We deployed StormCAD Pro Suite on a 12-km trunk sewer model for the Region of Peel. The first month was spent calibrating the rainfall-runoff parameters against three years of historical flow data. The software handled the 100-year event simulation without crashing, and the hydraulic grade line output matched our field measurements within 4%. The automated report generator saved roughly 18 hours of drafting for the Conservation Authority submission. The only friction was the initial GIS import—the projection mismatch took two support tickets to resolve. Overall, the tool performs as specified for municipal drainage work.
The project exists to deliver defensible hydraulic models and flood control designs that meet the specific regulatory requirements of Canadian Conservation Authorities. Every principle below is a constraint, not a slogan.
Hydraulic grade line certainty Each model must produce a verified HGL for the 100-year event. No extrapolation beyond the calibrated range is accepted in regulatory submissions.
Conservation Authority alignment All stormwater management plans follow the technical guidelines published by the local Conservation Authority. Deviations require written justification and peer review.
Return period consistency Design storms are drawn from the most recent IDF curves for the watershed. Historical data sets older than 10 years are flagged for update before use.
Post-construction monitoring Every flood control system includes a monitoring plan with flow gauges and stage sensors. Data collection intervals are defined in the permit conditions.
