MWH Soft announced Generation V5 of H2OSURGE for AutoCAD and InfoSurge for ArcGIS. The new version includes features that directly compute volumes of leakage and breaks in pipes, improving distribution system water quality maintenance and management and enhancing protection from potential contaminant intrusion during low (or negative) pressure transient events. Generation V5 also introduces advanced surge modeling functionality that gives engineers the ability to simulate leaks and line breaks and assess their resulting impacts on distribution system flows and pressures. These capabilities allow users to more accurately predict and eliminate potential weak spots in their distribution systems and prevent intrusion events with greater confidence.
