Workers learn the benefits of and techniques for unidirectional flushing of water distribution systems.
Unidirectional flushing uses targeted, high-velocity water flow moving from source to hydrant in an outbound direction to scour the distribution system. Unidirectional Flushing DVD explains concepts and techniques of unidirectional flushing; how to develop a flushing plan using paper maps; how computer aided mapping simplifies the project; benefits verses traditional flushing techniques; and the benefits to consumers and the community.
Viewers also watch a case study that explains Virginia Beach, Virginia's unidirectional flushing program. (20:25 minutes)
