Understanding our water supply and infrastructure—and how we can better assist with water conservation—is critical.

We hope you enjoy this in-depth look at California’s water supply from Luis Cetina, Metropolitan Water District of Southern California (MWD) Public Relations and Regional Affairs Representative. The presentation is approximately 45 minutes, followed by Q&A.

Recorded Wednesday, October 28, 2026

The vast majority of our surface water (70%+) originates in northern California, but most is consumed in central and southern California. Moving that water is expensive, and declining snowfall, drought, and increased demands upon the Colorado River are affecting the available supply.

Glendale purchases between 60% and 70% of its potable water from the Metropolitan Water District of Southern California (MWD), a water wholesaler.

MWD’s operational costs have increased and it must also invest in infrastructure modernization to increase local and regional water supplies. MWD raised its rates significantly in 2025 and 2026, and has proposed an additional increase effective in January, 2027. Glendale must also address its aging infrastructure, which needs significant upgrades, and plan for long-term reliability and sustainability.

Glendale’s Water Master Plan

Water conservation is a GEC issue, as drought is impacting our water supply, and even a wet El Nino season cannot undo years of below-average snowfall and rain. GEC encourages you to review Glendale’s Water Master Plan and explore ways to reduce your water consumption. About 50% of residential water consumption in CA is for outdoor irrigation. Maybe it’s time to lose your lawn and convert to drought-tolerant native plants that support native wildlife? Turf removal rebates are still available.
