A major rain or tidal event can overload your storm/sewer systems, which can dislodge manhole covers. This creates a hazard for both motorists and pedestrians and a serious concern for municipalities. The video below shows underground water pressure powerful enough to remove the standard manhole cover.
EJ has developed a manhole access assembly specifically designed to solve this problem. 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.
Cover permanently attached to frame
Safety catch at 90 degrees to prevent unintended closure
Patented design features
Made in the USA
Solid or vented covers
Custom logo covers
Special lettered covers
Security bolt for controlled access and theft deterrence

As the water pressure increases, the STORMSURGE® Access Assembly can lift up to 16 degrees, enabling water to flow out and relieve the pressure. The cover remains attached and properly seats itself after the event.
