The Ashley Valley Water Treatment Plant, Duchesne Valley Water Treatment Plant and the Don A. Christiansen Water Treatment Plant all have different challenges in treating the raw water as it comes into the plant. These challenges are heavily influenced by natural and anthropogenic influences in the surrounding watershed. Some of these challenges include seasonal shifts in turbidity levels causing the operators to switch to a water source that has higher total organic carbon. Algal blooms in the spring and fall significantly increase filter head loss. Changes in the landscape due to fire have augmented the potential for more organic material and sediment to enter the waterway. Another challenge is having a major highway so close to the river that when a vehicle crashes there is a probability that pollutant material may enter the waterway. To determine water quality challenges and solutions within each watershed and to measure water quality coming into these 3 plants I regularly sample 5 reservoirs and 22 river sample sites. Working together, plant managers and operators continue to produce water that is safe to drink despite the many challenges that they face while treating the water.
