Water utility managers generally agree that water meters, especially mechanical water meters, experience a degradation of accuracy over time. This degradation is a function of several factors, such as wear, water quality, water velocities, throughput volumes, and installation and handling. Both a thorough understanding of the factors that affect meter accuracy and the ability to pinpoint, if possible, the optimal lifespan of any particular type of water meter in a residential distribution system are desirable for improved system management. The purpose of this article was to investigate the relationship between meter accuracy degradation and factors such as age, wear, and throughput for in-service water meters pulled from utilities across the United States. The information contained in this article is intended to provide insight to water utility managers and decision-makers about meter replacement programs and schedules.
