Colorado, USA, 21 June 2006: In its ongoing quest to equip the global drinking water industry with the GIS-centric modeling and management solutions, MWH Soft announced on June 21, the worldwide release of InfoWater Valve Criticality Modeling (VCM). The new InfoWater Suite extension gives users expanded power and 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.
Valve criticality assessment identifies which valves most crucially affect the scale of impact of potential system failures. InfoWater VCM automatically carries out a comprehensive assessment of the hydraulic impact of valve operations on customer service levels, either when the valves are shut or fail to shut, during planned or emergency work. 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. Pinpointing these 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).
