New York Water Supply Infrastructure Study. Volume 3. The Bronx and Queens.

Abstract

This report describes an evaluation of the water distribution system in the Bronx and Queens, with special emphasis on water main breaks. The report presents a statistical analysis of breaks by sizes, causes, and season, among other considerations. It also examines trends in break rate with age of pipe and determines that the pipes are deteriorating with time, although these effects are masked somewhat by different laying practices and pipe materials. Criteria for determining which pipes should be replaced are developed. These criteria are based on a number of factors, most important of which are break cost, replacement costs, rate of pipe deterioration, and interest rate. The actual break rates of potential pipe replacement projects are compared with the critical break rate to determine which pipes should be replaced. Listings of replacement projects, and their costs, are then presented.
