Inspection Trips

Each year, Central Basin and the Metropolitan Water District host inspection trips to Southern California's water delivery systems. During the behind-the-scenes educational tours, community leaders have the unique opportunity to sit down with industry experts to discuss pressing water issues and policies. Additionally, stakeholders tour the massive infrastructure that brings water straight to our homes. 

The inspection trips that are typically offered include: the Colorado River Aqueduct, State Water Project and Diamond Valley Lake. Local tours to Central Basin's facilities are also offered.
