Framework for Direct Potable Reuse

September 2015

This 190-page guidance document address the emerging practice of direct potable reuse (DPR). DPR involves state-of-the art advanced water treatment technologies, such as membranes, reverse osmosis, and advanced oxidation, to remove viruses, bacteria, chemicals, and other contaminants that may be present in wastewater.

The document provides a context for DPR, including the costs, benefits, energy requirements, and comparative issues with other water sources and measures.

The document is the result of a collaborative effort among

  • the WateReuse Association,
  • the National Water Research Institute (NWRI),
  • the American Water Works Association (AWWA), and
  • the Water Environment Federation (WEF).


In addition to the comprehensive 170-page report, the collaborators created a 4-page summary document.
