EnviroSafe™ cartridge basins provide ample storage volume for sediment, trash and debris carried in from storm water runoff. A hooded by-pass eliminates the potential for flooding during extreme storms, while still retaining floatables captured during the event. EnviroSafe™ also keeps the captured material dry simplifying service and reducing disposal costs.

EnviroSafe™ single and double basins are easy to install. The cartridge basins can be fitted to rectangular grate widths from 21 to 30 inches and lengths from 27 to 38 inches. The round basin units fit grate diameters from 24 to 30 inches. Rectangular double cartridge basins will fit grate widths from 21 to 36 inches and lengths from 39 to 52 inches.

Different mounting flange assemblies are available for a variety of grate styles. Mounting flange designs incorporate an easy adjustment mechanism enabling up to 4 inches in each direction. All combo curb flange models include a rear deflector for redirecting flow filtering.
