In an effort to continue its popular tour program during the novel coronavirus pandemic, while safeguarding the health and safety of its employees and the community, the Orange County Water District (OCWD) is offering virtual tours of the Groundwater Replenishment System (GWRS) in webinar format.

The virtual tours feature an in-depth look at the world-renowned GWRS through a video tour of the facility led by General Manager Mike Markus. The presentations are followed by live Q&A.

More than 100 guests attended three virtual tours during the month of November including guests from the California Special Districts Association, two nursing classes from California State University Fullerton and members of the general public who attended the monthly public tour.

Generally, virtual tours are held the first Friday of every month and are open to the general public. The January tour will be held the second Friday of the month due to the holiday. Upcoming public tours include:

  • Jan. 8 – 10:00 a.m. to 11:30 a.m.
  • Feb. 5 – 10:00 a.m. to 11:30 a.m.
  • March 5 – 10:00 a.m. to 11:30 a.m.

Registration is required for all public tours and is available through the OCWD book a tour site. For those unable to attend a virtual tour, on-demand tour videos, led by OCWD General Manager Mike Markus and staff, are available to view through the following links: on-demand GWRS general tour or on-demand GWRS technical tour.

Tours for schools and community organizations can be scheduled to accommodate group schedules. Should you have any questions or wish to obtain more information about scheduling a tour, please contact Kira Erquiaga at
