Case History
Electro-Scan Adds a New Dimension to Sewer Leak Detection
Case History - City of Redding CA

Electro-Scan pin points pipe defects that were large sources of infilration. These defects were not detected by conventional sewer evaluation tools


Test Data Comparison
Comparison of Electro-Scan, joint air pressure testing and CCTV
Electro-Scan is as good as joint air pressure testing and 20 times more effective than CCTV inspection.

Electro-Scan and CCTV
TV tape of 8" VCP sewer pipe and Electro-Scan data compared side by side
Electro-Scan is at least as good as CCTV at half the cost and time
