Tracking and Solving Inflow and Infiltration (I&I) Challenges | WEFTEC SERIES | EP 7

In this episode of Engineers for Communities, host Michael Groselle welcomes Mark Serres from Utility Systems Science and Software (US3). They discuss approaches to identifying, tracking and resolving inflow and infiltration (I&I) issues in wastewater collection systems.

The conversation runs from practical fixes to advanced data tools. It is aimed at communities that want their systems to run more efficiently and cost less.

It also covers why "boots on the ground" knowledge matters, and how working with city technicians leads to more efficient problem solving.

In this episode

• The basics of I&I: what it is, how groundwater infiltration and stormwater inflow happen, and how they affect collection systems and treatment plants.
• Detection methods such as smoke testing, flow monitoring and visual surveys to find problem areas and judge how severe they are.
• Using dry and wet weather flow data to quantify I&I, and how US3 brings in Advanced Metering Infrastructure (AMI) data for faster, more precise diagnosis.
• How flow monitoring combined with temperature, rain gauge and AMI data points to common sources such as school systems, golf courses and improperly connected storm drains.
• Case studies where targeted fixes removed major I&I sources and avoided costly treatment plant upgrades.
