Iliff Town of Wastewater Treatment Plant, Iliff, Colorado

The Iliff Town of wastewater treatment plant is a municipal facility located in Iliff, a small town in Logan County, Colorado. Serving a population of 220, the plant provides secondary treatment to meet state and federal water quality standards. As a small-scale facility, it plays a vital role in protecting public health and the environment in this rural agricultural region. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater. With a designed capacity of 113.56 megaliters per year, the facility manages the community's wastewater effectively. The treated effluent is discharged into local waterways that drain into the South Platte River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. This connection underscores the plant's role in maintaining water quality in a region where agriculture and livestock operations are prevalent, and where water resources are carefully managed.

The plant discharges into streams within the South Platte River watershed, which flows through northeastern Colorado and Nebraska before joining the Platte River and eventually the Mississippi River. This basin supports irrigated agriculture, wetlands, and wildlife habitat. Downstream ecosystems rely on consistent water quality, and the plant's secondary treatment helps reduce nutrient and pathogen loads that could otherwise impact aquatic life and downstream water users.
