It’s estimated that 70% of freshwater withdrawals worldwide are for agricultural use. Although some see recycled wastewater as a potential solution component to global water scarcity issues, the costs of treating wastewater—to remove contaminants, reduce crop-damaging salts, and to meet health standards for reuse—often present financial limitations.

A new economic model  … Read More
