Assessing and Maintaining the 24-inch and Larger Interceptor in our Sanitary Sewer Systems

Assessing and maintaining the 24-inch and larger interceptors in our sanitary sewer systems have presented expensive challenges and critical risks. For the Fort Worth ICAP project, the team uses multi-sensor inspection platforms developed and built by RedZone Robotics. The floats contain a high-definition TV camera, sonar module and a 3-D Laser module to gather data regarding condition of the pipe. Combined, these systems have inspected more than 5 million linear feet of wastewater infrastructure worldwide. With the high-resolution images and models, inspectors can examine the condition of pipe walls, location and amount of debris, and defects in the pipe wall.

One of the most useful pieces of data collected by ICAP is the measurement of the inside diameter of the pipe. These measurements of the interior pipe wall are compared to the original specifications to determine the wall thickness loss. This loss is then used to assign pipe segment condition scores, known as Remaining Useful Life (RUL). There are five RUL scores describing loss of wall thickness. A score of one has the lowest amount of material loss, and an estimated lifespan of more than 35 years. Pipe segments scoring a five have significant material loss and are considered to be in imminent failure and in need of emergency rehabilitation. Flexible pipes are scored based on the measured ovality. With the RUL estimates, the City has targeted rehabilitation efforts to portions of pipelines that are at risk of failure, rather than traditional manhole-to-manhole replacement.

The Fort Worth Water Department presently is conducting the world’s largest known implementation of ICAP to inspect the city’s large diameter sewer lines. Through seven years, Fort Worth has inspected more than 198 miles of large-diameter interceptor, saved more than $8 million in cleaning costs and $26 million in reduced capital improvements. These savings result from the Water Department’s ability to focus financial resources on only the interceptor sections that need attention. Fort Worth found that only 30% percent of inspected pipes needed cleaning. Previously, traditional approaches would have required that 100% of the interceptors be cleaned before inspection could begin. On average, less than 10% of the inspected footage each year is identified as needing short-term or emergency rehabilitation
