If you are trying to meet the increasing demands for infrastructure inspection with the same old workﬂows and technology, you’re ﬁghting a losing battle. The evolving challenges of sewer inspection require adapting new technologies and methodologies to gain greater efficiencies and better data. Doing so can allow inspectors to prioritize system-wide which lines need the most attention, and to shorten the interval it takes to perform a complete system assessment.
CCTV crawlers gather the most detailed information from a pipe, allowing an operator to pan, tilt and zoom in on pipe features. They are the most commonly used inspection tool in our industry, and the most detailed method for inspecting the internal condition of a sewer. However, they are also the most time-consuming and labor-intensive to operate.
While CCTV crawler inspection is an essential tool in any condition assessment program, many lines don’t need the level of scrutiny a crawler offers. Rapid assessment tools like zoom cameras and video nozzles are ideal front-line tools for screening out such lines. If municipalities incorporate these tools into a three-phase approach to inspection, they can save signiﬁcant time and money, and maintain more updated information about pipe condition.
