Water Utilities Division Manager City of Oceanside
Presentation Description: As part of Pure Water Oceanside, the City of Oceanside completed key portions of construction on a 4.5 MGD advanced water purification facility (expandable to 6+ MGD in the future), conveyance infrastructure, and injection and monitoring well infrastructure in December 2021 and began injecting into the Mission Groundwater Basin on December 30, 2021. While the City continues to operate the plant, they have been working to optimize operations of the plant and to troubleshoot and solve several challenges associated with a new direct-coupled advanced treatment facility using first of its kind technology. This presentation will discuss the challenges identified to date including but not limited to (1) plant automation deficiencies, (2) regulatory reporting challenges for Total Organic Content, (3) design optimization for air demands, redundancy in key equipment, (4) influent water quality considerations that impact chemical storage, (5) plant functionality consistency, (6) corrosive microbiology in the City’s aquifer, and (6) training and operations handoff challenges. The presentation will also discuss challenges with using first of its kind technology, including but not limited to predictive algorithms for disinfection procedures and ultrafiltration membranes, in water reuse projects.
