Pueblo WWTP - Municipal Wastewater Treatment in Pueblo, Colorado

Pueblo WWTP is a municipal wastewater treatment facility located at 1211 South Queens Avenue in Pueblo, Colorado. Serving an estimated population of 107,577, the plant is a key component of the city's wastewater management system, operating under the regulatory framework of the U. S. Clean Water Act. As a large agglomeration serving over 100,000 people, the plant is expected to provide at least secondary treatment under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program. The Colorado Department of Public Health and Environment issues and enforces permits for such facilities, ensuring compliance with water quality standards. The plant's treated effluent is discharged into the Arkansas River, which flows through southeastern Colorado and eventually into the Mississippi River system. The Arkansas River supports diverse aquatic life and is an important water resource for agriculture and recreation in the region. Proper treatment at Pueblo WWTP helps protect downstream water quality and ecological health.

Pueblo WWTP discharges into the Arkansas River, a major tributary of the Mississippi River that drains the eastern slopes of the Rocky Mountains. The river supports a variety of fish species and provides habitat for migratory birds along the Central Flyway. Downstream, the Arkansas River flows through agricultural areas and semi-arid plains, where water quality is critical for irrigation and municipal use. The plant's operations help maintain the ecological balance of this important river system.
