Water webinars

Join OCWD for its webinar series featuring emerging and newsworthy topics. Hear from OCWD experts and District partners as they discuss important OCWD programs and projects that impact your water supply. Whether you are an elected official, water industry professional, researcher, consultant, student, or community member, there is something for everyone. Webinars last approximately one hour and are free to attend. 



California is in the midst of the most severe drought on record and historic water restrictions have been implemented across the state. From maximizing current water supplies to developing new water supply infrastructure, everything must be on the table to ensure long-term reliability of our water supplies for future generations. Our speakers will discuss the status of current statewide and regional water supplies and actions that are taking place to ensure water resiliency in Orange County, Southern California, and beyond. 


  • John Kennedy, Executive Director of Engineering and Water Resources, Orange County Water District
  • Demetri Polyzos, Team Manager, Water Resource Management Group, Metropolitan Water District of Southern California
