With numerous potable water reuse facilities being planned, designed, and constructed, there are questions regarding how to best implement enhanced source control programs for potable water reuse. A critical next step in the evolution of enhanced source control is developing the ability to monitor water quality within the wastewater collection system cost-effectively in real time. This project will determine what level of real-time collection system monitoring is feasible, appropriate, and necessary for protection of downstream potable reuse; and develop a framework for integrating real-time monitoring into existing pre-treatment program requirements (permits, local limits, etc.), including data management and security considerations.
