Pinellas County Transmission Force Main Inspection and Replacement Program
What could you be doing to stay one step ahead of your existing infrastructure as it approaches the end of its useful life? Joe Graham, JD, MBA, PE with Pinellas County (County) and Weston Haggen, PE with Reiss Engineering are co-presenting on the County’s proactive approach in evaluating their force main system following the failure of a large force main. The suspected cause of failure was corrosion from build-up of hydrogen sulfide resulting in the formation of sulfuric acid leading to corrosion and eventual breakdown of the pipe’s structural characteristics. The County has already conducted a significant amount of evaluations on their large diameter force mains and associated air release valves located in the northern and southern portions of Pinellas County. Based on these evaluations the County has complete a significant amount of ARV replacements and key force main replacements. This presentation will include background on the 30-inch force main failure, inspection and replacements to date, the future of the program, and lessons learned.
