Corrosive environments, rising treatment demands, and aging infrastructure make reliable wastewater storage more important than ever.
Greatario’s wastewater storage tank and sewage tank treatment solutions are designed to handle the toughest conditions and deliver long-term durability, low maintenance, and full compliance. From clarifiers to sludge tanks, our systems are trusted across Canada for municipal and industrial wastewater applications.

Across Canada, aging wastewater infrastructure is under growing pressure. Many municipal sewage systems were built decades ago and weren’t designed for today’s population growth, storm surges, or tightening environmental regulations. At the same time, industrial facilities are facing higher scrutiny around waste discharge and treatment performance.
Increased flows, more corrosive waste streams, and stricter effluent limits mean tanks must not only hold volume but also support long-term treatment efficiency, environmental compliance, and operational resilience. Because of this many municipalities and businesses are now looking to upgrade their sewage tanks.
And with capital funding available through programs like the Canada Community-Building Fund, forward-thinking municipalities are prioritizing sewage tank and treatment upgrades that reduce maintenance costs, emissions, and unplanned downtime.
From acidic sludge to aggressive industrial byproducts, sewage storage tanks face some of the most corrosive environments in infrastructure. Greatario’s wastewater storage tank systems are engineered to perform reliably under pressure and in all conditions. Whether that’s at a municipal treatment plant, food processor, or landfill.
Our sewage tanks are constructed from materials known for their chemical resistance and longevity. Glass-fused-to-steel offers unmatched durability for sewage tank applications. It resists corrosion, eliminating the need for repainting, and stands up to decades of exposure to sulfides, acids, and moisture.
Epoxy-coated options are also available for specific industrial or budget-driven projects. Every system is designed to reduce long-term maintenance and preserve structural integrity in high-risk conditions.
Greatario supplies tank systems for every stage of the sewage tank treatment process, from equalization and aeration to sludge holding and biogas recovery. Our modular designs are adaptable to site constraints, scalable for future growth, and compatible with a full range of equipment.
Whether you’re planning new construction or retrofitting an existing plant, our team can help size, configure, and deliver the right tank solution for your wastewater needs.


From equalization to biosolids, our tank systems support every step of the wastewater treatment process. Each solution is engineered to meet regulations, require less maintenance, and fit within your site’s footprint and process design.
Whether you’re planning a new facility or upgrading aging infrastructure, your sewage treatment tank choice has a lot of long-term implications. Greatario’s wastewater storage tank and sewage tank solutions are designed to meet performance targets while supporting sustainability and operational efficiency.
Built to meet or exceed CSA and wastewater treatment compliance standards
A wastewater storage tank is used to hold sewage, process water, or sludge before, during, or after treatment. Common applications include equalization, clarifiers, sludge holding, and digesters.
A sewage tank is typically part of a larger municipal or industrial treatment system, designed for flow management, treatment, or temporary storage. A septic tank is a small, self-contained treatment unit used in residential or remote areas
Glass-fused-to-steel is the most durable option for sewage tank treatment, as it resists corrosion, doesn’t require repainting, and performs well in acidic environments. Epoxy-coated steel is another effective option, depending on the application.
Yes. We supply tanks for a wide range of industrial and environmental uses—including leachate storage, contaminated water holding, and aggressive chemical environments.
