Capture and retain stormwater sediment, trash and floatables in a unit that saves site space and adapts to smaller or logistically difficult site locations.
First Defense® is a versatile stormwater separator that works with single and multiple inlet pipes and inlet grates. It is easily maintained from the surface by standard vacuum tanker.
Designed with site flexibility in mind, First Defense® stormwater separator provides versatile capture of sediments, trash and floatables that allows engineers to maximize available site space without compromising stormwater treatment level.
First Defense® works easily with single or multiple inlet pipes and inlet grates, and is independently tested, verified and approved.
The First Defense® reliably treats runoff from impermeable surfaces across a broad range of catchments.
First Defense® also operates successfully as part of a management train alongside other proprietary or natural drainage features, for example as treatment before infiltration.
