Terra employs several technologies to provide clients with in depth and accurate data of their waste water collection systems and other material conveyance pipelines. Terra utilizes closed-circuit color TV units to carefully inspect each sewer section to ensure that all damage or defects are properly logged, and we rely on NASSCO certified PACP reporting software for defect coding.

Coupled with an experienced and accredited team, Terra is the most professional service provider for your sewer studies.  Solutions include:

  • Terra provides laser profiling of sewers and pipelines with diameters between 6” and 60”
  • Allows the crew to collect data reflecting pipe capacity, ovality/deformation, corrosion and other abnormalities
  • Data collected is accurate to within 1 mm, ensuring precise data to aid the client in determining the condition of their pipeline and sewer systems

  • The PANORAMO System is the cutting edge of technology in sewer evaluation.
  • The PANORAMO System utilizes twin 185 degree HD Digital cameras, mounted on the front and rear of the robotic crawler. The cameras capture still photos as the crawler travels through the sewer. The integral software then “stitches” the photos together creating a continuous stream view of the sewer, allowing for the most in depth analysis of sewer conditions in the OFFICE and not in the field. 
  • The flexibility of this technology allows for a wide range of reporting options to fit the client’s needs. 
  • All data collected is downloaded to a NASSCO certified PACP reporting software and is completely compatible with all GIS systems.

  • Using the same PANORAMO technology as the mainline system, the SI incorporates the technology to conduct inspections of manholes and other vertical shafts up to 12 feet in diameter and depths to 500 feet.
  • The PANORAMO technology allows for a full 360 degree view of the manhole and flexibility for the end user to collect snap shots of their choice to populate their assessment reports.
  • In addition to snap shots, the software can create 3D Point Clouds, enabling the end user to measure any feature found in the manhole. As an added value, the 3D Point Cloud can be exported in a DXF format for use in CAD programs.
