A major rain event can overload your storm/sewer systems, which can dislodge manhole covers. This creates a hazard for both motorists and pedestrians.
The STORMSURGE Access Assembly allows water to flow during a storm surge or backflow event. The cover is capable of lifting up to 16°, enabling water to flow out and relieve the pressure. The locking arm and hinge restrain the cover and allow it to properly seat itself after the event.
