Join us April 15 for an in-depth look at the City of Tustin's Main Street Plant, presented by Mike Chandler, Water Services Manager for the City of Tustin.
The City of Tustin’s Main Street Plant has undergone a major transformation from a legacy nitrate treatment facility into a centralized regional treatment hub designed to address emerging PFAS regulations while maintaining nitrate compliance and distribution reliability. In response to PFAS contaminants within the OC Groundwater Basin and in partnership with Orange County Water District, the City & OCWD designed and constructed a multi-train ion exchange system for PFAS removal, a fully automated nitrate ion exchange system, upgraded existing booster pumping capacity, and converted disinfection from chlorine gas to sodium hypochlorite for enhanced safety and operational resilience.
This technical presentation will walk through the design criteria, hydraulic considerations, monitoring approach, operational lessons learned, and lifecycle considerations associated with centralized treatment in a constrained footprint. Attendees will gain insight into real-world implementation challenges, conservative compliance strategies, and practical operational takeaways applicable to utilities facing similar PFAS and nitrate treatment decisions.
Key topics covered include:
-
Design criteria and hydraulic considerations for centralized PFAS and nitrate treatment
-
Ion exchange system design and automated nitrate removal
-
Monitoring approach and conservative compliance strategies
-
Disinfection conversion from chlorine gas to sodium hypochlorite
-
Operational lessons learned and lifecycle considerations in a constrained footprint
This case study demonstrates how a municipal utility can successfully navigate complex regulatory requirements, multi-agency partnerships, and site constraints to deliver a resilient, future-ready treatment facility. The operational takeaways presented are directly applicable to any water agency facing PFAS or nitrate treatment decisions in today's regulatory environment.
Our April presentation promises to be both informative and immediately applicable to utilities across the region. Make your reservations today!
