- Abstract
- This report provides an overview of post-earthquake systems reliability, and makes recommendations to enhance post-earthquake operability of domestic water systems and/or alternate waters supply systems and/or enable quick restoration of service following an earthquake. This report and associated projects are the results of recommendations from the Post-Earthquake Fire and Lifeline Workshop held in Long Beach, California, January 30 - 31, 1995. The report includes information and procedures, developed from previous research and observations, to assess earthquake reliability of municipal water supplies focusing on water for fire suppression. The relevant information base includes experience from previous earthquakes, overall system operation, and performance of individual system components. Component and system failure mechanisms are also addressed, and mitigation approaches are identified and developed. The report also considers alternatives to enhance restoration of service following earthquakes. Alternatives include hardware improvements, system operation optimization, development of alternative waters supplies, and use of geographic information systems, GIS.
