    Pressure transient propagation is a wholly natural consequence of any change in operating conditions for a fluid carrying system. Rapid changes in flow conditions generate surge conditions that may result in system failure. The analysis of these phenomena has progressed over the past 100 years from empirical research aimed at the protection of large-scale pipeline and plant networks to the development of computing simulations to support system design. Pressure surge analysis is therefore a consideration in the design and operation of all fluid systems: the objective of such an analysis being the prediction, control and suppression of transients. This paper presents the background to the development of surge alleviation, from traditional pipeline protection to applications within building drainage and vent systems, thereby stressing that the system failure consequences of transient propagation are dependent on the particular system, independent of absolute surge pressure, and that system protection criteria may be developed that apply regardless of the system or the severity of the transient. © The Chartered Institution of Building Services Engineers 2005.
