AWWA ACE63099

This slide presentation outlines the impacts of valve location and reliability on distribution system operation. Project objectives were to:develop a rationale for valve location to enhancesystem reliability;develop a software tool for analysis of valveimportance for efficient pipe segment isolation;assist water utilities in minimizing customerimpacts from pipe failures during repair of pipes; and, develop a Strategic "Valving" Methodology toprovide guidance for efficient management ofvalves.Topics outlined include: system-wide rules; Functional Requirements in Case ofWater Main Break; Valve Reliability; Example Network Showing Valve Locations; Simple Hypothetical Pipe Network; Three Levels of Analysis; Tier 1 Performance Indicators; data requirements; Strategic Valve Management ModelSoftware Requirements; hypothetical water main network; Hypothetical Network Valve Prioritization; Direct Customers Affected by Average WaterMain Break for a Water Distribution SystemDirect Customers Affected by Average; stages of operation; improvement in valve operability; annual cost for valve O&M; Capital Costs of Valves(New Construction and Replacement); Alternate Strategies for Reducing Out-of-Service Customers; Chester Water Authority ¿¿¿¿¿¿¿¿ StatisticsNew Garden Section; System Characteristics for FourScenarios; Performance Indicators for CWA underFour Scenarios; Segments Having Largest Number ofPipes in the CWA Network; Segments Having Largest Number ofPipes in Unintended Isolations; Segments Having Maximum Number of Customersfrom Segments and Unintended Isolations; Most Critical Valves in CWA Systemin Terms of Affected Customers; Methodology for Application of SVMM; and, suggested rules for valve addition.
