Multiple Choice

A continuous positive pressure in a distribution system is essential for preventing what event?

Keeping a water distribution system under continuous positive pressure ensures water always moves outward toward consumers rather than backward into the system. When pressure drops or downstream pressure becomes higher than upstream, reverse flow can occur—this is backflow. Siphonage and backpressure are mechanisms that can cause backflow, not the event itself. A backflow event is the reverse flow that can pull contaminants into the system through cross-connections. So, maintaining positive pressure is essential to prevent backflow events and protect water quality.
