Miami-Dade Case Study: Managing and Minimizing Pipeline Outages through the Use of Carbon Fiber

In order to minimize disruptions to residents and the associated financial and political costs, Miami-Dade Water and Sewer Department MDWASD has adopted a proactive approach to managing their large diameter pipeline system. Through the widespread use of precision pipeline inspection techniques, the MDWASD pipeline systems are now able to be repaired or replaced before pipeline integrity issues cause unscheduled shutdowns. One pipeline replacement method is the application of Carbon Fiber Reinforced Polymer (CFRP) composites to the interior of the pipeline structure to create a new pipe within the pipe. The use of a CFRP liner, a 100% stand-alone structural solution, as a precision replacement method is very effective in combination with a comprehensive inspection program. This paper and presentation will offer readers and attendees specific information on how Miami-Dade has used their CFRP program, coupled with precision inspection, to manage and minimize outages, creating an overall increase in pipeline reliability. Discussion will center upon an overview of the important correlation between inspection technologies and CFRP upgrades, best practices in designing and installing CFRP systems and discussion of Miami-Dade's process for successful implementation of CFRP projects.
