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 enhance
system reliability;
develop a software tool for analysis of valve
importance for efficient pipe segment isolation;
assist water utilities in minimizing customer
impacts from pipe failures during repair of pipes; and,
develop a Strategic "Valving" Methodology to
provide guidance for efficient management of
valves.
Topics outlined include: system-wide rules; Functional Requirements in Case of
Water 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 Model
Software Requirements; hypothetical water main network; Hypothetical Network Valve Prioritization; Direct Customers Affected by Average Water
Main Break for a Water Distribution System
Direct 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 ¿¿¿¿¿¿¿¿ Statistics
New Garden Section; System Characteristics for Four
Scenarios; Performance Indicators for CWA under
Four Scenarios; Segments Having Largest Number of
Pipes in the CWA Network; Segments Having Largest Number of
Pipes in Unintended Isolations; Segments Having Maximum Number of Customers
from Segments and Unintended Isolations; Most Critical Valves in CWA System
in Terms of Affected Customers; Methodology for Application of SVMM; and, suggested rules for valve addition. Includes tables, figures.
