CB Shield is a new and innovative way to increase water quality right at the source! The CB shield inserts into any new or existing Catch Basin Manhole, to increase the capture of suspended solids. It shields the sediment and grit found in the sump of the catchbasin from being washed out.
The top slope of the shield deflects the flow of water to the back wall of the catchbasin while the grates allow water to flow over the top and exit the outlet pipe. Sediment falls between the slots.
