CCTV and SONAR Inspection of Trunk Sewer

THE PROBLEM:

After an unrelated procedure was completed in the sewer system construction project near the Trunkline, a municipal crew reported high wastewater flow in one manhole and suspected an unknown blockage. Water levels were too high to enter the area, as the manhole chimney was underwater, so our team performed a sonar inspection to provide our client with valuable data for rehabilitation.

OUR SOLUTION:

Pipe and Plant deployed a specially trained CCTV and sonar inspection team to inspect fully surcharged wastewater lines. The inspection results were sufficient for the client to design specific rehabilitation solutions based on actual field data and conditions.

PROJECT CHALLENGES:
  • High pedestrian traffic work area
WORK ELEMENTS:
  • Prevailing wage work
  • CCTV and sonar
  • Traffic control
