Clarkdale WWTF - Secondary Wastewater Treatment in Clarkdale, Arizona

Clarkdale WWTF is a municipal wastewater treatment facility located in Clarkdale, Arizona, serving a population of approximately 2,486 residents. The plant operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater to protect water quality. As a facility in an arid region, it plays a key role in managing water resources in Yavapai County. The plant provides secondary treatment, a standard level for communities of this size in the United States. Its designed capacity is 946.35 megaliters per year, with an actual discharge volume of 567.81 megaliters, indicating operational capacity below design levels. The plant is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Arizona Department of Environmental Quality, ensuring compliance with effluent limits. The treated effluent is discharged into the local watershed, which ultimately drains into the Verde River, a tributary of the Salt River and part of the Colorado River basin. This water supports downstream ecosystems, including riparian habitats and agricultural uses, in a region characterized by semi-arid climate and water scarcity. The plant's operations contribute to maintaining water quality in the Verde River system.

Clarkdale WWTF discharges into the Verde River watershed, which flows into the Salt River and eventually the Colorado River. The Verde River supports diverse aquatic life and riparian vegetation in a semi-arid landscape, making water quality management critical for ecological health. Downstream, the river provides habitat for native fish species and migratory birds, and its flows are essential for agricultural and municipal water supplies in central Arizona.
