Researchers compared California’s water conservation efforts with two options: banning landscape irrigation and expanding the use of alternative water sources, such as desalination and recycled water.
Seventy-six percent of Californians believe recycled water should be used as a long-term solution for managing water resources, regardless of whether a water shortage continues.
The groups’ letter said that recycled water projects proposed by 92 agencies in 14 states could produce more than 900,000 acre-feet of additional water supply.
The organization will fund research examining whether water resource recovery facilities experience difficulties in dewatering anaerobically digested biosolids.
The report says regulations are not keeping up with advances in technologies and their use, hindering the capacity for graywater and stormwater to significantly expand the nation’s water supplies.
