The Fort Collins Water Treatment Facility (Colorado) is a 70‐mgd (270‐ML/d) plant that uses two raw water sources: Horsetooth Reservoir, and the Cache la Poudre River. Due to water rights, the treatment plant desires to treat 100 percent Poudre River water during the period of spring snowmelt, when the river is at peak flow. Due to the challenging water quality of the river during runoff, the plant has been forced to blend river water with that of the reservoir to meet its in‐house finished water quality standards. To avoid blending and to treat 100 percent of the source water, it was necessary to conduct extensive bench‐ and pilot‐scale experiments to develop the desired process chemistry. The results presented here are the culmination of three runoff seasons' worth of experiments.
