Cheel Wastewater Treatment Plant, Córdoba, Veracruz, Mexico

Cheel is a wastewater treatment plant located in Córdoba, Veracruz, Mexico. It serves a population of 2,756 and operates as a secondary treatment facility, which is standard for smaller communities in the region. The plant has a designed capacity of 299.81 cubic meters per day and currently treats 260.93 cubic meters daily. As a secondary treatment plant, Cheel removes organic matter and suspended solids through biological processes. In Mexico, wastewater treatment is regulated by the National Water Commission (CONAGUA) under the Federal Water Rights Law. Plants of this scale are typically required to meet discharge standards for BOD, TSS, and other parameters to protect water quality. The treated effluent is discharged into local water bodies that eventually drain into the Gulf of Mexico. The region's watershed supports diverse aquatic life and is important for agriculture and urban water supply. Proper treatment helps prevent eutrophication and protects downstream ecosystems.

Cheel discharges into the local drainage network of the Jamapa River basin, which flows through the state of Veracruz and empties into the Gulf of Mexico near the port of Veracruz. The river supports a variety of freshwater species and provides water for irrigation and municipal use. The coastal zone is ecologically sensitive, with mangroves and wetlands that rely on balanced freshwater inflows.
