The Full Line


The FloGard +Plus® is a catch basin insert that provides physical screening of pollutants such as gross solids, trash and debris using a filter fabric basket for removal of petroleum hydrocarbons using sorbent pouches. It is ideally suited for removal of primary pollutants from paved surfaces in commercial and residential areas.

Available in a wide variety of sizes and configurations, the FloGard® can be incorporated in most industry-standard flat-grated and combination drainage inlets by suspending the device from the catch basin frame underneath the grate. The FloGard® insert has a shallow profile, contains a high-flow bypass and is ideal for applications where water needs to be sampled after treatment.

As with any storm water treatment system, the FloGard® requires regular maintenance to prolong the life of the system. Routine maintenance is accomplished by removing accumulated pollutants from the filter basket by hand or by using a vacuum truck and replacing the sorbent pouches. Frequency of maintenance depends on the conditions of the site and performance of the system.

FLOGARD Nettech™


The revolutionary Flogard NetTech™ gross pollutant trap (GPT) system combines a marine-grade, stainless-steel pipe extension with a heavy-duty, UV-stabilized polyethylene net.

The pipe extension incorporates a unique mechanism that allows the net to release in the event it becomes fouled with intercepted debris. The net component automatically detaches and then chokes off on a short tether, allowing the pipe to flow normally.

The versatile system can be customized to suit various flow rates, volumes of debris or retrofit applications.
