The water crisis in Mexico is not a threat for the future but an everyday reality. Droughts, extreme rainfall events and rising temperatures are becoming more frequent and putting pressure on water supplies. In Mexico, more than 10% of the population, some 15 million people, lack access to potable water and the country’s main basins have a deficit of almost 600 million cubic meters. Agriculture accounts for 76% of the country’s freshwater and of the 653 groundwater aquifers in Mexico, 105 are overexploited and 32 are facing salinization problems.
It’s a big issue. But innovation is also taking place at the grassroots level. From smart leak detection systems to decentralized wastewater treatment and rainwater harvesting, Mexican companies and international partners are developing solutions that work. The market is driven by stringent environmental regulations, increasing industrial activities and growing awareness about sustainable practices.
If you’re looking for water treatment and management partners in Mexico, here are five companies at the forefront.
1. Grupo Rotoplas
Grupo Rotoplas is the quintessential water success story in Mexico. Established in 1978 and based in Mexico City, the company has more than 45 years of experience positioning itself as the preeminent provider of water solutions throughout the Americas. The company has more than 3,200 employees and is traded on the Mexican stock exchange under the symbol AGUA.
And their product portfolio is so comprehensive. Rotoplas is best known for their iconic water storage tanks, but they’ve grown much beyond that. They provide advanced purification systems featuring their proprietary Hydropur® technology, a blend of activated carbon and colloidal silver, which eliminates chlorine and checks bacterial growth. For more difficult water conditions, they offer robust five-stage Reverse Osmosis systems certified by Mexico’s COFEPRIS (NOM 244) and the international NSF.
The real difference-maker for Rotoplas is its distribution network. They’ve infiltrated all of the hardware and plumbing supply chain in Mexico, delivering their products to the most remote communities. In a bold move, the company has launched Bebbia, a subscription-based “water-as-a-service” model that delivers purified water right into the home—taking on the traditional bottled water market.
The company is most profitable from its individual solutions segment and Mexico is its largest geographic market.

Why Mexico’s Water Sector Matters Now
Mexico’s water problems are mounting. A study in 2025 found that 70% of surface water bodies in Mexico are contaminated to some extent . Major risks to water security include overexploitation, salinization and contamination. The country is experiencing the effects of climate change, with average temperatures rising more than 1.5°C since the Industrial Revolution.
The good news is that some solutions are beginning to emerge. The Mexican government is taking ambitious programs in response. CONAGUA’s National Program for Field Technification, called “México se Tecnifica,” aims to modernize more than 200,000 hectares across 17 priority irrigation districts. The program represents an investment of 58,975 million pesos for the 2025-2030 period and seeks to recover some 2.8 billion cubic meters of water, equivalent to three times the annual supply of Mexico City.
In Mexico, water treatment technologies in use include reverse osmosis, UV treatment, membrane filtration, activated carbon, biological treatment and membrane bioreactors. Key end-use industries driving the demand include oil and gas, chemicals, mining, power generation, pulp and paper, food and beverage and pharmaceuticals.
The companies showcased here demonstrate the breadth and scale of Mexico’s water treatment and management industry—from local companies such as Grupo Rotoplas to international companies such as Veolia and Kurita and specialized Mexican suppliers like Hydrocon and Acuanovus. They show that Mexico’s water future is about thriving, enabled by innovation and collaboration.
