Stormwater Management Solutions

CULTEC® Stormwater Chambers provide a cost-effective underground solution for stormwater detention and infiltration. Their open-bottom, corrugated plastic design promotes natural groundwater recharge, reduces runoff, and helps improve water quality while preserving valuable surface space.

HydroStor Stormwater Chambers are high-performance polypropylene systems designed for underground stormwater detention and infiltration. Durable, corrosion resistant, and custom engineered, they provide reliable stormwater management while meeting or exceeding ASTM and CSA standards.

Corrugated Steel Pipe (CSP) detention and infiltration systems provide a cost-effective, customizable solution for stormwater management. Available with full or partial perforations for infiltration and groundwater recharge, or non-perforated for controlled flow applications, CSP systems are engineered for long-term performance and easy maintenance.

The EnviroBasin™ is an all-in-one stormwater treatment system that combines the LittaTrap™ inlet filter with enhanced flow control to improve trash and sediment capture. Its deep sump increases sediment storage, efficiently handles peak stormwater flows without resuspension, and features separate trash storage for easy maintenance without confined space entry.

The LittaTrap™ mesh basket is designed to capture and retain plastic and other gross pollutants over 5mm. The basket has high hydraulic conductivity, is lightweight yet structurally robust, and is designed with engineered inert plastic for a 25-year lifespan.

The SDD3 is an enhanced hydrodynamic separator that uses a twin vortex design to remove sediment (TSS), floatables, oil, and other stormwater pollutants from surface runoff. By improving water quality and protecting downstream waterways, the SDD3 provides an effective solution for stormwater treatment.

The Slotted Drain is a durable galvanized steel surface drainage system designed to efficiently collect runoff from paved surfaces. Available with three grate options, it is compatible with CSP, PVC, and HDPE pipe, offers easy maintenance, resists freeze/thaw cycles, and performs well in flat, steep, or shallow-burial applications.

The Downstream Defender® is an advanced vortex separator that removes sediment, floatables, and other pollutants from stormwater runoff. Its unique flow-control design treats the entire storm without pollutant washout or untreated bypass, delivering high treatment efficiency in a compact footprint.
