We take proactive measures to improve performance levels our collection system. Televising is the most effective method to inspect the internal condition of a sewer. The main purpose of these inspections is to determine the condition of the pipe and if any blockages are present that may require cleaning, replacement or a repair may be necessary. The inspections also help the city detect if there are any cross connections between sewers and help maintain compliance with state and federal regulations.
Specially made waterproof cameras allow for a visual inspection of sewer lines and laterals that are underground. Using a camera takes the mystery out of what lies beneath. We operate a closed circuit television (CCTV) truck which is equipped with cameras mounted on a robot crawler which relays live footage from within the sewer to a monitor in the truck via CCTV. The crawler can be placed down a manhole and remotely driven from within the truck down the sewer to the next manhole. The operators can examine the entire length of a sewer line between two manholes. These cameras have pan and tilt capabilities which allow the operator to move the camera in all directions to obtain a thorough picture of the entire sewer line. This also allows for service connections to be located and documented. A footage counter is connected to the camera, enabling the operator to note the exact location of any service connections or problems. The camera also transmits video back to the CCTV truck that can be recorded for future use. Documentation of inspection is critical to a successful operation and maintenance (O & M) program.
