The City of Campbell River monitors storm and sewer pipes using closed circuit television video (CCTV). CCTV cameras offer an environmentally friendly, cost-effective inspection method that can be configured to serve a number of different situations, making them a highly versatile tool.
CCTV allows the City to complete important tasks within the pipes. Staff complete routine inspections of the Cities’ assets underground. This condition assessment allows planners to target repair and replacement budget accurately. They also complete inspections of trouble spots. Occasionally, damage or blockages occur that cause issues with the storm or sanitary collection systems. CCTV can assist us in determining the appropriate course of action.
How it Works
A dedicated CCTV truck operates year round to assess the condition of our pipes. The truck has the ability to launch one of two different sized tractors. These self-propelled platforms carry the camera down the pipe. With this equipment, we have the ability to inspect 150 mm (6 inch) to 900 mm (36 inch) pipes. In addition, we are able to launch a push style camera from this tractor inside the pipe. This can inspect service connections as small as 100 mm (4 inch), from the main line to the property line of homes and/or businesses.
Video data collected is assessed in real-time by a qualified operator. This assessment is stored directly onto the video, giving a real-time description and visual of the asset. Some typical issues we see are settling of the pipes causing sags or low points, cracks, breaks or root intrusion into the pipes. The data is collected and analyzed, then repairs and maintenance are prioritized to ensure the most cost-effective and efficient solutions are implemented.
What to Expect
The operation of the CCTV truck is a low impact process. Most times, businesses and homeowners will be unaware that the pipes in their neighbourhood have been inspected. Residents do not have to prepare for CCTV inspections. We ask they drive safely around the CCTV truck, as this can cause minor traffic disruptions. Every attempt is made by City staff to minimize the impact of traffic flow at all times.
