The I/I Issue: What’s The Big Deal?

In our first post of this series, we defined inflow and infiltration, or I/I. In this post, we’ll explore the reasons it’s a huge problem in wastewater management. The reason I/I presents huge challenges for municipalities stems from four basic issues: Upstream – Pipeline Capacity: Conveyance system pipeline capacities being overwhelmed and causing sanitary sewer […]
