Toronto Startup AquaVolt Converts Factory Wastewater Into Drinking Water, Electricity

Walk into AquaVolt's compact operations hub on King Street West, sandwiched between a craft brewery and a design studio, and you'll find something that feels deceptively simple: a modular electrochemical system no larger than a refrigerator that's quietly reshaping how Toronto's industrial sector thinks about waste management and energy recovery.

Founded in 2023 by a trio of engineers who met at the University of Toronto's Engineered Resilience Lab, AquaVolt has developed a proprietary membrane technology that simultaneously purifies industrial wastewater and generates electricity through ionic separation-essentially killing two birds with one stone in a sector where both water treatment and energy costs are astronomical.

"Manufacturing facilities in the Greater Toronto Area spend roughly $1.2 million annually on wastewater treatment alone," explains the company's technical documentation. "AquaVolt reduces that by 70 percent while generating enough power to offset about 40 percent of the system's operational costs."

The numbers caught the attention of Waterfront Toronto and the provincial Ministry of Energy. In May, AquaVolt secured $4.8 million in Series A funding-a round led by Toronto-based venture firm Sustainable Ventures Partners-with backing from the Toronto Innovation Foundation. Within weeks, the company announced pilots at two major automotive parts manufacturers in the Greater Toronto Area, expected to go live by Q3 2026.

What makes this innovation particularly resonant for Toronto is timing and location. The city has committed to net-zero emissions by 2040, and manufacturing-still a pillar of the regional economy despite decades of decline-remains a major energy consumer. AquaVolt's modular approach means small and mid-size producers can adopt the technology without massive capital expenditure or facility overhauls.

The company is also leaning into Toronto's talent ecosystem. They've hired engineers from Magna International's Toronto research center and partnered with Ryerson University's Chang School on workforce training. A second office opens this fall in Liberty Village, where they'll house their growing hardware testing lab.

"The clean energy conversation often focuses on solar panels and wind farms," one industry analyst noted in recent remarks at the Toronto Sustainability Innovation Forum. "But the real opportunity is in industrial process optimization-which is exactly where companies like AquaVolt are creating immediate impact."

AquaVolt isn't household name territory yet. But in the increasingly competitive global race to decarbonize heavy industry, it's the kind of overlooked player worth watching.
