Meet the Suppliers: Stories of Impact
1. GreenHaiti Water Solutions: Bringing Clean Water to Rural Haiti
Tucked away in a modest office in Cap-Haïtien, GreenHaiti Water Solutions has become a household name in rural communities across northern Haiti. Founded in 2015 by engineer Marie Joseph, who grew up in a village without running water, the company started with a simple mission: "No community should have to choose between using water and getting sick." Today, GreenHaiti specializes in decentralized wastewater systems designed for small towns and villages, where large-scale infrastructure is often out of reach.
Their flagship offering? A compact effluent treatment machine equipment that can handle the wastewater of up to 500 households, using minimal energy and local materials. In the village of Marmelade, for example, GreenHaiti installed one such system in 2019. Before, residents relied on open pits that leached into the nearby river, causing frequent cholera outbreaks. Now, treated water is used to irrigate community gardens, and hospital visits for waterborne illnesses have dropped by 70%. "We don't just ｄｒｏｐ off equipment and leave," Joseph explains. "We train local teams to maintain it, so the systems last."
Beyond effluent treatment, GreenHaiti also integrates water process equipment that combines filtration and disinfection, ensuring that even the murkiest water from mountain streams becomes safe to drink. Their work in the Artibonite Valley, where farming is the lifeblood of the economy, has been transformative—farmers now use treated wastewater to water crops, turning a liability into a resource.
2. Haiti Eco-Tech Industries: Cleaning Up Urban and Industrial Spaces
In the heart of Port-au-Prince's industrial zone, Haiti Eco-Tech Industries (HETI) is on a mission to prove that manufacturing and environmental responsibility can go hand in hand. "Haiti's factories are vital for jobs, but they shouldn't poison our rivers," says CEO Jean-Pierre Louis. Since 2010, HETI has worked with textile mills, food processors, and construction companies to retrofit their operations with wastewater and air pollution control systems.
One of their most in-demand products is a wet process equipment line designed to tackle the heavy dyes and chemicals used in textile production. At a factory in Croix-des-Bouquets, HETI installed a multi-stage treatment system in 2021. Before, the factory dumped colored wastewater directly into the Rivière Grise; now, the water is so clean that local children swim in the river again. "It wasn't easy convincing owners to invest," Louis admits. "But when they saw the savings from recycling water and avoiding fines, they came around."
HETI also excels in air pollution control system equipment, crucial for factories burning fossil fuels. Their low-cost scrubbers and filters have reduced emissions by 60% at 12 industrial sites across the capital. "Our goal is to make compliance affordable," Louis adds. "Haiti can't develop if we sacrifice our environment to do it."
3. Caribbean Water Innovators: Energy-Efficient Solutions for Off-Grid Areas
For communities without reliable electricity, traditional wastewater treatment systems are a non-starter. That's where Caribbean Water Innovators (CWI) comes in. Based in Jacmel, this family-run business has spent a decade designing systems that run on solar power or even human-powered pumps, making them perfect for remote areas like La Gonâve Island.
Their signature product is a compact granulator with dry separator equipment that uses heat from the sun to evaporate water, leaving behind solid waste that can be safely composted. "In places where fuel is scarce and expensive, solar is the way to go," says co-founder Sophie Pierre. In 2023, CWI installed 10 such units in fishing villages along Haiti's southern coast. Fishermen now use treated water to clean their boats, and the compost from the dry separator enriches community gardens. "One village told us their tomatoes taste better now—turns out wastewater has great nutrients," Pierre laughs.
CWI also specializes in dry process equipment that requires little to no water, a game-changer in arid regions like the Northwest. "We don't just import solutions from abroad," Pierre emphasizes. "We adapt them to Haiti's climate. If the sun isn't shining for a week, our systems switch to a manual crank—no batteries, no fuss."
4. AquaHaiti Engineering: Protecting Coastal Ecosystems
Haiti's coasts are both a source of beauty and a lifeline for millions who depend on fishing. But untreated sewage and industrial runoff have threatened coral reefs and fish stocks for decades. AquaHaiti Engineering, based in Les Cayes, is fighting to turn the tide—literally.
The company focuses on marine wastewater treatment, using a mix of wet and dry process equipment to filter contaminants before they reach the ocean. In the town of Jacmel, for instance, AquaHaiti designed a system that treats sewage from hotels and restaurants, then redirects the clean water to irrigate nearby mangroves. "Mangroves are nature's best water filters," explains project manager Carlos Alvarez. "By working with them, we're creating a cycle that benefits both the environment and the community."
Their water process equipment is also used in fish processing plants, where blood and scales once clouded coastal waters. Now, treated water is reused to clean facilities, and solids are turned into fishmeal for local farms. "Fishermen used to complain they couldn't catch anything near the plants," Alvarez says. "Now, they're seeing more fish than in 20 years. That's the kind of change we live for."
5. Sustainable Systems Haiti: Farming Smarter, Not Harder
In Haiti's Central Plateau, where agriculture is the backbone of the economy, wastewater isn't just a problem—it's a potential resource. Sustainable Systems Haiti (SSH) has made it their mission to help farmers turn agricultural runoff into a tool for growth, rather than a source of pollution.
Using effluent treatment machine equipment and hydraulic press machines equipment, SSH designs systems that capture water from barns and fields, remove harmful pathogens, and compress organic waste into nutrient-rich briquettes. "Farmers used to let manure wash into rivers, causing algae blooms," says SSH director Mireille Duval. "Now, they use our hydraulic presses to make fertilizer, and the treated water to irrigate crops. It's a win-win."
In the town of Hinche, SSH worked with 50 small-scale farmers to install such systems in 2022. The result? Crop yields increased by 40%, and river pollution dropped significantly. "One farmer told me he used to spend $20 a month on chemical fertilizer," Duval recalls. "Now, he makes his own for free. That's the power of reusing what we once wasted."
6. Port-au-Prince Water Tech: Scaling Up for Urban Growth
As Haiti's capital continues to grow, its aging sewage infrastructure struggles to keep up. Port-au-Prince Water Tech (PPWT) is tackling this challenge head-on, specializing in high-capacity treatment plants that can handle the needs of dense neighborhoods like Pétion-Ville and Delmas.
Their largest project to date? A water process equipment upgrade at the Carrefour sewage plant, which now serves 150,000 residents in Cité Soleil. Before the upgrade, raw sewage often overflowed into streets during heavy rains, spreading disease. Now, the plant uses advanced air pollution control machines to reduce odors and a network of filters to remove 95% of contaminants. "We didn't just build a plant—we built trust," says PPWT engineer Raoul Bernard. "Residents used to avoid the area; now, kids play in the park next door."
PPWT also partners with the government to expand sewage networks into underserved areas. "Growth is inevitable," Bernard adds. "Our job is to make sure it's sustainable. Every new neighborhood deserves clean water and safe wastewater treatment."
7. Haiti Clean Water Co.: Rapid Response for Emergencies
When disaster strikes—whether a hurricane, flood, or earthquake—access to clean water becomes a matter of life and death. Haiti Clean Water Co. (HCWC), based in Gonaïves, specializes in mobile treatment units that can be deployed within 24 hours to disaster zones.
Their compact granulator with dry separator equipment is mounted on trucks, allowing teams to set up treatment sites anywhere with minimal tools. "After Hurricane Fiona in 2022, we sent 5 units to Les Cayes," says emergency response coordinator André Michel. "Roads were blocked, so we used boats to reach isolated communities. Within 3 days, we were treating 10,000 gallons of water daily." HCWC also provides auxiliary equipment like portable pumps and hoses, ensuring that even in chaos, systems stay operational.
But HCWC isn't just for emergencies. They also rent their mobile units to construction sites and music festivals, ensuring temporary gatherings don't become sources of pollution. "Haiti faces enough challenges without adding avoidable water crises," Michel says. "We're here to make sure no one is left without a solution."
8. North Haiti Environmental Systems: Bridging Rural and Urban Divides
In northern Haiti, where cities like Cap-Haïtien are growing fast but rural areas remain isolated, North Haiti Environmental Systems (NHES) has found a niche: hybrid systems that work in both settings. "A village of 500 people needs different tools than a city of 50,000," says NHES founder Jean Robert. "But they can learn from each other."
NHES offers both wet and dry process equipment, tailoring solutions to each community's needs. In rural areas, they might install a simple sand filter and constructed wetland; in small towns, a more advanced system with mechanical aerators. What truly sets them apart, though, is their training program. "We don't just sell equipment—we teach people how to fix it," Robert explains. Over the past 5 years, NHES has trained 200 local technicians, who now maintain systems in their own communities. "A technician in Milot recently modified one of our dry process units to work with local bamboo filters," Robert says proudly. "That's the innovation we need."
In Cap-Haïtien, NHES has partnered with schools to install small-scale treatment systems, turning wastewater into water for school gardens. "Kids love watching the process," Robert laughs. "They call it 'magic water.' If we can make environmentalism fun, we're winning."
9. EcoFlow Haiti: Recycling Wastewater for a Thirsty Planet
With climate change making droughts more frequent, Haiti can't afford to waste a single ｄｒｏｐ of water. EcoFlow Haiti, based in Port-de-Paix, is leading the charge in wastewater recycling, turning used water into a resource for agriculture, industry, and even drinking.
Their effluent treatment machine equipment uses a combination of filtration and UV disinfection to purify wastewater to drinking standards, though most clients use it for irrigation or industrial processes. "In the Northwest, where rainfall is unpredictable, recycled water is a lifesaver," says EcoFlow's sustainability director, Lisa Desir. In 2023, the company partnered with a banana plantation in Port-de-Paix to install a recycling system, reducing their reliance on groundwater by 60%. "The bananas are just as sweet, and the aquifer is slowly replenishing," Desir notes.
EcoFlow also uses plastic pneumatic conveying system equipment to transport solid waste from treatment plants to recycling facilities, closing the loop on sustainability. "We're not just treating water—we're creating a circular economy," Desir adds. "Every part of the process has value, and we're determined to capture it."
10. Haiti Water Futures: Innovating for Tomorrow's Challenges
For Haiti Water Futures (HWF), the future of wastewater treatment isn't just about solving today's problems—it's about anticipating tomorrow's. This research-driven company, with offices in Port-au-Prince and partnerships with Haitian universities, spends as much time in labs as it does in the field, developing cutting-edge solutions for a changing climate.
One of their latest innovations is a water process equipment line that uses nanotechnology to filter out microplastics, a growing concern in Haiti's rivers and oceans. "Traditional filters can't catch particles that small," explains lead researcher Dr. Antoine Jean. "Our nano-ceramic filters trap 99% of microplastics, ensuring they don't enter the food chain." HWF is also experimenting with air pollution control system equipment that uses locally sourced materials like volcanic rock, making it cheaper and more sustainable than imported alternatives.
But HWF doesn't just keep their innovations in-house. They share research with other suppliers and train students at the State University of Haiti. "The next great solution might come from a student in our lab," Dr. Jean says. "Haiti's water crisis is too big for one company to solve alone. We need everyone at the table."
