council, the state?EUR??,,????'?????<???EUR?s commercial, industrial and institutional (CII) sector has the tools to save more than enough water to meet the annual needs of Los Angeles, San Francisco and San Diego combined. Some leading California businesses and institutions are already catching on ?EUR??,,????'?????<??oe saving water and money at the same time.
?EUR??,,????'?????<?After three consecutive dry years and global warming threatening to intensify California?EUR??,,????'?????<???EUR?s droughts, we need smart-water solutions that that will stop waste and help businesses use only what they need,?EUR??,,????'?????<? said Ronnie Cohen, Director of Water Efficiency Policy for the Natural Resources Defense Council.
The CII sector uses the equivalent of more than a million Olympic-sized swimming pools of water annually. NRDC estimates California businesses could save about 25 to 50 percent of that water with efficiency measures, or as much as 700,000 -1.3 million acre-feet ?EUR??,,????'?????<??oe the equivalent to 350,000-650,000 Olympic-sized swimming pools.
While the CII sector has made some progress over the last decade, there is still a tremendous potential for improving their water efficiency and lowering their bills. For example, the report reveals: Commercial dishwashers use 25 percent of the water in commercial kitchens. A water-efficient commercial dishwasher would reduce that water use by 25 percent. If hotels install water-efficient washing machines, they can cut water use by 38 percent; Landscaping, such as at office parks, schools, parks and street medians, is responsible for one-third of the CII sector?EUR??,,????'?????<???EUR?s water use. But with smart irrigation controllers that adjust for weather conditions, commercial-sized landscapes can reduce water use by 40-50 percent.
The complete report, Making Every Drop Work: Increasing Water Efficiency in California?EUR??,,????'?????<???EUR?s Commercial, Industrial and Institutional (CII) Sector, is available online from NRDC.
