Pinal County Eleven Mile Corner Rd WWTP | Advanced Treatment in Arizona

Pinal County Eleven Mile Corner Rd WWTP is a wastewater treatment facility located in Pinal County, Arizona, United States. The plant serves a small population of 220 residents and operates with advanced treatment capabilities, ensuring high-quality effluent. Its designed capacity of 75.71 units indicates room for future growth. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other contaminants. Under the US Clean Water Act, such facilities are regulated through National Pollutant Discharge Elimination System (NPDES) permits, which set strict effluent limits to protect water quality. The advanced treatment level suggests the plant may discharge to a sensitive water body or reuse the water for beneficial purposes. The treated effluent is discharged into the local watershed, which ultimately drains into the Gila River basin and then to the Colorado River. The arid Arizona climate makes water reuse and conservation critical. The plant's advanced treatment supports local water sustainability efforts, protecting downstream ecosystems and supporting groundwater recharge.

The plant discharges into the Gila River basin, a tributary of the Colorado River, which flows to the Gulf of California. The region's arid climate means that treated wastewater is a vital water resource for downstream communities and ecosystems. The advanced treatment helps protect sensitive aquatic habitats and supports water reuse for irrigation or environmental flows.
