Last year, Fort Worth, Texas completed the fourth year of its Fort Worth Interceptor Condition Assessment Program (ICAP), an initiative designed to inspect the entirety of the city’s large-diameter sanitary sewer lines and determine their condition in order to make repairs. By the end of 2014, the city had managed to inspect to about sixty percent of its pipes.
CCTV equipment is typically the technology used to inspect pipes, usually after the pipe has been cleaned as it makes defects much easier to spot. The ICAP takes an entirely different approach as inspections are made before the pipes are cleaned using 3D laser technology. Instead of standard CCTV video, a fusion of sonar, laser profiling, and HD video allows better evaluation of a wall’s corrosion versus conventional CCTV.
When ICAP was initially launched, the Fly-Eye HD Profiler System developed by Clean Flow Systems was used. The technology has since been purchased by RedZone and it is capable of collecting and processing data on internal pipeline conditions including debris level, flow levels, ovality, H2S erosion, and damage without requiring flow diversion, flow interruption or manhole ring removal. With the technology, it’s much easier to determine which segments require cleaning, significantly reducing costs. Just thirty percent of the pipe inspected by ICAP required cleaning.
