MWH Soft, a global provider of environmental and water resources applications software, announced the worldwide availability of Generation V5 of H2OSURGE for AutoCAD (Autodesk, San Rafael, CA) and InfoSurge for ArcGIS (ESRI, Redlands, CA). The latest release of these groundbreaking hydraulic transient management tools marks a new high point in the evolution of the industry's premier and widely acclaimed pressure surge analysis applications, H2OSURGE and InfoSurge.

The new version is packed with critical 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. Low pressure in drinking water distribution systems is a well-known risk factor for outbreaks of waterborne disease. Low pressure transient events can cause the intrusion of contaminated water into pipes with leaky joints, cracks or breaks. This is especially important in systems with pipes below the water table. Generation V5 marks the latest in a series of important releases that have focused on solving significant industry challenges associated with these pressure-related intrusion events.

Anticipating and controlling transient response is also critical in ensuring the protection, integrity, and effective operation of drinking water distribution systems. Transient responses can introduce pressures of sufficient magnitude (upsurge) to burst pipes and damage equipment. The resulting repercussions can include loss of property and life. Transient responses can also produce sub-atmospheric pressures (downsurge) that force dirty water and pathogens into the system, leading to grave health consequences. Generation V5 introduces advanced surge modeling functionality that gives engineers the unprecedented 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 than ever before. The new version also delivers blazing performance gains, making transient analysis an even easier and more enjoyable task.

The state-of-the-art H2OSURGE and InfoSurge transient flow analysis solution addresses every facet of transient analysis and utility infrastructure management and protection, delivering the highest rate of return in the industry. It provides the framework needed to quickly assess the effects of pump station power failures, pump startup, valve closures, and rapid demand and pump speed changes as well as the efficacy of any combination of surge protection devices. With this information, water utilities can now more accurately predict the development of unacceptable operating conditions in their distribution systems, identify risks, formulate and evaluate sound protective measures, and determine improved operational plans and security upgrades.

Upgrades to H2OSURGE and InfoSurge are now available worldwide by subscription to the Gold program. Subscription members can immediately download the new version free of charge directly from The MWH Soft Subscription Program is a friendly customer support and software maintenance program that ensures the longevity and usefulness of MWH Soft products.
