Overview
Coolidge Airport WWTF is a projected wastewater treatment facility in Pinal County, Arizona, designed to serve approximately 30,000 people. It will operate under the US Clean Water Act framework.
Coolidge Airport WWTF is a planned wastewater treatment facility located at Coolidge Municipal Airport in Pinal County, Arizona, United States. The plant is projected to serve a population of around 30,000, positioning it as a medium-sized municipal facility within the region. As a projected facility, specific treatment processes and capacity details are not yet finalized. However, US plants of this scale typically operate under the National Pollutant Discharge Elimination System (NPDES) permits issued by the Arizona Department of Environmental Quality, requiring secondary treatment as a minimum standard under the Clean Water Act. The plant's discharge will likely flow into local washes and arroyos that drain into the Gila River basin, ultimately reaching the Colorado River and the Gulf of California. This arid region requires careful water management to protect downstream ecosystems and water quality.
Environmental context
The facility is located in the Gila River basin, an arid watershed in central Arizona. Treated effluent would likely discharge into ephemeral washes that feed the Gila River, a tributary of the Colorado River. The Colorado River system supports critical habitats for native fish species and provides water for agriculture and urban areas across the southwestern United States. Protecting water quality in this basin is essential for maintaining ecosystem health in a water-scarce region.
