Water recycling can reduce pressure of urban usage on fresh water resources
April 28 (UPI) -- Enhanced water recycling efforts could significantly reduce the reliance of major cities and their water demands on fresh water resources, including rivers, reservoirs and wells, according to new research. Scientists at Rice University developed models to simulate the impact of water recycling on the water usage patterns of a major urban center like Houston. The analysis -- detailed this week in the journal Nature Sustainability -- showed recycling wastewater could reduce fresh water usage by 28 percent. Authors of the new study acknowledged that water purification systems are expensive, but models showed the costs of installation and long-term energy demands would be offset by savings from municipal wastewater reuse. Houston is currently planning to reconfigure their w...
