CCTV Sewer Inspection

The collection and storage of CCTV inspection data in the field is performed by certified operators using current CCTV inspection hardware and software in accordance with the Pipeline Assessment Certification Program (PACP) system approved by the National Association of Sanitary Service Companies (NASSCO).

The field data is checked by competent and certified office personnel for consistency and any deficiencies are resolved either within the software or by revisits by field crews to clarify and obtain any missing data.

Accepted data is used to generate CCTV logs and the videos are stored on DVD media. The data can be converted into the industry standard “sewer.dat” files and processed further and ranked for service and structural defects.

The I&I potential for each inspected pipe segment can be calculated using a combination of defects characterization in conjunction with a database of I&I values.
