- Abstract
- A survey of the characteristics of underground water pipeline systems which may affect their seismic performance was conducted in order to: (1) establish a data base on the types of water pipelines that are in current use, including materials, sizes, types of joints, depths of burial, and backfill conditions; (2) to determine perceptions of seismic risk among water utilities; and (3) to collect data on seismic performance of water pipelines. The survey was conducted by questionnaire which was mailed to 516 water utilities, including wholesalers and retailers, in the United States. This report includes discussions on descriptions of existing systems, perceptions of seismic risk, and experiences of damage in pipelines.
