HUDSON STP Wastewater Treatment Plant, Weld County, Colorado

HUDSON STP is a municipal wastewater treatment facility located in Weld County, Colorado, serving a population of approximately 1,598 residents. The plant is situated in an inland, agricultural region east of the Rocky Mountains, where water resources are critical for both community and environmental health. The plant provides secondary treatment, a standard level for small communities in the United States. With a designed capacity of 946.35 cubic meters per day and a current discharge volume of 757.08 cubic meters per day, it operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. These permits set limits on pollutants to protect water quality. The treated effluent from HUDSON STP ultimately drains into the South Platte River basin, which flows through Colorado and Nebraska before joining the Platte River. This watershed supports diverse aquatic life, agricultural irrigation, and municipal water supplies downstream. Proper treatment helps maintain the ecological health of these water bodies.

The plant discharges into local waterways that feed into the South Platte River, a major tributary of the Platte River system. This basin provides critical habitat for fish and wildlife, including species such as the plains killifish and the endangered whooping crane during migration. The region's semi-arid climate makes water quality management essential for sustaining both ecological and agricultural needs.
