Top 10 Wastewater treatment plant Suppliers, Manufacturers, Wholesalers and Traders in Cuba

In recent years, Cuba has been steadily ramping up its efforts to build a more sustainable future—one where environmental protection and resource efficiency go hand in hand. As communities and industries across the island prioritize cleaner water systems, the demand for reliable, high-quality wastewater treatment equipment has never been higher. Behind this green movement are dedicated suppliers, manufacturers, and traders who don't just sell machines—they partner with local businesses, municipalities, and environmental agencies to turn sustainability goals into reality. Today, we're shining a light on the top 10 players in Cuba's wastewater treatment equipment scene, each bringing unique expertise, passion, and a commitment to making the island's water cleaner, one plant at a time.

1. EcoCuba Solutions

Founded in 2010 by a team of environmental engineers fresh out of Havana University, EcoCuba Solutions started with a simple mission: to make wastewater treatment accessible to even Cuba's smallest towns. What began as a tiny workshop in Matanzas has grown into a nationwide name, known for their effluent treatment machine equipment tailored to rural communities. "We saw too many villages struggling with outdated systems that couldn't keep up with their needs," says co-founder Maria Gonzalez.

Today, they've installed over 200 units across the country, from Pinar del Río to Santiago de Cuba, and their focus on affordability has made them a favorite among local governments. What really sets them apart? Their "Community Care Program," where they train local technicians to maintain the equipment, ensuring long-term success.

2. SustainableTech Pro

If there's one name that comes up when talking about industrial-grade wastewater solutions, it's SustainableTech Pro. Established in 2005, this Havana-based manufacturer specializes in water process equipment designed for factories, breweries, and agricultural processing plants—industries that generate large volumes of wastewater. "Industrial clients need tough, efficient systems that can handle heavy loads without cutting corners on compliance," explains CEO Carlos Mendez. Their flagship product? A modular water process line that can be customized to treat everything from food processing runoff to textile dye waste. One of their most notable projects was outfitting a major sugar mill in Ciego de Ávila with a system that reduced water pollution by 65% in its first year. But SustainableTech Pro doesn't stop at equipment—they also offer on-site audits to help clients identify inefficiencies, making them more than a supplier; they're a sustainability partner.

3. CubanWater Innovators

CubanWater Innovators has a reputation for thinking outside the box—and their air pollution control system equipment is a prime example. While many suppliers focus solely on water, this 2015 startup recognized that wastewater treatment plants often struggle with air quality issues too, from odors to chemical emissions. "A plant can treat water perfectly, but if it's releasing pollutants into the air, it's only solving half the problem," says lead engineer Roberto Fernandez. Their integrated systems combine wastewater treatment with air filtration, using biofilters and scrubbers to ensure both water and air meet strict environmental standards. Based in Camagüey, they've partnered with hotels in Varadero to create "green resorts" where wastewater is recycled for irrigation and air emissions are nearly eliminated. Clients love their "one-stop shop" approach—no need to coordinate with multiple vendors. Plus, their team is known for quick response times; when a hotel in Holguín had an unexpected air filter issue last year, CubanWater technicians were on-site within 24 hours.

4. GreenFlow Trading Co.

Not every business needs to manufacture equipment from scratch—sometimes, the best solutions come from curating the right tools. That's where GreenFlow Trading Co. comes in. As one of Cuba's leading wholesalers, they import and distribute top-tier water process equipment from trusted international brands, then adapt it to meet local needs. "We partner with European and Latin American manufacturers, but we never just ship and forget," says owner Luis Torres. "Our team modifies controls to work with Cuba's electrical grid, adds Spanish-language interfaces, and even creates custom maintenance guides." Founded in 2008, GreenFlow has built a loyal customer base by prioritizing transparency—they're upfront about costs, delivery times, and potential challenges. Their warehouse in Havana stocks everything from small filters to large-scale treatment tanks, meaning clients can often get what they need in days, not weeks. For businesses in a hurry, like a new dairy farm in Villa Clara that needed to start operations quickly, GreenFlow's speed and reliability have been game-changers.

5. AquaClean Cuba

AquaClean Cuba has made a name for itself by blending tradition with innovation. Founded in 1998, this family-run business in Santa Clara started by repairing old wastewater pumps but soon pivoted to manufacturing their own. Today, they're celebrated for their effluent treatment machine equipment that incorporates traditional Cuban engineering—think simple, durable designs that are easy to fix with locally available parts. "Our grandparents taught us that the best machines are the ones you can repair yourself," says third-generation owner Juanita Alvarez. "We don't overcomplicate things. Our effluent treatment units have fewer moving parts, which means less downtime and lower repair costs." This philosophy has made them a hit with small businesses, like family-owned restaurants and guest houses, who can't afford fancy, high-maintenance systems. In 2022, they launched a "Heritage Line" of equipment, paying homage to Cuba's industrial history while meeting modern environmental standards. It's this mix of old and new that keeps clients coming back.

6. CleanTech Industries

When it comes to large-scale projects, CleanTech Industries is the go-to. This Havana-based manufacturer, founded in 2003, specializes in designing and building custom wastewater treatment plants for cities and industrial zones. Their expertise includes water process equipment for high-capacity systems, like the ones powering Havana's rapidly expanding Mariel Special Development Zone. "We don't believe in one-size-fits-all," says project manager Diego Ramirez. "Every plant we build is unique, tailored to the community's water usage, local climate, and long-term goals." One of their most ambitious projects was the 2021 upgrade of Santiago de Cuba's main wastewater plant, which now treats 50% more water than before while using 30% less energy. CleanTech is also a pioneer in using solar power to run their equipment, aligning with Cuba's push for renewable energy. Clients praise their attention to detail—they even include public education components, like tours of the plants, to help communities understand and value the work being done.

7. Havana Environmental Systems (HES)

Havana Environmental Systems, or HES, has a secret weapon: their in-house research lab. Founded in 2012 as a spin-off from the University of Havana's Environmental Science Department, HES is all about innovation. Their team of 15 researchers is constantly experimenting with new materials and technologies, and their latest breakthrough is a water process equipment line that uses nanotechnology to filter out microplastics—an emerging concern in Cuba's waterways. "We noticed that traditional filters weren't catching these tiny particles, so we got to work," explains lab director Dr. Elena Suarez. The result? A "NanoFilter Pro" system that's now being tested in Cienfuegos Bay, a critical ecosystem for local fisheries. HES also partners with international NGOs to stay ahead of global trends, recently collaborating with a Canadian team to adapt their technology for cold climates (useful for Cuba's mountainous regions). While they're still a smaller player compared to some competitors, their focus on cutting-edge solutions has earned them a spot on this list—and a reputation as Cuba's "future of water treatment."

8. ProEco Trading

ProEco Trading is proof that you don't need to be the biggest to make a big impact. This small wholesaler, based in Holguín since 2015, specializes in importing and distributing niche equipment, including air pollution control system equipment for wastewater plants. "We saw a gap in the market—most suppliers focus on water, but the air around treatment plants matters too," says owner Pedro Herrera. ProEco partners with a Mexican manufacturer to bring in compact, energy-efficient air scrubbers that neutralize odors and reduce harmful emissions. Their clients range from small wastewater facilities in Guantánamo to large resorts in Varadero, where keeping the air fresh is key for tourism. What makes ProEco stand out is their dedication to customer service. "We don't just sell you a scrubber and wave goodbye," Pedro adds. "We follow up every month to make sure it's working, and we even offer free replacement filters for the first year." For businesses that value personalized care, ProEco is a breath of fresh air (pun intended).

9. Matanzas Water Works

Matanzas Water Works has deep roots in Cuba's industrial heartland. Founded in 1985, this manufacturer got its start building equipment for the province's sugar mills and refineries, but in the 2000s, they shifted focus to environmental solutions. Today, they're a leader in effluent treatment machine equipment for heavy industries, like oil refineries and chemical plants. "These industries produce some of the toughest wastewater to treat—high in chemicals, heavy metals, and other contaminants," says plant manager Ricardo Gomez. "Our equipment is built to handle that intensity, with robust filters and chemical treatment systems that meet strict international standards." One of their most notable clients is the Cienfuegos Oil Refinery, where their effluent treatment system has helped reduce toxic discharge by 80% since 2018. Matanzas Water Works also prides itself on training—they offer free workshops for client staff, ensuring everyone knows how to operate and maintain the equipment safely. It's this combination of strength and support that has kept them a trusted name for over 35 years.
