Xochitlaxco Wastewater Treatment Plant, San Baltazar, Puebla, Mexico

The Xochitlaxco wastewater treatment plant is located in the community of San Baltazar, within the municipality of Tepetzintla, in the state of Puebla, Mexico. It serves a population of approximately 1,552 people, making it a small-scale facility focused on local wastewater management. The plant operates with secondary treatment, which is appropriate for its size and typical for small communities in Mexico. The designed capacity is 146.88 volume units, matching the current discharge volume, indicating full utilization. As a Mexican facility, it falls under national water quality regulations administered by CONAGUA (Comision Nacional del Agua), which sets discharge standards to protect water resources. The treated effluent is discharged into local water bodies that eventually drain into the Gulf of Mexico via the Pantepec or Tecolutla river systems. The surrounding region is characterized by mountainous terrain and agricultural land, making proper wastewater treatment essential to prevent contamination of downstream ecosystems and maintain water quality for local communities.

The plant discharges into local streams that are part of the Tecolutla River basin, which flows eastward to the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for agriculture and domestic use. Proper treatment is critical to prevent nutrient pollution and protect downstream ecosystems, including coastal lagoons and mangrove areas near the Gulf.
