Understanding Advanced Purified Water Treatment
How It Can Be a Key Part of Our Water Supply Solution
Nevada has decades of experience producing high-quality drinking water and recycled, or reclaimed, water. In 2016, new regulations were adopted to permit use of “exceptional quality reclaimed water,” or advanced purified water, for groundwater augmentation. Advanced purified water is achieved through multiple water treatment steps and natural purification processes.
The feasibility study will occur over the next 2-3 years. It consists of multiple elements including technical, social, environmental and financial analyses, regulatory compliance, public engagement, advanced treatment pilot testing, geotechnical investigations, and field scale treatment demonstration projects.
Safe, Reliable, Sustainable
Many regions around the world are experiencing drought and the resulting lack of water supplies. Proven engineered and natural treatment processes that purify reclaimed water help provide a sustainable water supply. Although using purified water for drinking is not new, innovative projects in Australia, Texas, California and elsewhere are successful examples of advanced purified practices being used to diversify water portfolios.
OneWater Nevada, in partnership with local northern Nevada agencies and the University of Nevada, Reno, is looking to develop new, potential options to ensure a future water supply for the diverse and world-class Truckee Meadows area.
Field Scale Demonstration Trailers Will be Used to Inform the Public
The University of Nevada, Reno will lead the treatment technology evaluations and water quality testing and compliance programs. Each demonstration project is envisioned to operate 9-12 months. Multiple trailers will be equipped with advanced water purification technology as illustrated below.
After the advanced treatment process, the purified water will be introduced to local groundwater at a small scale for an extended period of time. This allows the environment to naturally filter the purified water, adding yet another treatment step.
- Filtration: Solids are filtered out in this initial step toward purification.
- Ozone-BAC: Ozonation with biological treatment removes organic matter and chemicals.
- Granular Activated Carbon: Acts as a final polishing step.
- Ultraviolet Light: Ultraviolet light inactivates viruses and breaks down trace organic compounds.
