Who Knows What's Missing
Canada's water and wastewater sector is one of the most regulated and technically demanding in the country. The only study resources available were dense government manuals, expensive in-person courses built on decade-old slides, and American exam apps that referenced the wrong regulations entirely. Echelon was built to fix that.
Every question is mapped to each province's regulatory framework. Every visual module lets you see and interact with real treatment processes — not just read about them.
The AI Tutor is trained on Canadian regulatory content and can explain why a CT value matters, how to calculate a chlorine dose for a specific flow rate, or what provincial regulations require for turbidity monitoring.
Ay Bello, an Environmental Engineer (EIT) and Master's student in Digital Transformation at the University of Ottawa, identified a clear gap — operators were studying for technically demanding exams with resources that hadn't evolved in decades.
Interactive SVG process diagrams, an adaptive practice engine, an AI tutor with confidence scoring and pattern detection, and a career path map based on real 2025 OCWA data.
475 OIT practice questions, 10 study modules, process diagrams for drinking water and wastewater, pumping systems, lab and sampling, and a formula reference — launching in Ontario with BC and Alberta coming next.
Every question, regulation, and process description is specific to each province's framework. No American content repurposed for Canadian exams.
The AI Tutor explains the why behind every answer — CT values, dosing calculations, turbidity monitoring requirements.
From OIT through Class 4. Content that grows with your career and supports every certification level.
Coming Soon to BC & Alberta
Echelon is expanding beyond Ontario. Province-specific question banks, regulatory content, and AI tutoring tailored to EOCP and Alberta EPA certification exams are in development.
