STORMSURGE® Access Assembly

A safer solution for storm surge events

In areas with flash-flooding or tidal concerns, manhole covers can become an unexpected concern for water systems and the general public. In the event of a major storm surge, the underground water pressure can be so powerful that it can force a cast iron manhole cover open and dislodge it during the event. This creates a hazard for both motorists and pedestrians, and it can leave an empty hole where the manhole cover once was.

EJ has developed a manhole access assembly to solve this problem. During a storm surge or backflow event, the cover is allowed to lift up to 16 degrees, enabling water to flow out and relieve the pressure. The locking arm and hinge restrain the cover, and allow it to return to the seat.
