 INTEGRATED SENSOR SURVEYS

OUR HOLISTIC DATA COLLECTION TECHNOLOGY PROVIDES NEW AND
UNRIVALLED DEFINITION OF FIXED ASSETS.

Overall, while CCTV is a useful tool for sewer inspections, we believe that it should not be relied on as the sole method of inspection. Combining CCTV with other inspection methods, such as sonar or laser surveys, can provide a more comprehensive understanding of the condition of the sewer line and help to identify issues that may be missed with CCTV alone.

PROACTIVE AND COST EFFECTIVE SURVEYS

Although we can survey pipes as small as 6” (150 mm), we
specialize in Large Diameter Pipes from 18” (450 mm) and up.

Our integrated-sensor data collection technology can provide you with new and unrivalled definition of your fixed assets.

Let us help you with your challenging inspection/survey problems, We have over 30 years of experience and our design team can assist you. 

We have designed & built innovative robotic systems as well as software for specific survey challenges. We transform data into useful information that can be uploaded into Cad type programs. 

We collect video & xyz point cloud data above and below water using digital video cameras, time of flight lasers and digital sonars.

Manholes

  • High resolution 12 mega pixel video, see small details clearly
  • Time of Flight 3D laser, accuracy to 5 mm with a dense point-cloud
  • RTK GPS 2 cm elevation accuracy, calculate gradients between Maintenance Holes
  • GIS ready data, install ready

Large Diameter Sewers – our lighting makes the difference

  • Integrated sensor surveys
  • High resolution images
  • High quality frame grabs
  • Long range surveys (up to 6,000 ft.)
  • High output LED lights for clarity

Siphons – Skid mounted or Siphon Float

  • Long range possible
  • Shows sediment buildup
  • Pipe diameter
  • Pipe shape
  • Air pockets

Culverts

  • Pontoon Float
  • Tractor
  • ROV (Remotely Operated Vehicle)
  • High resolution camera
  • Time of Flight laser

Typical Obstacles to Culvert Inspection

  • Little or no water flow to establish a towline
  • Dry to submerged pipe conditions
  • Flap gates, other gate structures
  • Permanent grating at access
  • Corrugated pipe damage
  • Years of debris buildup
  • Submerged access
  • GIS errors

Outfalls

  • Tractor
  • ROV (Remotely Operated Vehicle)
  • High resolution camera
  • Profiling sonar

River Crossing Surveys Gas, water, and cables river crossings present special hazards.

  • Bathymetric surveys
  • Sub-bottom profiling
  • Side-scan sonar surveys
  • Depth of burial surveys
  • Identify problem areas
  • Identify anchor drags near pipe
  • Identify areas of scour
  • Identify bare pipe
  • Flood event sediment tracking
  • ROV Inspections
  • Diver Intervention

Treatment Plants

  • Pontoon Float
  • Tractor
  • ROV (Remotely Operated Vehicle)
  • High resolution camera
  • Time of Flight laser

Pipe Inspection & Acceptance Testing

Our pipeline pre-acceptance survey offers a range of solutions to
inspect the pipeline, depending on the specification.
  • High Resolution CCTV.
  • Time of Flight (ToF) laser survey (5 – 10 mm accuracy)
  • Pipe Deformation/Ovality Testing
  • Underground Pipe Mapping

Underground Pipe Mapping.

Our 3D mapping systems are used for high accuracy positioning of  underground sewer/pipe positioning. We can combine CCTV as well as pipe ovality in one survey.

Egg Shape Pipes

Specialty builds for challenging areas.

For instance, we have conducted CCTV, Sonar and Laser surveys in many miles of Egg Shape pipe.
