Hayden Wastewater Treatment Plant, Colorado | Secondary Treatment for Small Community

The Hayden wastewater treatment plant is located in Hayden, Routt County, Colorado, serving a small community of approximately 1,700 residents. The plant provides secondary treatment, a standard level for municipal wastewater in the United States, and has a designed capacity of 946.35 cubic meters per day. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Colorado Department of Public Health and Environment. Secondary treatment is typical for small agglomerations in the US, ensuring removal of organic matter and suspended solids before discharge. The treated effluent is discharged into the local watershed, which ultimately drains into the Yampa River, a tributary of the Green River and part of the Colorado River Basin. This river system supports diverse aquatic life and provides water for agriculture and recreation in the region.

The plant discharges into the Yampa River watershed, which flows into the Green River and then the Colorado River. The Colorado River Basin is a critical water source for the southwestern United States, supporting ecosystems, agriculture, and urban centers. The Yampa River is known for its relatively natural flow regime and supports native fish species such as the Colorado pikeminnow and razorback sucker.
