An increasing number of communities are considering direct potable reuse (DPR) systems to ensure water security and to protect public health and the environment. Utilities developing these projects need the ability to prevent disruptions from occurring, as well as the ability to respond to and recover from disruptions quickly. While operational resilience is a key consideration for water security regardless of source, the variable water quality and flow rates associated with wastewater sources present unique challenges.

Join us on Wednesday, July 11 to learn about a new Water Research Foundation report that provides DPR resilience guidance essential for any utility planning, designing or considering a DPR system. The webcast will discuss DPR resilience techniques at each stage from wastewater source control through wastewater treatment, advanced water treatment, and distribution. The presenters will also discuss application of risk assessment methods to aid decision makers in evaluating resilience enhancing alternatives and identifying alternatives associated with the maximum risk reduction per triple bottom cost (people, plant, profit).

The presentation will include discussions of

  • A resilience assessment framework that integrates risk and resilience methodology for the water industry with hazard analysis and critical control point (HACCP) analysis and reliability principles.
  • A hazard analysis catalog of actual failure modes for DPR unit treatment processes based on surveys and potential associated responses.
  • Interagency communication between DPR stages.
