Prescott Airport WWTF - Wastewater Treatment in Prescott, Arizona

Prescott Airport WWTF is a municipal wastewater treatment facility located in Prescott, Arizona, serving an estimated population of 54,000. The plant is situated in Yavapai County, within the semi-arid climate of the southwestern United States. As a facility serving a medium-sized agglomeration, the plant is subject to the U.S. Clean Water Act and operates under an EPA NPDES permit issued by the Arizona Department of Environmental Quality. For plants of this scale, secondary treatment is typically required, with possible additional nutrient removal depending on the receiving water body's sensitivity. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Verde River, a tributary of the Salt River, and then into the Gila River and Colorado River system. This water is critical for downstream ecosystems and agricultural uses in the arid region.

The plant discharges into the Upper Verde River watershed, which supports diverse aquatic life and riparian habitats in an otherwise arid region. The Verde River flows into the Salt River, a key water source for the Phoenix metropolitan area, and eventually reaches the Colorado River. Protecting water quality in this basin is essential for maintaining ecological balance and regional water supplies.
