Department Project Title Project Number
Public Works Assess and Repair 16-inch Water Transmission Main UT1801
Project Description
This project will consist of assessing the 16-inch concrete bar-wrap pipe (BWP) water transmission main that begins at the Airport
Freeway entry point and extends to the Conn Ground Storage Tank. This transmission main transports water from the City of Fort
Worth to the City of North Richland Hills. The total length of pipe to be inspected is approximately 8,300 linear feet. There are 7
different phases to the assessment: site reconnaissance and project planning, transient pressure monitoring, leak and air pocket
detection, electromagnetic (EM) inspection, pipe performance curve, final report, and field verification/validation. These seven
phases will identify the pipes that need to be reconstructed or rehabilitated. Once the assessment has been completed, staff will
begin planning the identified necessary repairs and or section replacements. Staff has already identified a section of pipe, roughly
300 feet, along Airport Frwy that will be repaired as part of this project. An entry point and exit point will be constructed to gain
access for the assessment
Project Justification
This water transmission main is critical to the supply of water for the city. The city has four main entry points throughout the water
system. This entry point supplies water for citizens in the south to the middle of the city. The majority of the pipeline is not in the
City of North Richland Hills. Staff has made repairs to two areas of the pipe that have been damaged by franchise utilities that have
bored next to the pipe from years past. As the the pipe is concrete bar wrapped pipe, when the concrete that surrounds the pipe is
damaged, the bars that wrap the pipe become susceptible to moisture, causing corrosion. Staff cannot televise a water main to gain
the overall condition of the pipe. The EM inspection will identify the sections of pipe that will need to be replaced or rehabilitated,
saving millions of dollars that would otherwise be needed to reconstruct the entire pipeline.
