Potable reuse is becoming increasingly important as a water supply alternative throughout the United States and the world due to a combination of increased demand and uncertain supply. At the present time, all operating potable reuse projects in the U.S. utilize an environmental buffer between the advanced water treatment train and the ultimate consumer. These environmental buffers, which are typically underground aquifers or surface water storage reservoirs, provide additional contaminant mitigation and agency response time. This project identifies the benefits and tradeoffs of various treatment process trains for potable reuse.
