About Us
Baja's Water Filtration Specialists
A local family business based in Rosarito — built for Baja California's water, not warehoused thousands of miles away.
Serving Rosarito and all of Baja California.
Who We Are
Built for this region
Baja Water Systems was founded to solve a problem that generic water companies don't address: water quality in Rosarito and Baja California is fundamentally different from what most homeowners are used to. Cisterns, tinacos, aging distribution infrastructure, and seasonal variation all affect what comes out of your tap — and they require a local solution, not a one-size-fits-all product shipped from a warehouse.
We test before we recommend. We install what your water actually needs. And we stay on through maintenance so your system performs the same in year three as it did on day one.
Inspection
We inspect your water supply to identify contaminants, pressure issues, and system needs before recommending any solution.
Installation
Proper installation matters as much as the equipment itself. We install filtration systems cleanly and correctly, tuned to your plumbing layout and Baja's unique water conditions.
Maintenance
Regular maintenance keeps your system performing properly and extends its lifespan. We handle filter changes, checkups, and service so your water stays clean year-round.
Support
If something changes with your water — pressure drop, taste, or clarity — call us. We respond quickly and diagnose the issue on-site.
What We Install
Equipment we trust in our own homes
We primarily install iSpring whole-house filtration, RO drinking systems, and UV sterilization. NSF-certified, proven in Baja conditions, and supported by a parts and cartridge inventory we keep stocked locally in Rosarito — so a worn UV lamp or expired cartridge doesn't mean weeks of cross-border shipping.
If iSpring doesn't cover a need, we source the right equipment for the job and explain exactly what we picked and why.
Our Commitment
Clean water is a local responsibility
Rosarito is our home too. We live and work in this community, and every system we install is one we stand behind personally. Our commitment is simple: we don't sell equipment you don't need, we don't disappear after installation, and we price our service so that clean water is accessible to expats and local families alike.
We serve Rosarito, Tijuana, Playas de Tijuana and Ensenada — the homes from Playas de Tijuana down through the Rosarito corridor and into Ensenada.
Baja Water. Fixed.
We install the right system for your home and keep it running. No upselling, no guesswork, no chasing a service team that's three states away.
