duce for a reasonable price. Imported water comes at a premium price, and we were importing too much outside water. If we were proactive—if we could fi nd another source of water we could con-trol—we wouldn’t have to rely so heavily on imported water. We needed a way to hedge our bets for the future, especially if the Colorado River water levels kept going down.” Th e replenishment system has accomplished this. But before Orange County offi cials could make this a reality, they had to overcome the “ick” factor, the natural revulsion consum-ers experience when hearing that they’ll be drinking water that was once wastewater. Fortunately, Orange County’s suc-cess shows that the “ick” factor is not an insurmountable barrier. Th ere are several reasons why reusing treated wastewater is becoming more com-mon, and as awareness of water scarcity grows, reuse is no longer an option, but a necessity, in areas of the country like the arid Southwest, including California, Nevada, and Texas. But there have also been dramatic improvements in the way municipalities and other water providers treat, moni-tor, and test their water quality. And these improvements are helping to ease the concerns of end users. As in Orange County, reused wastewater is treated to ultra-pure levels. In short, treatment technologies make sure that this water is as clean and safe as possible. “As a society we are becoming more environmentally conscious,” says Richard Cavagnaro, marketing manager for AdEdge Technologies in Buford, GA. “We are becoming greener, we are focusing more on sustainability. Th ose are concepts that are now mainstream. And this means that more people are looking at ways to sustain water, which is one of our most valuable resources. As part of that, more people are willing to consider reusing treated water, even for drinking water.” Th is is good news, not only for the manufacturers of treatment technolo-gies, but also for the planet as a whole. And Cavagnaro and others in the treatment and testing business say that the reuse trend isn’t about to lose its momentum. “It’s all about awareness,” says Cavagnaro. “It’s about companies and municipalities promoting that treated and reused water is acceptable, and that it is safe. We’re also seeing more success stories. Aft er seeing something work six times, it starts to become widely accepted. Th at’s what is happening with treated and reused water.” IMPROVED TECHNOLOGY IS THE KEY Water reuse supporters received good news in early 2012. That’s when a report from the National Research Council says that, thanks to advances in technol-ogy, treated wastewater—often called reclaimed wastewater—was at least as safe as traditional drinking water. The report also says that treating wastewater and reusing it for drinking water, irriga-tion, industry, and other uses could dra-matically increase the country’s available water resources. This, the report says, is particularly important in coastal areas PROVEN: Water Savings Water Re-use Pollution Reduction Scale/Corrosion/Bio Control Dolphin WaterCare ® LVDSURYHQDQGFRPSOHWHVROXWLRQWKDWGHOLYHUVDVLJQL¿FDQWLPSDFW to the bottom line and the environment.
