For the past 10 to 15 years, wastewater treatment operators have faced increased clogging issues related to baby wipes, disposable diapers, rags, and other foreign debris. At the same time, the use of low-flow toilets has increased the solids concentration of sewage flow. This discussion with Brad Jernigan and Christina Foster from Pentair addresses differences between how grinder pumps (low flow/high head) and chopper pumps (higher flow/lower head) can benefit that situation. They also compare the advantages of how axial-cutter design vs. radial-cutter design can aid in shredding large debris, bit by bit, without sucking it into the body of the pump where it can clog and shut down the unit.
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.
