Stormwater infrastructure rated by public works departments across Ontario and British Columbia.

City of Hamilton Public Works 2024 Annual Review

“The StormVault Retention System reduced peak discharge by 42% during the July 2024 100-year storm event. Sediment loading downstream dropped below the provincial target of 25 mg/L. We have specified this system for three additional catchment projects.”

Region of Peel — Stormwater Management Q3 Compliance Report

“BioSwale Edge Filter Strips installed along Hurontario Street achieved 88% TSS removal and 72% phosphorus reduction in the first six months of operation. Maintenance costs were 30% lower than the conventional swale alternative.”

Metro Vancouver — Drainage Operations Pilot Program Results

“HydroGuard Catch Basin Inserts retrofitted to 48 inlets in the Still Creek watershed captured 340 kg of debris and 18 L of hydrocarbons in Q2 2024. Bypass weir functioned as designed during the October atmospheric river event.”

Ontario Ministry of the Environment Compliance Audit 2024

“All three RavenousCreatures product lines meet or exceed the effluent quality criteria outlined in the Ontario Water Resources Act. No exceedances were recorded during the 12-month audit cycle.”
