Paper ID: C2025-00303 ABSTRACT: Watermain break analyses often prioritize failures attributed to corrosive soils or water hammer, but cases of watermain corrosion in non-corrosive open atmosphere conditions are often overlooked. This paper presents a noteworthy case study on the condition assessment of a 80 year old watermain section in a pump station that experienced corrosion despite being exposed to a non-corrosive environment. The study employs a comprehensive approach to condition assessment, incorporating visual examination, potential surveys, magnetic flux measurements, and field metallographic replication. By examining the physical and metallurgical characteristics, the study seeks to identify the underlying factors contributing to the corrosion phenomenon. The findings highlight the importance of considering diverse environmental and operational factors in watermain break analyses, providing insights into the impact of non-corrosive atmospheric conditions and informing improved infrastructure design, maintenance practices, and corrosion prevention strategies.
