Jerome WWTF - Secondary Wastewater Treatment Plant in Jerome, Arizona

Jerome WWTF is a municipal wastewater treatment facility located in Jerome, Arizona, a historic mining town in the Black Hills of Yavapai County. The plant serves a small population of approximately 700 residents, reflecting the town's modest size and rural character. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 264.98 thousand gallons per day and a current discharge volume of 170.34 thousand gallons per day, the plant operates below its capacity, indicating room for future growth or seasonal variability. Treated effluent from Jerome WWTF ultimately drains into the Verde River watershed, a critical water source for central Arizona. The Verde River supports diverse aquatic life and provides water for agriculture and communities downstream, eventually flowing into the Salt River and contributing to the Phoenix metropolitan area's water supply.

Jerome WWTF discharges into the local drainage that feeds the Verde River, a major tributary of the Salt River. The Verde River watershed is ecologically significant, supporting riparian habitats and species such as the southwestern willow flycatcher. Downstream, the river flows into the Salt River and then to the Gila River, which is part of the Colorado River basin. Protecting water quality in this arid region is essential for maintaining aquatic ecosystems and regional water resources.
