Products
-
Downstream Defender ®
The Downstream Defender® is an advanced vortex separator available for the removal of sediment, oil and floatables from stormwater runoff. The Downstream Defender is proven to be more efficient than other structural treatment devices in as little as ½ the footprint and is the only separator with internal components proven to prevent pollutant washout.
-
Up-Flo Filter ®
The Up-Flo Filter® is the most efficient high-rate stormwater filtration technology available for the removal of trash, sediments, nutrients, metals and hydrocarbons from stormwater runoff. As the industry’s only fluidized bed upflow filtration technology, the Up-Flo Filter® provides a higher level of treatment, a higher rate of filtration, longer life of filter media and a longer maintenance cycle than other filter systems.
-
First Defense®
The First Defense® is an enhanced vortex separator that provides stormwater treatment in a surface inlet device. The integral bypass and large pipe sizes convey a wide range of flows without risk of washout and surface flooding.
-
Stormbloc®
Stormbloc® stormwater detention and infiltration systems provide site planners with many design options for low impact, LEED® or ultra-urban development projects. With over 95% void ratio, Stormbloc® requires a less disruptive, smaller footprint than pipe and arch chamber systems.
-
Reg-U-Flo®
The Reg-U-Flo® Vortex Valve provides superior hydraulic performance over conventional flow controls. Its unique features reduce the chance of blockages and reduce runoff detention volumes by up to 30%.
