Telesecundaria Wastewater Treatment Plant, San Francisco Mitepec, Tlaxcala, Mexico

Telesecundaria is a wastewater treatment plant located in San Francisco Mitepec, a community in the municipality of Españita, Tlaxcala, Mexico. The plant serves a small population of 219 residents, reflecting its role in providing sanitation for a rural agglomeration. As a secondary treatment facility, it employs biological processes to reduce organic matter and suspended solids before discharge. The plant has a designed capacity of 34.56 cubic meters per day and currently treats an average of 20.74 cubic meters per day, indicating it operates below its maximum capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is the standard for municipal wastewater to meet discharge quality criteria. The plant's operation is part of Mexico's national water infrastructure managed by CONAGUA (National Water Commission) and local water utilities. The treated effluent is discharged into local water bodies within the Tlaxcala region, which ultimately drains into the Balsas River basin. The Balsas River flows southwest to the Pacific Ocean, supporting diverse aquatic ecosystems and agricultural activities along its course. The plant's proper operation helps protect downstream water quality and public health in the region.

The plant discharges into local streams that are part of the Balsas River basin, one of Mexico's major hydrological regions. The Balsas River flows through central Mexico and empties into the Pacific Ocean near Lázaro Cárdenas, Michoacán. The watershed supports a variety of aquatic life and provides water for irrigation and domestic use. Downstream ecosystems include riparian habitats and seasonal wetlands that rely on consistent water quality. The plant's secondary treatment helps reduce nutrient loading and organic pollution, which is critical for maintaining the ecological balance of the basin.
