Joshua Dress and Josh Jeffi work in Sewer System Maintenance & Operation, the Sewer District team that monitors and maintains a complex underground system that keeps wastewater flowing to our three treatment plants.  Josh and Josh, with Mike and Donna, lift the lid and descend deep into the topic of sewers, including the history of sewers in the region, how they work, what it takes to keep things flowing, and even some of the craziest things they've seen underground.
