There is a technology that removes arsenic, fluoride, and heavy metals from your water without wasting a single drop. Mexico has been waiting for it.
Walk into almost any home in Mexico and you’ll find the same scene: a reverse osmosis system humming under the kitchen sink, quietly discarding 50 to 70 percent of every liter it processes down the drain. Or a household spending upward of $1,000 MXN every month hauling garrafones from the nearest dispenser—water produced by Pepsi or Coca-Cola through those same wasteful systems at industrial scale.
This is the status quo. And for a country where 39% of groundwater already exceeds safe contamination limits and aquifers are depleting by meters every year, it is a status quo that cannot hold.
Acuario was built to replace it.
A Different Kind of Technology
Acuario’s purification system is built on two interconnected processes: electrolysis and electrocoagulation. Together, they form a treatment approach that is fundamentally different from anything currently available in the residential water purification market—and far more effective for the specific contamination challenges Mexico faces.
Electrolysis is the foundation. By passing an electrical current through water, Acuario’s system generates powerful purifying agents directly within the water itself—no chemicals added, no external reagents required. The electricity does the work. The water provides the medium. The contaminants don’t stand a chance.
Electrocoagulation takes this a step further. As the electrical current moves through the water, it produces microscopic coagulating particles with an extraordinary affinity for contaminants. Arsenic molecules adsorb onto their surface. Fluoride precipitates out of solution and binds to the forming clusters. Heavy metals like lead and mercury attach and aggregate. Meanwhile, tiny oxygen micro-bubbles rise through the water, carrying contaminated particles toward the surface where they are captured and removed. Bacteria and viruses are destroyed by the oxidizing environment the process creates— without a single drop of chemical treatment.
What makes this combination so powerful—and so well-suited to Mexico—is that it happens in real-time as water flows continuously through the system. There are no membranes to restrict pressure, no chemicals to replenish, no storage tanks to wait for. The process is always active, always purifying, always delivering.
What It Removes
Mexico’s water contamination is not a single problem. It is a layered crisis that varies by region, by depth of well, by season, and by infrastructure. Acuario was designed with this complexity in mind.
The system removes arsenic, one of Mexico’s most widespread and dangerous groundwater threats. It eliminates fluoride that causes dental and skeletal fluorosis, the degenerative condition visible in communities across Guanajuato and Chihuahua where generations have consumed contaminated groundwater. It removes lead and mercury that accumulate silently in organs over years of exposure. And it destroys bacterial contamination—E. coli, coliforms, and pathogens—that conventional carbon filters and even UV systems cannot fully address.
Critically, Acuario does this while preserving the beneficial minerals that reverse osmosis strips away. Calcium, magnesium, potassium—the minerals your body needs—remain in the water. The result is not the flat, lifeless taste of RO water or distilled water. It is water that tastes the way water should: clean, fresh, and minerally alive.
Zero Waste. Full Stop.
The most significant distinction between Acuario and every other purification system on the market is this: when water goes in, all of it comes out clean.
There is no reject stream. No brine discharge. No percentage of every liter sacrificed to the drain. In a nation facing genuine water scarcity—where cities ration water, where rural communities have watched wells run dry, where the political and environmental cost of water depletion is rising—zero waste is not a marketing claim. It is a moral position.
Reverse osmosis, the technology installed in millions of Mexican homes and businesses, wastes more water than it delivers. Every liter of purified RO water produced discards between one and three liters as contaminated waste. At the household level this seems manageable. At national scale, across millions of systems running daily, the cumulative waste is staggering.
Acuario refuses to participate in this calculus.
Built to Last
Acuario systems are engineered for a lifespan of 20 years or more. There are no membranes to replace every two to three years. No UV bulbs that burn out annually. No filter cartridges that clog and reduce flow over time. The electrolysis electrodes are designed for decades of continuous operation with minimal maintenance and no consumable parts.
This longevity translates to lower total cost of ownership, less waste entering landfills, and a single installation decision that protects a family’s water quality for a generation.
An Accessible Model
Technology alone does not solve a water crisis. Distribution does.
Acuario has taken this seriously from the beginning. Alongside residential installations, Acuario operates water fill stations across Bahía de Banderas on an honesty system: customers pay what they can afford and take what they need. No price barriers. No gatekeeping. Clean, mineral-rich water available to every member of the community regardless of income.
It is a model built on trust. And it is working.
Hundreds of homes across Nayarit have already made the switch. Local technicians install and maintain the systems. Local manufacturing ensures quality control and creates economic opportunity within the communities Acuario serves.
The Bigger Picture
Mexico is running out of time for half-measures. The contamination crisis is real, documented, and spreading as aquifers are forced deeper into more heavily mineralized geological layers. The scarcity crisis is real, intensifying with climate change and agricultural demand that shows no signs of slowing. And the solutions the market currently offers—wasteful, expensive, inadequate—are not designed for Mexico’s reality.
Acuario is.
Zero waste. Full contaminant removal. Mineral preservation. Twenty-year lifespan. High-flow performance. Local manufacturing. Community access.
This is what water purification should look like in Mexico. This is what it now can look like. For more information about Acuario’s water purification systems, visit www.acuario.io
