Direct Potable Reuse (DPR) is the supply of highly treated reclaimed water directly to a drinking water treatment plant or distribution system, with or without an engineered storage buffer. This differs from Indirect Potable Reuse (IPR) which is already practiced in many areas of the United States and involves the inclusion of an environmental buffer (such as a lake, reservoir or aquifer) prior to arriving at the intake of a drinking water treatment plant. There are a number of potential benefits of DPR relative to IPR, including reduced energy requirements, reduced construction costs and reduced operational costs. DPR may even provide an opportunity to allow potable reuse in situations where a suitable environmental buffer is not available for IPR.

All water treatment facilities require a high level of reliability to ensure water is delivered to an acceptable quality and the risk to public health is minimized. This importance is underlined in the case of DPR, where the real risks of higher contaminant levels in plant feed water (e.g., during epidemics or after industrial accidents), along with perceived risks associated with public perception of reuse, require a high level of operational certainty. Consistent and assured levels of reliability can be met only with a holistic asset management framework including a robust design, effective and transparent operational management, a carefully managed maintenance strategy, and proven response procedures.

The critical control point methodology, adapted from the food industry, provides a process that focuses and helps assure that water quality consistently meets the requirements of public health. This webcast will present some of the work of the WateReuse Research Foundation study Critical Control Point Assessment to Quantify Robustness and Reliability of Multiple Treatment Barriers of a DPR Scheme (13-03) along with information from  Development of Operation and Maintenance Plan and Training and Certification Framework for Direct Potable Reuse Systems (13-13).
