A system and method is disclosed for facilitating the management of pipeline reliability, maintenance, repair, and/or replacement. Embodiments may be computer-implemented, and may be suitable for prestressed concrete cylinder pipe (e.g., PCCP). Method steps include inspecting the pipe and storing or inputting design and inspection parameters, as well as the maximum expected pressure within the pipe. A relation of pressure versus degradation (e.g., number of broken wires) may be used, which may have zones of risk or classifications corresponding to pipe management actions. The pipe may be analyzed for lack of prestress over various portions of circumference and length. The pipe rupture pressure, crack onset pressure, or can rupture pressure may be analyzed and compared to the expected pressure. The method may be tested and the inspection repeated while tracking changes. The action may involve, for instance, doing nothing, monitoring the pipe, repairing the pipe, or replacing the pipe.
