In this episode, our old Dragnet heroes Joe Friday and Bill Gannon follow the flow of the water at a treatment plant to inspect for cross-connections. Checkpoints along the way: submerged inlets in chemical feed tanks; connections between potable water lines and process water; split chemical feeds in the chlorination system; surface washes; filter to waste connections; connections to pumps, hose bibs; vacuum breakers; backflow prevention assemblies; and the plant cross-connection control program.
Created for the U.S. EPA Office of Water by the National Environmental, Safety and Health Training Association, the "Before You Begin..." series of videos are intended for training and refreshing the knowledge of state drinking water sanitary survey inspectors, just prior to an inspection. The videos in the series often also are used in public community sessions and councils to inform the public about the responsibilities and difficulties faced by local officials in maintaining their public water facilities, particularly small systems.
