New York Water Supply Infrastructure Study. Volume 4. Staten Island.

Abstract

This report describes an evaluation of water main breaks in the Staten Island, New York, water distribution system. The report describes a statistical evaluation of historical pipe breaks and identifies patterns and trends in the data, including such things as the increase in circumferential pipe breaks during winter months and an increase in longitudinal breaks (probably due to surges) during summer months. The actual break rates (in breaks per year per mile) were calculated for water mains with a history of breaks. This rate was compared with a critical break rate to determine which water mains should be replaced. The critical break rate was based on an economic evaluation of costs of replacement versus pipe repair and lost water from the existing mains. A list of recommended replacement projects and their costs is presented.
