La Monera Wastewater Treatment Plant, San Francisco Mitepec, Tlaxcala

La Monera is a municipal wastewater treatment facility located in San Francisco Mitepec, within the municipality of Españita, Tlaxcala, Mexico. The plant serves a small population of 219 residents, reflecting its role in a rural community. It operates under Mexico's national water regulations, which set standards for wastewater treatment and discharge. The plant provides secondary treatment, a standard level for small agglomerations in Mexico. With a designed capacity of 43.20 m³/day and an actual discharge volume of 20.74 m³/day, the facility operates at roughly half its capacity, indicating room for future growth. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, contributing to the regional hydrology. Tlaxcala is an inland state, and the plant's discharge ultimately flows into the Gulf of Mexico via the Pánuco River basin. Proper treatment helps protect downstream aquatic ecosystems and water quality for communities relying on these water resources.

The plant discharges into a local watercourse that is part of the Pánuco River basin, which drains into the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for agriculture and human use in the region. Effective secondary treatment reduces pollutant loads, helping to maintain the ecological health of downstream rivers and coastal waters.
