The Demonstration of Direct Potable Water Reuse: The Denver Project Technical Report (1979-1993)
This report summarizes the results from Denver’s Direct Potable Water Reuse Demonstration Project. The project, conducted between 1979 and 1993, demonstrated that potable water could be reliably produced from unchlorinated secondary treated wastewater. This was a landmark for drinking water treatment and greatly furthered the understanding of water quality. The results of this research have been used by those considering this alternative to meet drinking water needs in water-short areas around the world.
The results presented here are largely from the twenty-five volume Final Report approved by the United States Environmental Protection Agency (US EPA) in April 1993. That report completed the requirements under the Cooperative Agreement between the Denver Water Department and US EPA to conduct a research project to demonstrate the feasibility of direct potable water reuse. Additional detail about the Project is available by consulting the technical literature and the Project Final Report available from Denver Water and US EPA (Cooperative Agreement CS-806821-01-4).
