Penstock Condition Assessment peace of mind through state of the art technology
SewerVUE Technology’s multi-sensor inspection platforms can be deployed in pipes of different sizes and compositions, and definitely are not limited to just sewers. SewerVUE has extensive experience with inspecting penstocks as well. Using multiple state of the art surveying technologies, SewerVUE can deliver accurate condition assessments, fast.
Our versatile multi-sensor inspection system can be deployed on an MPIS Float, or SewerVUE’s remotely operated Surveyor robot, depending on the flow inside the pipe. These platforms have a range of 2000 meters or 6000ft, reducing the dependence on convenient access. As expected, SewerVUE has experience inspecting pipes in remote mountainous location. These surveying techniques allow for long stretches of pipe to be assessed while eliminating the potential dangers of man entry.
SewerVUE employs four sensors to collect data: high-definition CCTV cameras, millimeter-accurate LiDAR, sonar, and SewerVUE’s own Pipe Penetrating Radar (PPR) technology. Data from any combination of the four sensors can be aggregated into a unique 4-in-1 viewer using our proprietary software. The data provided by SewerVUE will detail the length, width, and depth of any and every defect found inside a penstock. Our methods will deliver accurate, fast, cost-effective results.
SewerVUE Technology was hired to survey 585 meters of pipe at Clayton Falls Penstock in Bella Coola, BC. For this project, the Surveyor robot was used to capture CCTV footage and LiDAR data. Surveying was done over the course of two days. Data was collected from 3 separate pipe sections, using 2 separate deployments each from the same access point. Upon analysis of the data, SewerVUE identified a number of defects in the longest section of pipe, while the other 2 sections came up clean.
The same technology was deployed to inspect two different sizes of pipeline at the Bridge River Generating Site near Lillooet, BC. First, 350 meters of 375mm CSP was surveyed using the high definition CCTV camera. Then, the Surveyor robot was used to gather CCTV and LiDAR data from 250 meters of 600mm pipe. The data collection took just one day, and was done via two deployments from two different sites. The data showed a number of defects across each section of pipe that was surveyed, which allowed the client to make informed decisions about what, if any, maintenance was required.
The Surveyor was also used for a much larger project near Empire, Colorado, to survey over 1600 meters of water diversion reinforced concrete pipe. (RCP) Additionally, SewerVUE surveyed 457 meters of steel and HDPE pipe using the MPIS float. To survey the 1600 meters of RCP, only a single access point was needed. The data was collected through two deployments, one travelling up the pipe, and another travelling down. CCTV, LiDAR, and PPR data was collected, and revealed the pipe to be in overall good condition. In total, SewerVUE surveyed over 2 kilometers of pipe, using two different sensor platforms, and completed the operation in just 3 days.
SewerVUE can tackle big jobs in some of the toughest places on Earth, and get actionable data quickly. Our methods are both accurate and cost-effective. By using remotely operated vehicles to gather data, these methods also eliminate the hazards of man entry surveying methods. To discuss how SewerVUE can meet your specific needs, contact us today!
