Ciudad Acuña Wastewater Treatment Plant, Ciudad Acuña, Coahuila, Mexico

Ciudad Acuña wastewater treatment plant is a municipal facility located in Ciudad Acuña, Coahuila, Mexico. Serving an estimated population of 199,248, it is a significant infrastructure asset for the city, which lies on the border with the United States near the Rio Grande. The plant's designed capacity is 1.00 unit, indicating its scale relative to the population served. As a Mexican wastewater treatment plant, it operates under the national regulatory framework established by the Ley de Aguas Nacionales and Normas Oficiales Mexicanas (NOMs), which set discharge standards for municipal wastewater. The plant discharges treated wastewater into local waterways that ultimately flow into the Rio Grande (Río Bravo), a major river forming the US-Mexico border. The Rio Grande drains into the Gulf of Mexico, supporting diverse aquatic ecosystems and providing water for agriculture and communities in both countries. The plant plays a key role in protecting water quality in this transboundary basin.

The plant discharges into the Rio Grande basin, which flows southeast to the Gulf of Mexico. This river system supports critical habitats for fish, birds, and other wildlife, including migratory species. The region's semi-arid climate makes water quality management particularly important for downstream communities and ecosystems that depend on the river's flow.
