Tracking and Solving Inflow and Infiltration (I&I) Challenges | WEFTEC SERIES 2 | EP 7

In this episode of Engineers for Communities, host Michael Groselle welcomes Mark Serres from Utility Systems Science and Software (US3) to discuss innovative approaches to identifying, tracking, and resolving inflow and infiltration (I&I) issues in wastewater collection systems. From practical solutions to leveraging advanced data technologies, this conversation offers valuable insights for communities looking to enhance system efficiency and reduce costs.

↳ Understand the basics of I&I: what it is, how groundwater infiltration and stormwater inflow occur, and their impact on collection systems and treatment plants.

↳ Discover practical detection techniques like smoke testing, flow monitoring, and visual surveys to pinpoint problem areas and assess their severity.

↳ Learn about leveraging dry and wet weather flow data to quantify I&I and how US3 integrates Advanced Metering Infrastructure (AMI) data for faster, more precise diagnostics.

↳ Explore how flow monitoring combined with temperature, rain gauge, and AMI data helps identify common offenders such as school systems, golf courses, and improperly connected storm drains.

↳ Hear case studies of rapid, cost-effective solutions where targeted fixes eliminated major I&I contributors, avoiding costly treatment plant upgrades.

↳ Gain insights into advanced calibration techniques, 3D camera inspections, and LiDAR technology for accurate data collection and manhole assessments.

↳ Understand the importance of “boots on the ground” contextual knowledge in collaboration with city technicians for efficient problem-solving.

This episode is a must-watch for anyone seeking actionable strategies to improve wastewater system management while minimizing unnecessary expenses. Learn how fresh perspectives, innovative technology, and collaboration can lead to quick, impactful results for your community or development project.
