Met Mex PeNoles Wastewater Treatment Plant, Torreón, Coahuila, Mexico

Met Mex PeNoles is a wastewater treatment plant located in Torreón, Coahuila, Mexico, serving an estimated population of 100,400. The plant is situated in the arid northern region of Mexico, where water resources are critical for both urban and industrial use. As a facility in a large agglomeration, it plays a key role in managing municipal wastewater for the city of Torreón. The plant's designed capacity is 1.00 (units unspecified), indicating a relatively small-scale facility. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and must comply with official standards (NOM-001-SEMARNAT-1996) for discharge quality. The plant discharges into local water bodies within the Nazas River basin, which flows into the Laguna District and eventually the Rio Grande system. The region's semi-arid climate means that treated wastewater is a valuable resource for agricultural reuse and maintaining ecological flows. Protecting downstream water quality is essential for local communities and ecosystems that depend on these limited water sources.

The plant is located in the Nazas River basin, which drains into the Laguna District and ultimately connects to the Rio Grande. This watershed supports agricultural irrigation and provides habitat for migratory birds and native aquatic species. The arid climate makes water quality management critical for sustaining both human use and ecological health in the region.
