CES uses advanced flow meter equipment to monitor sewer flow during both dry and wet weather conditions. Dry weather data establishes baseline flow levels, while wet weather data highlights the impact of rain events on I/I levels. 

We then compare wet and dry weather data to quantify I/I in specific sub-basins, allowing our clients to target problem areas accurately, stay compliant, and assess whether a system can accommodate new development.

Wet Weather Flow Response - Average Flow = Inflow & Infiltration (I/I)

Our expert technicians analyze flow monitoring data to identify sub-basins with the highest levels of I/I and recommend focused SSES inspections that address the most critical areas first. CES deliverables include actionable reports with detailed findings, including I/I rates, system weaknesses, and recommendations for rehabilitation.
