Tijuana turns wastewater into new water for Baja’s future

Tijuana’s water reuse project flows toward Baja’s future

Water is Baja’s real luxury. Forget gold chains, craft beer, or limited-edition sneakers—around here, the real status symbol is a reliable water bill. And once again, Tijuana is making headlines with a project that could reshape how the state quenches its thirst.

From wastewater to lifeline

Víctor Daniel Amador Barragán, Baja’s Secretary of Water, unveiled plans to regenerate treated water. The goal: up to 720 liters per second for potabilization and reuse. Translation? Wastewater that once got flushed away could soon flow back through the faucet. Don’t cringe. Cities worldwide already do this, and it works.

The project was presented to Mexico’s environmental authority (SEMARNAT) and the National Association of Water and Sanitation (ANEAS). It’s tied to Minute 328, the binational agreement where Mexico and the U.S. promised to finally get serious about cleaning up the Tijuana River.

Why Tijuana needs this now

Nine out of ten families in coastal Baja depend on the Colorado River. That’s like depending on one fragile straw to keep the whole state hydrated. Problem is, the Colorado is shrinking fast—think margarita glass left out in July. This project aims to reduce that dependency and give the region a fighting chance at water security.

Amador Barragán summed it up: “Water regeneration is a global trend.” In other words, Baja can’t sit this one out.

How it works

First step: rehab the Ing. Arturo Herrera and La Morita wastewater plants. Next: build a system to send treated water to the Abelardo L. Rodríguez dam. Everything must comply with Mexico’s stricter environmental rules, so no cutting corners with half-clean sludge.

If it comes together, Tijuana gets more reliable supply and less pressure on the Colorado. That means fewer last-minute water shutoffs and a little more peace of mind.

Connecting the dots with Rosarito

Last month in GGNorth, we told you about Rosarito’s Big Plan to Bring More Water to Ensenada. That project focused on moving resources south to keep wine country and Ensenada’s residents supplied.

Now, Tijuana’s new project adds another piece to the puzzle. While Rosarito works on redistribution, Tijuana is doubling down on recycling. Same endgame: stop Baja from going dry. Together, the projects paint the beginnings of a statewide water strategy instead of patchwork fixes.

Real progress or just another promise?

Of course, Baja has seen plenty of water “solutions” that never left the PowerPoint slides. But this time, there’s binational backing, updated regulations, and serious investment. That cocktail of factors gives this plan a stronger shot at becoming reality.

So no, it won’t solve everything overnight. But it’s one of the first serious moves toward long-term water security in Baja.

While you keep hauling bottled water and scolding your neighbor for watering the driveway, remember this: Tijuana’s wastewater could soon be part of the solution. And your next glass of “reused” water might just taste like progress.
