California is building one of the largest and most controversial water projects in U.S. history — a 45-mile tunnel beneath the Sacramento–San Joaquin Delta.
Buried more than 100 feet underground and costing an estimated $25 billion, the Delta Conveyance Project is designed to protect the State Water Project, which supplies water to 27 million people and 750,000 acres of farmland.
Supporters say the tunnel is critical insurance against earthquakes, floods, sea-level rise, and climate instability. Critics argue it’s a risky bet that could reshape the Delta, shift environmental impacts, and lock California into decades of debt.
In this video, we break down:
Why California’s water system depends on the fragile Delta
How aging levees and salt intrusion threaten water supplies
What the Delta Tunnel is designed to do — and how it works
The engineering behind one of the largest tunnels ever attempted
The risks, costs, and consequences that come with it
This isn’t just an infrastructure project.
It’s a decision about who gets water, who pays for it, and how California adapts to a hotter, riskier future.
👇 Is the Delta Tunnel a smart safeguard — or a dangerous gamble?
