Potable Reuse Research Compilation: Synthesis of Findings

The implementation of direct potable reuse (DPR), a strategy for augmenting public water supplies with advanced treated water, has been gaining traction in the water sector. Since 2012, more than US$20 million has been invested in research projects evaluating technical, operational, and managerial aspects related to DPR. By 2015, a significant body of research information was available as a result of these projects; however, the information was spread among them. Project 15-01 was undertaken in 2016 to summarize and synthesize the key issues and findings from this research to provide – in one comprehensive document – a clear understanding of the total state-of-the-art and state-of-the-science on DPR and to identify unknowns that may require further research.

This web seminar will provide an overview of the key issues, findings, and results of the research synthesis, using a topic-based approach. After a brief overview of DPR, the following topics will be addressed: source control for DPR programs, an evaluation of treatment trains, surrogates and log reduction credits for pathogens, methods to monitor pathogens, 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.
