Centro Sur Bachíniva Wastewater Treatment Plant, Bachíniva, Chihuahua, Mexico

Centro Sur Bachíniva is a municipal wastewater treatment facility located in Bachíniva, Chihuahua, Mexico. The plant serves a small population of 1,110 residents, reflecting its role in a rural or small-town setting. Its location in the Sierra Madre Occidental region influences the local water management needs. The plant provides secondary treatment, which is typical for small communities in Mexico under the national water quality regulations (NOM-001-SEMARNAT). Secondary treatment effectively removes organic matter and suspended solids, meeting basic discharge standards. The facility has a designed capacity of 864 m³/day and currently treats 432 m³/day, indicating it operates at 50% capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Pacific Ocean via the Río Fuerte or Río Yaqui basins. The surrounding watershed supports agricultural activities and diverse ecosystems. Proper treatment helps protect downstream water quality and aquatic life in this semi-arid region.

The plant discharges into the Río Santa María or a tributary of the Río Conchos, which flows into the Río Bravo (Rio Grande) and eventually the Gulf of Mexico. The watershed supports agricultural irrigation and provides habitat for native fish species. The region's semi-arid climate makes water quality management critical for both human use and ecological health.
