Abstract
The purpose of this project was to use reverse flow sensing meters to better understand the frequency of reverse flow and identify the conditions in distribution systems that promote backflow, and develop guidance for utilities on reducing the occurrence of reverse flow promoting conditions. This guidance is based upon meter data collected from a variety of utilities, in-depth case studies of backflow promoting conditions, and development and application of a testing protocol for the accuracy of reverse flow sensing meters.
