Columbus Village of Wastewater Treatment Plant - Columbus, New Mexico

The Columbus Village of wastewater treatment plant is located in Columbus, Luna County, New Mexico, serving a small community of 1,664 people. The facility operates as a municipal wastewater treatment plant under the regulatory framework of the United States Clean Water Act. The plant provides secondary treatment, which is the standard level for domestic wastewater in the U.S. It has a designed capacity of 227.12 thousand cubic meters and discharges approximately 227.13 thousand cubic meters annually, indicating near-capacity operation. As a small treatment facility, it is subject to EPA National Pollutant Discharge Elimination System (NPDES) permitting requirements. The plant's treated effluent is discharged into local water bodies that eventually drain into the Rio Grande basin. The Rio Grande is a major river system in the southwestern United States, supporting diverse aquatic life and providing water for agriculture and communities. The plant's operations are important for protecting local water quality in this arid region.

The Columbus plant discharges into the Rio Grande basin, which flows through New Mexico and Texas before reaching the Gulf of Mexico. This arid region relies heavily on the Rio Grande for irrigation and municipal water supply. The plant's secondary treatment helps protect downstream ecosystems, including riparian habitats and species adapted to the desert environment.
