​Attendees at this presentation will learn about how the FELL (Focused Electrode Leak Locating) technology from Electro Scan is being used to more accurately assess both existing and rehabilitated sewer pipes. More specifically, attendees will gain a deeper understanding of:
​

1. New recommended standards for certifying and accepting Cured-In-Place Pipe (CIPP) lining and Point Repairs – using Electro Scanning Inspection to find and measure leaks commonly missed by Closed Circuit Television (CCTV) Inspection. Additionally
   a. How Municipal Agencies can measure CIPP effectiveness (“water tightness”) in Gallons Per Minute
   b. How to specify FELL to certify rehabilitation projects, including allowable Leakage Rates
2. New guidelines for conducting Sanitary Sewer Evaluation Studies (SSES) – using Electro Scanning Inspection to prioritize critical sewers by automatically knowing the difference between superficial surface cracking inside a pipe, compared to the identification and measurement of cracks that go completely through a pipe or joint.
3. An overview of the technology, its key components, major EPA benchmark testing, and reporting.
4. How Electro Scanning Inspection equipment can be easily added to an agency’s existing CCTV truck – able switch from CCTV to Electro Scanning, and back, in the field.
5. Case studies and practical applications on Sewer Main Assessment and Sewer Lateral Assessment projects, comparing CCTV with Electro Scanning Inspection.
