San Jacinto Wastewater Treatment Plant, Durango, Mexico

The San Jacinto wastewater treatment plant is located in the city of San Jacinto, within the municipality of Lerdo, Durango, Mexico. This facility serves a small population of 913 residents, reflecting its role in a rural or semi-urban community. The plant is part of Mexico's national wastewater infrastructure, which is regulated under the Ley de Aguas Nacionales and operated by local water authorities. The plant employs secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 1123.20 volume units and an actual discharge volume of 86.40 units, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. As a small-scale facility, it aligns with typical treatment expectations for communities of this size in Mexico. The treated effluent is discharged into local water bodies, likely contributing to the hydrological network of the Nazas River basin, which drains into the Laguna de Mayran and ultimately the Gulf of Mexico. The plant's operation helps protect downstream ecosystems and water quality in this arid region of northern Mexico.

The plant discharges into the Nazas River basin, which flows through the arid landscapes of Durango and Coahuila before reaching the Laguna de Mayran, an important wetland and migratory bird habitat. Downstream, the basin drains into the Gulf of Mexico, supporting diverse aquatic life and regional agriculture. The secondary treatment reduces organic pollutants, safeguarding water quality in this water-scarce region.
