UPTON LAGOON Wastewater Treatment Plant, Weston County, Wyoming

UPTON LAGOON is a wastewater treatment facility located in Weston County, Wyoming, United States. The plant serves a small population of around 1,100 residents, providing secondary treatment to municipal wastewater. As a lagoon-based system, it relies on natural biological processes to treat sewage before discharge. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater. With a designed capacity of 908.50 cubic meters per day and an average discharge volume of 469.39 cubic meters per day, the facility operates well within its capacity. The treatment process is typical for small communities in rural Wyoming, where lagoon systems are common due to their low operational costs and effectiveness. The treated effluent from UPTON LAGOON is discharged into local streams that eventually drain into the Missouri River basin. This watershed supports agricultural activities and provides habitat for diverse aquatic species. The plant's secondary treatment helps protect downstream water quality, particularly in the semi-arid environment of eastern Wyoming where water resources are limited.

UPTON LAGOON discharges into local waterways that flow into the Cheyenne River, a tributary of the Missouri River. The Missouri River basin is a major ecological corridor in the Great Plains, supporting fish species such as pallid sturgeon and migratory birds. The plant's secondary treatment reduces organic pollutants and nutrients, helping to maintain water quality in this agriculturally important region.
