MWH Soft Unveils Highly Anticipated InfoWorks TS for Comprehensive Hydraulic Transient Analysis
of Water Distribution Systems

Fourth Quarter 2010 Release to Deliver Unprecedented Transient Modeling Capabilities for Better Decision-Making

Broomfield, Colorado USA, June 16, 2010 — MWH Soft, a leading global innovator of wet infrastructure modeling and simulation software and technologies, today announced the fourth quarter release of InfoWorks TSfor advanced hydraulic transient analysis. The groundbreaking release will give InfoWorks WS users worldwide direct access to the industry’s fastest, most comprehensive and widely acclaimed pressure surge analysis application, with unsurpassed power to help them better preserve distribution system integrity and avert potential problems. The news reflects MWH Soft’s vanguard position in the water industry and its continuing commitment to delivering pioneering technology for enhancing the safety and reliability of the world’s water supply.

Anticipating and controlling transient response is critical to ensuring the protection, integrity, and effective/efficient operation of water distribution systems. Transient responses can introduce pressures of sufficient magnitude (upsurge) to burst pipes and damage equipment. The resulting repercussions can include extended service outages and loss of property and life. Transient responses can also produce sub-atmospheric pressures (downsurge) that can force contaminated groundwater into the distribution system at a leaky joint, crack or break, leading to grave health consequences. Sustained sub-atmospheric pressures may also lead to cavitation and water column separation, resulting in severe “water hammer” effects as the vapor cavity collapses.

The state-of-the-art, full-featured InfoWorks TS transient flow analysis solution will address every facet of pressure surge analysis and its role in utility infrastructure management and protection, delivering the highest rate of return in the industry. It will provide the engineer-friendly framework needed to quickly assess the effects of pump station power failures, pump startup, valve closures, rapid demand and pump speed changes, and the efficacy of any combination of surge protection devices. The program will also accurately simulate transient cavitation and water column separation, evaluate their intensity, and estimate their potential effects on the system.

Armed with this information, water utilities can more accurately predict the development of unacceptable operating conditions in their distribution systems, identify vulnerable areas and risks, evaluate and design sound protective measures, and determine improved operational plans and security upgrades. InfoWorks TS will also deliver blazing simulation speed, making transient analysis an even easier and more enjoyable task.

“Water utilities and engineering consulting firms around the world rely on MWH Soft’s superior end-to-end modeling and design solutions to manage and operate better, safer systems,” said Paul F. Boulos, Ph.D, Hon.D.WRE, F.ASCE, President and Chief Operating Officer of MWH Soft. “By augmenting our popularInfoWork WS with powerful hydraulic transient modeling capabilities, we are creating a comprehensive tool kit for the waterworks engineer. This milestone solution will be the only analysis, design and management software users need to work faster and smarter in a competitive environment — not only to power system performance, but to safeguard critical infrastructures and maximize their effectiveness in protecting public health.”
