Engineered detention, filtration, and conveyance systems designed to meet provincial Clean Water Act discharge standards. Our modular solutions reduce TSS loads by 80–90% while attenuating peak flows to pre-development levels.
Common questions about our engineered stormwater infrastructure, regulatory alignment, and field performance under Canadian provincial standards.
The precast concrete vault sections are engineered for a minimum 75-year service life under normal loading and flow conditions. All units are manufactured to CSA A23.1 and include HDPE liner options for groundwater protection. The integrated oil-grit separator requires periodic inspection but no structural replacement within the design horizon.
Yes. The BioSwale Edge Filter Strips are designed in accordance with the Ontario LID Stormwater Management Planning and Design Guide. The layered soil media achieves 70% phosphorus reduction and 90% TSS removal, meeting the provincial targets for new development and redevelopment projects. Each 3m segment is pre-vegetated and ready for installation.
Quarterly cartridge swaps are recommended for typical urban catchments. The integrated sight tube allows visual confirmation of media saturation without removing the unit. Each cartridge adsorbs up to 12L of oil and captures 82% of particles larger than 50 microns. A bypass weir prevents flooding during extreme events if maintenance is delayed.
Yes. The HydroGuard Catch Basin Insert is specifically designed for retrofits. It fits standard 600mm x 600mm inlets with a stainless steel frame and drop-in cartridge system. No excavation or structural modification is required. The BioSwale Edge Filter Strips can also be installed along existing road shoulders with only a skid-steer for mobilization.
The StormVault Retention System provides 85% total suspended solids removal under design flow conditions. The built-in sediment control and oil-grit separator handle peak flows up to 28 m³/s while attenuating discharge to pre-development levels. Performance is verified through factory testing per CSA A23.1 and field monitoring protocols.
All RavenousCreatures stormwater products are manufactured and tested to align with provincial Clean Water Acts and the Canadian Environmental Protection Act, 1999. Material specifications, effluent quality targets, and installation procedures are documented in our compliance package available upon request for municipal and consulting engineers.
How the service works
Comparative analysis
All designs reference the applicable provincial Clean Water Act and municipal stormwater management bylaws. Pre-certified treatment trains eliminate the need for post-construction re-engineering.
Third-party testing under ASTM and CSA protocols confirms TSS removal rates between 82% and 90% and phosphorus reduction up to 70%. Performance curves are published for each product line.
Modular precast components reduce on-site labour and inspection time. Replacement cartridges and media segments are standardized across projects, minimizing inventory and training overhead.
Retrofit inserts and swale segments fit standard inlet dimensions and roadside geometries without excavation beyond the existing footprint. This reduces disruption to traffic and utilities.
Each installation includes a site-specific hydraulic sizing report, maintenance schedule templates, and direct access to the design team for permit submissions and variance requests.
