MWH Soft expands H2ONET with Valve Criticality Modeling

Broomfield, USA, 27 December 2006 – In its ongoing quest to equip the global drinking water industry with comprehensive and innovative modeling solutions, MWH Soft has announced the release of H2ONET Valve Criticality Modeling (VCM). This new H2ONET Suite extension gives users flexibility in identifying all vulnerabilities affecting their water distribution system reliability, estimating the extent and potential consequences of infrastructure failure on customer service levels, optimizing the allocation of rehabilitation and maintenance resources, and improving knowledge of system operation.

The valve criticality assessment process identifies which valves most crucially affect the scale of impact of potential system failures. H2ONET VCM automatically carries out a comprehensive assessment of the hydraulic impact of valve operations on customer service levels when valves are shut or fail to shut during planned or emergency work.

Pinpointing such critical valves requires an understanding of the risk (probability and consequence) should the valve fail to shut. Consequence is measured in terms of the numbers of properties (and customers) that would be disconnected or experience unacceptable levels of service (e.g., low pressure or loss of supply). This information is critical in focusing future expenditures (maintenance and replacement) on the valves most critical to maintaining the serviceability of these key infrastructure assets.

The H2ONET software suite is a CAD-based water distribution engineering solution. Its network modeling technology addresses utility infrastructure management, optimization and protection.

Built atop AutoCAD, H2ONET delivers integrated real-time network modeling, GIS data exchange, spatial database query and analysis across multiple data types, as well as the sophisticated mapping required for complete infrastructure (asset) management and business planning. Its computational algorithms allow engineering professionals to directly access CAD and GIS datasets; extract pertinent modeling information; and automatically construct, skeletonize, load, calibrate, analyze, design, operate and optimize any network model.

The resulting modeling sets new levels of scalability, reliability, functionality and flexibility within the powerful AutoCAD environment. Using these advanced tools, utilities can easily simulate and evaluate various conditions, pinpoint system deficiencies, and determine the most cost-effective physical and operational improvements to maximize efficiency, achieve optimum performance and regulatory compliance, meet new security challenges, and enable more reliable operations.
