Camargo Wastewater Treatment Plant, Ciudad Camargo, Tamaulipas

Camargo wastewater treatment plant is located in Ciudad Camargo, Tamaulipas, Mexico, serving a population of approximately 7,905 residents. The facility is part of the municipal wastewater infrastructure for this border region near the Rio Grande. As a small-scale treatment plant in Mexico, Camargo operates under the national water regulatory framework administered by CONAGUA (Comisión Nacional del Agua). Mexican regulations require basic treatment for municipal wastewater, with standards aligned to NOM-001-SEMARNAT-1996 for discharge quality. Plants of this size typically employ primary or secondary treatment processes to meet effluent limits. The treated effluent from Camargo ultimately drains into the Rio Grande basin, which flows into the Gulf of Mexico. This waterway is ecologically significant as a major river system supporting diverse aquatic habitats and providing water resources for communities on both sides of the US-Mexico border. The plant's operation helps protect downstream water quality in this sensitive transboundary watershed.

Camargo's treated wastewater discharges into the Rio Grande basin, which flows southeastward to the Gulf of Mexico. The Rio Grande is a critical water source for arid and semi-arid regions, supporting riparian ecosystems and migratory bird routes. Downstream, the river forms the border between Texas and Tamaulipas, where water quality is essential for both human use and aquatic life, including species such as the Rio Grande silvery minnow.
