Since 2011, the Massachusetts Water Resources Authority (MWRA) had been experiencing liner failures which were identified when a large piece of plastic liner was found at the intake screens of one of the terminal facilities. Subsequent manned entry and CCTV investigations determined that the sections were experiencing significant deterioration of the various lining technologies.
To remedy the on-going problems, the New England-based Ted Berry Company was retained as a specialty subcontractor to complete the critical manned entry inspection, core sampling, sounding, and 3D multi-sensor inspection of the entire length of these sewer segments. The scope of work required manned entry with sounding and core sample collection, which necessitated a significant work plan for health and safety.
With several technologies available to provide multi-sensor inspections for large diameter active sewer segments, the Ted Berry Company evaluated the options and selected the CUES SolidFX Multi Sensor Inspection (MSI) Platform System equipped with the side scanning Digital Universal Camera (DUC), LiDAR and digital Sonar.
