The Water Environment & Reuse Foundation (WE&RF) (formerly, the WateReuse Research Foundation) invested in a research portfolio valued at over $24 million to investigate different aspects of the technical feasibility of implementing direct potable reuse (DPR) projects. The purpose of this report is to summarize and synthesize key issues and findings from this research, as well as the results of complementary research, to provide a clear understanding of the state-of-the-art and state-of-the-science on DPR and to identify unknowns that may require further research.

The topics addressed in this report include: source control, treatment trains, surrogates and log reduction credits for pathogens, pathogen monitoring, constituents of emerging concern, critical control points to monitor DPR systems, operation and maintenance of DPR facilities, operator training and certification, the resilience of DPR systems, and reliable and redundant treatment train performance.
