New Sight for Old Pipes
When large sewer interceptors fail, the damage can be extensive and the emergency repairs costly. But pre-emptively cleaning or replacing the pipes are expensive undertakings as well, especially when their condition isn’t known beforehand. To solve this dilemma for the Fort Worth Water Department, Freese and Nichols developed the multi-year Interceptor Condition Assessment Program (ICAP). Sonar, 3-D lasers and high-definition video inspect pipes from the inside, determining where repairs are needed and, just as importantly, where they aren’t. The largest known implementation of this technology in the world, ICAP has already saved the City $4.5 million in cleaning costs and $3 million to $6 million in prevention of line failures.
