NWRI White Paper on "Direct Potable Reuse: Benefits for Public Water Supplies, Agriculture, the Environment, and Energy Conservation"
This 20-page NWRI White Paper (2012) focuses on the role that direct potable reuse (DPR) can have in the management of water resources in the future. Using a case study based on Southern California, the authors point out that the potential benefits accrued for agriculture, environmental preservation and enhancement, and energy conservation through the application of DPR may be even more important than its ability to provide an alternative supply of water.

Direct Potable Reuse Workshop: Workshop Report
This 41-page report was prepared by California Urban Water Agencies, National Water Research Institute, and WateReuse California to summarize the results of a workshop held on April 26-27, 2010, for the purpose of identifying information gaps and existing barriers that need to be addressed to develop direct potable reuse regulations in California. Information gathered from this workshop is expected to help support the needs of water, wastewater, and recycled water agencies in long-term planning and in prioritizing research-related activities.
