Rain Guardian

Rain Guardian pretreatment chambers provide a stable inlet and effective pretreatment for bioretention BMPs. Rain Guardian chambers capture 60-90% of sediment and gross solids at the inlet and can be cleaned out with nothing more than a flat-nosed shovel.  Rain Guardian chambers extend the effective life of bioretention BMPs by simplifying maintenance. Our chambers for residential, commercial, and under-sidewalk applications are easy to install in both new and existing BMPs.
