Winter Park WSD Wastewater Treatment Plant, Winter Park, Colorado

Winter Park WSD is a municipal wastewater treatment facility located in Winter Park, Grand County, Colorado. The plant serves a population of approximately 1,600 residents in this mountain community, situated in the Rocky Mountains near the Fraser River. As an advanced treatment facility, it provides a high level of pollutant removal to protect the sensitive alpine watershed. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all wastewater discharges. For advanced treatment plants serving small communities like Winter Park, typical processes include biological treatment followed by filtration or nutrient removal to meet stringent water quality standards. The plant has a designed capacity of 946.35 cubic meters per day and currently discharges 492.10 cubic meters per day, indicating operational headroom. The treated effluent is discharged into the Fraser River, which flows northward to join the Colorado River near Granby. This watershed is ecologically significant as part of the Upper Colorado River Basin, supporting native trout species and providing water for downstream communities and agriculture. The plant's advanced treatment helps maintain water quality in this headwater stream, which is critical for the broader Colorado River ecosystem.

The plant discharges into the Fraser River, a tributary of the Colorado River. The Fraser River flows through Grand County before joining the Colorado River near Granby, Colorado. This headwater region supports cold-water fisheries, including native cutthroat trout, and provides habitat for aquatic insects and riparian wildlife. The Colorado River downstream is a vital water source for irrigation, municipal supply, and hydroelectric power across the southwestern United States.
