Evaluating the Potential of Direct Potable Reuse in Texas, Texas Water Development Board, et al

This project brought together a team of national and international experts working with the Texas Water Development Board (TWDB), 12 utility sponsors, WateReuse Texas, and the Texas Commission on Environmental Quality to develop a resource document for direct potable reuse (DPR). The document is a technical resource for utilities, consultants, planners, academicians, and other parties interested in evaluating the feasibility of implementing DPR or for utilities that have determined that DPR, is feasible and are entering the planning phase of a project. The resource document focuses on key topics for development of direct potable reuse, including:

  • Relevance of chemical contaminants of concern 6 Water quality performance targets
  • Enhanced source control
  • Treatment strategies
  • Risk assessment examples
  • Pilot- and bench-scale testing
  • Regulatory and legal considerations
  • Public outreach

As part of the project APAI facilitated two all-day workshops with the technical experts and project stakeholders to develop a consensus on two key project elements — water quality performance targets and treatment strategies. APAI’s project manager, Ellen McDonald, moderated these sessions at which the technical experts presented on specific topics and served on panels to allow for interactive question and answer sessions with stakeholders.

The document produced was developed to be very accessible to readers not familiar with the technical details of DPR. Volume 1 provides an overview and key information on each topic, and Volume 2 contains appendices with more detailed technical information.  The document is available for download from TWDB’s website at the links below:
