Stormwater Management

Stormwater detention and infiltration systems capture and store stormwater in underground tanks or chambers, where it is detained and then recharged to the ground or discharged to a collection system. High Density Polyethylene (HDPE) detention tanks are an economical solution for stormwater management.

The Downstream Defender® is an advanced vortex separator used to treat stormwater runoff in pretreatment or stand-alone applications. Its unique flow-modifying internal components distinguish the Downstream Defender® from conventional and simple swirl separators that typically bypass untreated peak flows to prevent washout of captured pollutants. The Downstream Defender® treats the entire storm with no washout or untreated bypass flows.

The EnviroBasin™ is an entirely new approach to stormwater treatment. This all-in-one device incorporates the revolutionary capture power of the LittaTrap™ inlet filter with additional flow-modifying components that enhance the capture and retention of trash and sediment. Combined into a concrete catch basin, the EnviroBasin™ offers a deeper sump to provide greater sediment storage capacity, efficiently conveys peak stormwater flows without resuspension, and features separate trash storage for easy maintenance, without the need for confined space entry.

The First Defense® High Capacity is an enhanced vortex separator that combines an effective stormwater treatment chamber with an integral peak flow bypass. It efficiently removes total suspended solids (TSS), metals, trash and hydrocarbons from stormwater runoff without washing out previously captured pollutants.

The Hydro-Brake® Vortex Flow Control is a specially designed vortex flow control valve which provides water quantity management for stormwater drainage systems. Its unique vortex flow technology effectively and reliably controls discharge flow across a wide range of operating conditions and applications from small individual plots to large sewer networks.

Stormwater detention and infiltration systems capture and store stormwater in underground tanks or chambers, where it is detained and then recharged to the ground or discharged to a collection system. Polypropylene detention tanks are an economical solution for stormwater management.

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

The SDD3 by NEXT Stormwater Solutions is an enhanced hydrodynamic separator that uses a twin vortex design plus gravitational and centrifugal forces to effectively remove sediment (TSS), floatables, and oil from surface runoff. Removal of other common stormwater runoff pollutants such as N, P, Pb, Cu, and Zn will also occur as they naturally couple themselves to suspended solids. The SDD3 provides increased protection for downstream waterways and processes.

The Up-Flo® Filter is a multi-stage stormwater treatment system that combines pretreatment with fluidized bed filtration technology in one structure for superior filtration rates and media longevity. The Up-Flo Filter optimizes the balance between high treatment performance and total cost of ownership.
