A little spark - miles away - changed the universe for the Duchesne Valley Water Treatment Plant. It resulted in a massive forest fire, source water quality degradation, treatment challenges, a cancelled project at 95% design, and new project to address post fire realities.

This presentation outlines how rapid things can change when a forest fire hits the watershed, what was done operationally to address the post-fire water quality, and a new process improvement project to provide long-term plant resiliency against the effects of the fire. The presentation includes how treatment processes were impacted by the post-fire water quality and the selection process for determining whether pretreatment was needed upstream or downstream of the existing ozone system.
