Fixing an Aging Infrastructure with Minimal Disruption
Coping with service or repairs to aging pipeline infrastructure without disrupting customers is always a challenge. Chris Vazzana of Hydra-Stop has a better idea that includes the use of insertion valves, which enable water utilities to install a permanent valve into a live water main without ever shutting down the line. His discussion with the Water Talk moderators at WEFTEC 2019 details how the initial perception of insertion valves as a temporary measure is no longer true, and how these time-saving devices are now permanent assets that have passed AWWA testing, including burst testing and 500-cycle testing. Chris also describes the company’s newest 24” insertion valve, with an anecdote about saving a utility and 10,000 of its customers from a disruptive service shutdown.
