Automated Hydrant Testing and Fire Flow Analysis

By Wallingford Software, UK

Water distribution authorities around the world have formal obligations to supply water to fight fires, and to check regularly that they meet these obligations. Underprovision of this vital community resource is not acceptable. However, overprovision also could have its problems. Because fire flow is often the dominant factor in sizing a network, particularly in smaller systems, overprovision for fire flow means oversizing the network, leading to costly capital investment. The difficulties of finding the right balance between these two conflicting factors underlines the importance of accurate fire flow analysis.

This paper describes how modeling can now help with such analysis, automating the process and making major savings on what is at present a time-consuming and costly task.
