NorthStar Water Tech has been a cornerstone of Ontario’s water treatment industry since 1998. With headquarters in Toronto and manufacturing facilities in Hamilton, the company has built a reputation for rugged, cold-weather-resistant equipment—critical for Canada’s harsh winters.

NorthStar’s expertise lies in balancing wet process and dry process equipment , giving clients flexibility based on their water availability and waste composition. Their wet process systems, ideal for high-moisture industrial waste, use chemical coagulation and sedimentation to separate solids, while their dry process equipment relies on thermal drying for applications where water conservation is key. For instance, a mining operation in Sudbury switched to NorthStar’s dry process system and cut water consumption by 45%, a game-changer in a region where freshwater is scarce.

Municipal clients praise NorthStar’s reliability. The City of Ottawa’s Greenboro Wastewater Plant upgraded to NorthStar’s NS-5000 effluent treatment machine equipment in 2020, which handles 180,000 cubic meters of wastewater daily. The system’s smart monitoring features send real-time data to operators’ phones, reducing downtime and improving response times to fluctuations in flow. “During last year’s spring floods, the system automatically adjusted chemical dosages to handle the increased sediment load,” notes Ottawa’s water treatment director. “We avoided a potential overflow, and that’s priceless for public health.”

NorthStar also prioritizes local partnerships. The company works closely with Canadian universities to研发 new filtration technologies, and 90% of its components are sourced from North American suppliers. This commitment to domestic manufacturing has earned them contracts with the Canadian Armed Forces, providing mobile wastewater treatment units for remote military bases.

Maple Clean Systems, established in 1992, has deep roots in Quebec’s industrial sector. Specializing in heavy-duty effluent treatment machine equipment for manufacturing and chemical plants, Maple Clean has earned a reputation for tackling the toughest wastewater challenges.

One area where Maple Clean excels is in handling toxic or hazardous effluents. Their MC-Toxic series uses advanced oxidation processes and activated carbon filtration to neutralize heavy metals, solvents, and organic compounds—common byproducts in chemical and pharmaceutical manufacturing. A Montreal-based paint factory, for example, was struggling to meet federal guidelines for lead and volatile organic compounds (VOCs) until they installed Maple Clean’s system. Today, their effluent is so clean it’s reused in the factory’s rinsing processes, saving over 2 million liters of water annually.

Maple Clean’s wet process equipment is also a hit in the pulp and paper industry. The company’s proprietary “BioPulp” system combines anaerobic digestion with membrane bioreactors to break down lignin and other wood-derived compounds, reducing sludge production by up to 60%. A paper mill in Trois-Rivières reported annual savings of $400,000 in disposal costs after switching to BioPulp. “Sludge removal used to be a logistical nightmare,” says the mill’s environmental manager. “Now, we produce so little that we can compost what’s left—Maple Clean turned a liability into a resource.”

Beyond equipment, Maple Clean offers comprehensive consulting services. Their team of environmental engineers conducts on-site audits to identify inefficiencies before recommending solutions. For a mining company in northern Quebec, this meant redesigning their entire wastewater流程 to integrate Maple Clean’s equipment with existing infrastructure, saving the client over $1.2 million in construction costs.

As a Quebec-based company, Maple Clean is also bilingual, providing seamless support in both English and French—a crucial advantage for clients across Canada’s diverse linguistic landscape.

While many suppliers focus on large-scale operations, Polaris Environmental, founded in 2010, has carved a niche in serving remote and rural communities across Western Canada. Based in Edmonton, the company specializes in compact, energy-efficient water process equipment designed for areas with limited infrastructure.

Polaris’s claim to fame is its PE-Mini series of effluent treatment machine equipment , which can treat up to 50,000 liters of wastewater per day in a footprint smaller than a shipping container. These systems are perfect for remote mining camps, Indigenous communities, and small towns that lack access to centralized treatment plants. In the Yukon, for example, Polaris installed 12 PE-Mini units in communities along the Alaska Highway, replacing outdated septic systems and reducing contamination of the Yukon River watershed.

What makes Polaris unique is its focus on sustainability in remote settings. Many of their systems are solar-powered or hybrid (solar/diesel), reducing reliance on grid electricity in off-grid locations. The company also uses locally sourced materials where possible; their PE-Mini units, for instance, feature insulation made from recycled Canadian sheep’s wool, improving heat retention in sub-zero temperatures.

Polaris isn’t just about small-scale solutions, though. The company has recently expanded into the oil and gas sector, offering compact wet process equipment for fracking wastewater treatment. Their mobile systems can be transported to remote drill sites, treating and recycling water on-site to reduce trucking and freshwater withdrawals. A major energy company in Alberta reported a 40% reduction in water trucking costs after partnering with Polaris—all while lowering their environmental footprint.

Customer support is another Polaris strength. The company offers remote monitoring via satellite for clients in isolated areas, and their technicians are on call 24/7 for emergency repairs. “When your nearest service center is 800 kilometers away, you need a supplier you can trust,” says the mayor of a small Yukon community. “Polaris has never let us down.”

Rounding out our list is GreenStream Innovations, a Halifax-based company that’s making waves in coastal and marine wastewater treatment. Founded in 2012, GreenStream specializes in water process equipment for ports, marinas, and offshore platforms—areas where saltwater intrusion and strict discharge regulations demand specialized solutions.

GreenStream’s flagship product is the GS-Marine series, a compact treatment system designed for ships and offshore rigs. Using a combination of wet process equipment and advanced membrane filtration, the GS-Marine can treat blackwater (sewage) and greywater (shower/kitchen water) to meet International Maritime Organization (IMO) standards, allowing vessels to discharge treated water even in protected marine areas. The Canadian Coast Guard now uses GreenStream’s systems on its icebreakers, ensuring operations in the Arctic don’t harm fragile ecosystems.

On land, GreenStream is a leader in coastal community treatment. Their GS-Coastal system is built to withstand saltwater corrosion and storm surges, making it ideal for Atlantic Canada’s harsh coastal climate. The town of Lunenburg, NS, recently upgraded its wastewater plant with GreenStream’s equipment, which now treats 1.2 million liters of sewage daily before releasing it into the Atlantic. The upgrade included a nutrient recovery system that captures nitrogen and phosphorus to fertilize local community gardens—a closed-loop solution that turns waste into a resource.

GreenStream also prioritizes research and development. The company partners with Dalhousie University’s Marine Environmental Science program to test new filtration materials, including algae-based membranes that naturally absorb heavy metals. This innovative approach has earned GreenStream funding from the Canadian Ocean Supercluster, a government initiative to boost marine technology innovation.

As climate change brings more extreme weather, GreenStream is adapting. Their newest system, the GS-Resilient, includes backup generators and flood-resistant design features to ensure continuous operation during hurricanes or nor’easters—a critical advantage for coastal communities facing rising sea levels.

With so many options, selecting a sewage treatment equipment supplier can feel overwhelming. Here are a few key factors to consider:

Regulatory Compliance: Ensure the supplier’s equipment meets federal (CEPA) and provincial (e.g., Ontario’s MOECC, BC’s EAO) standards. Look for certifications like ISO 9001 (quality management) and ISO 14001 (environmental management).

Customization: Every wastewater stream is unique. A good supplier will conduct a detailed analysis of your effluent before recommending a solution. For example, a dairy farm will need different equipment than a metal plating facility.

Support and Maintenance: Equipment downtime can be costly. Ask about warranty terms, response times for repairs, and availability of replacement parts. Suppliers with local service centers (like NorthStar and Maple Clean) often provide faster support.

Sustainability: Look for suppliers that prioritize energy efficiency, water recycling, and waste reduction. Systems that recover resources (like nutrients or energy) can offer long-term cost savings while benefiting the environment.

Ultimately, the best supplier is one that views your project as a partnership, not just a sale. Whether you’re a small town in the Yukon or a major industrial facility in Ontario, the companies on this list have the expertise, innovation, and commitment to help you meet your wastewater treatment goals.
