NUCLA WWTP - Secondary Treatment Plant in Montrose County, Colorado

NUCLA WWTP is a municipal wastewater treatment facility located in Montrose County, Colorado, serving a population of 1,130. The plant provides secondary treatment, a standard level for small communities in the United States, ensuring compliance with Clean Water Act requirements. The plant has a designed capacity of 757.08 m³/day and discharges a similar volume of treated effluent. As a small facility, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated wastewater is discharged into a local water body that drains into the Colorado River basin. This region is part of the arid Western United States, where water resources are critical for agriculture, ecosystems, and communities. The plant plays a key role in protecting downstream water quality in this sensitive watershed.

The plant discharges into a tributary of the Colorado River basin, which ultimately flows to the Gulf of California. This arid region relies on careful water management to support aquatic life and agricultural use. The Colorado River system is ecologically significant, providing habitat for native fish species and supporting migratory birds.
