Manhole Events

Evaluation of mitigation options and monitoring systems

This research focuses on understanding the causes of manhole events, determining methods to identify precursors to such events, and assessing various event mitigation systems. Expected results can inform selection of monitoring systems to identify manhole event precursors.

The video illustrates the potential energies that can be developed and released during a manhole event.

This video depicts testing associated with various manhole lid retention systems.
