Using Real-Time Data Logging to Detect Unsafe Conditions and Safeguard Against Manhole Events

April 11, 2017

Thousands of manhole events occur in North America each year and the frequency of events appear to be rising as electrical, gas and water infrastructure ages. Actively monitoring these spaces in real time and receiving actionable alarms will allow service owners to take action before issues occur. Novinium has spent the last two years developing a real-time low maintenance data logger for use in subterranean confined spaces, which is detailed in the contents of this paper.

PreVent™ Water Control Cover Datasheet

January 1, 2017

Most manhole ventilation solutions fail to prevent higher levels of water and salt from entering the manhole. Secondary cable deterioration produces combustible gases that can lead to a manhole event. The PreVent™ manhole cover is engineered with a set of channels and grooves that divert water, salt, and other debris away from the manhole.

PreVent™ Active Venting Datasheet

January 1, 2017

Utilities rely on vented manhole covers to let combustible gases escape, but these passive solutions are insufficient for maintaining safe manholes. To provide adequate safety for manhole structures, a more active venting solution is required. The PreVent™ solution provides active venting for manholes to keep combustible gases from collecting and potentially causing a manhole event.
