Cameras are inserted into a sewer manhole and dispatched up a sanitary (or storm) sewer.

The TV trucks generate a video recording, which can be analyzed at a later date to identify cracks, dislodged pipe joints, locations of house lateral connections, flow conditions and any other sewer characteristics.

This is one of many maintenance programs to ensure that the sanitary sewer system continues to operate effectively and efficiently, and to renew the aging infrastructure.

The sanitary sewer system is a key piece of infrastructure consisting of approximately 465 miles of sewer pipes and 13 lift stations.
