Seeing Inside a Sewer Line

The Sewer Department has a special TV camera that is used to see inside a sewer line so blockages and cracks can be more easily identified. Approximately 20,000 linear feet of sewer lines are TV inspected annually. The Department was able to identify 2 significant blockages and several cracked pipes that otherwise would have gone undetected.
