It's lights, camera, and plenty of action for a City of Tulsa camera crew at work in the sewers.
The city started inspecting sewer lines with a camera tractor four years ago. The camera can travel more than a block in sewer lines to document cracks or leaks.
The goal is to find little problems before they cause a backup. Ralph Parker, Supervisor: "The old way was to wait until the sewer backed up or the ground caved in and you knew you had a problem, but now we can easily schedule repairs 6 months to a year ahead."
The problems aren't always big ones. Sometimes the occasional mouse pops into view, but more often it's tree roots or a greasy buildup that causes the problem.
