Talking Under Water Episode 43: Small Systems Trends

Aug. 20, 2021

In this month’s episode, the podcast hosts discuss infrastructure news and extreme weather events, plus they share an interview on small systems trends

In this month’s episode of Talking Under Water, hosts Lauren Del Ciello, Katie Johns and Bob Crossen touch on recent news from the US Water Alliance — another One Water advocate like this podcast — announcing a new CEO. The hosts also cover progress on the U.S. Investment and Jobs Act, following months of bipartisan negotiations between the Biden Administration and a bipartisan group of Senators. Then they dig into a discussion on the relationship between recent increasing extreme weather events and water.

Finally, the interview this month is with Ronit Erlitzki, director of business development and innovation for AdEdge Water Technologies, and RJ Cavagnaro, director of marketing for AdEdge Water Technologies. Crossen spoke with Ronit and RJ about small systems trends in requested treatment tech, packaged systems and contaminants of most concern.
