Green River Lagoon Wastewater Treatment Plant, Green River, Wyoming

Green River Lagoon is a municipal wastewater treatment facility located in Green River, Wyoming, serving a population of about 12,515. The plant is situated in Sweetwater County and is part of the city's infrastructure for managing domestic wastewater. As a lagoon system, it provides natural treatment through settling and biological processes, typical for smaller communities in the region. The plant operates under the regulatory framework of the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all wastewater discharges. The plant's design capacity and discharge volume are not publicly reported, but the population served suggests a moderate-scale operation. Treated effluent from Green River Lagoon is discharged into the Green River, which flows southward to join the Colorado River. This river system is ecologically significant, supporting diverse aquatic life and providing water for agriculture and communities downstream. The plant's discharge is regulated to protect water quality in this important watershed.

Green River Lagoon discharges into the Green River, a major tributary of the Colorado River. The Green River flows through Wyoming, Utah, and Colorado before joining the Colorado River in Canyonlands National Park. This watershed supports a variety of fish species, including the endangered Colorado pikeminnow, and provides critical habitat for migratory birds. The plant's operations are subject to water quality standards aimed at preserving the ecological health of this arid-region river system.
