Ixtenco Wastewater Treatment Plant, Ixtenco, Tlaxcala, Mexico

The Ixtenco wastewater treatment plant is located in the town of Ixtenco, in the state of Tlaxcala, Mexico. It serves a population of 8,520 and operates with secondary treatment, which is typical for smaller agglomerations in the region. The plant has a designed capacity of 959.04 cubic meters per day and currently discharges 836.35 cubic meters of treated wastewater daily. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is required for municipal wastewater to meet discharge standards for organic matter and suspended solids. For plants serving populations under 10,000, this level of treatment is generally adequate to protect receiving water bodies, provided proper operation and maintenance are maintained. The treated effluent from the Ixtenco plant is discharged into local watercourses that drain into the Balsas River basin, which ultimately flows into the Pacific Ocean. The region's watershed supports agricultural activities and diverse aquatic life, making proper wastewater treatment essential for maintaining water quality and ecosystem health.

The Ixtenco plant discharges into local streams that are part of the Balsas River basin, one of Mexico's major river systems. The Balsas River flows southwest through several states before emptying into the Pacific Ocean near Lázaro Cárdenas, Michoacán. The watershed supports irrigated agriculture and provides habitat for native fish species and migratory birds. Effective wastewater treatment is critical to prevent nutrient loading and protect downstream water quality in this ecologically and economically important basin.
