SUI was retained by the Village of Rye Brook (Village) to clean and CCTV inspect 10,000 feet of sanitary sewer conveyance piping, perform 50,000 feet of smoke testing, and inspect 236 manholes in support of an infiltration and inflow (I&I) investigation of a portion of the Village’s wastewater infrastructure.
Although the project specifications did not require the use of a manhole scanner to accomplish the manhole inspections, SUI elected to utilize a CleverScan manhole scanner to capture a 360 degree view of the interior of each manhole in lieu of a digital camera or video recorder mounted on a pole and advanced down each manhole.
The Clever Scan device was situated over each manhole opening and advanced down the interior of the manhole while capturing colored digital photographs and laser measurements. Once the scan was complete, the image was viewed on a laptop computer to verify the quality of the imagery. If required, the CleverScan was deployed for a second to re-capture colored imagery.
Each scan was accomplished in under five minutes and on average, scan data was collected on 50 manholes in an eight hour day.
In an office environment, each scan was imported into WinCanVX pipeline inspection software for subsequent defect coding in accordance with NASSCO MACP, Level 2, protocol. A manhole inspection report was generated in WinCanVX and final deliverables included the manhole inspection report, scan files, and digital photographs.
Utilizing the CleverScan device greatly reduced the amount of time required at each manhole, which reduced the exposure of field technicians and vehicular traffic, and provided high definition three-dimensional imagery of the manhole interior. It is anticipated that the field time was reduced by 60% compared to conventional manhole inspection devices (e.g. digital cameras or video recorders) while providing a higher quality deliverable.
