Lifeline Infrastructure Systems for Your Water Supply, Transmission, and Distribution Systems: A Step-Wise Approach to the Design and Construction of Seismic-Resistant Pipe, Fittings, Valves, and Fire Hydrants
Publication: Lifelines 2022
ABSTRACT
This paper focuses on a complete water supply, transmission, and distribution system for pipe, fittings, valves, and fire hydrants which employ joint systems that deflect, expand, contract, and provide end-wise thrust capacity. Such a comprehensive system from a single manufacturer is of value and interest for all utility system owners and providers, especially those in areas of seismic and storm risk. The system has been tested by Cornell University’s Geotechnical Large Scale Lifelines Testing Facility and certified in compliance with ISO 16134. The audience will learn of recent product developments demonstrating performance through 30-in. diameter and including fittings, valves, and fire hydrants. This investigation will be informative for municipal water system owners and operators and their design consultants for the purpose of writing performance-based material specifications which strengthen water system resiliency. Utilizing pipe products available to everyone plus modern and innovative joint technology, this is a robust and user-friendly system from an installation, operation, and maintenance standpoint. Specifically, the system utilizes AWWA Standards, joints, and construction practices familiar with utilities and installing contractors and meets or exceeds ISO 16134 seismic requirements. A step-wise approach to system-wide design and construction will be presented which addresses areas of highest risk and moves outward to areas of lower risk.
