Overview
San Lorenzo wastewater treatment plant serves 46,649 people in Ciudad de México, Mexico. It operates under Mexico's national water regulations for urban wastewater management.
San Lorenzo is a wastewater treatment plant located in the Tláhuac borough of Ciudad de México, Mexico. It serves a population of approximately 46,649 people, placing it in the medium agglomeration category for urban wastewater treatment. As a plant in Mexico, San Lorenzo is subject to the country's federal water laws, including NOM-001-SEMARNAT-1996 and NOM-002-SEMARNAT-1996, which set discharge limits for pollutants. The plant discharges treated wastewater into the local drainage system, which ultimately flows into the Valley of Mexico basin. This basin is a closed hydrological system, meaning water does not naturally drain to the sea, making water quality management critical for the region's lakes and groundwater resources.
Environmental context
The plant's treated effluent enters the Valley of Mexico basin, an endorheic basin that historically contained Lake Texcoco. Today, the basin's water bodies include Lake Xochimilco and Lake Chalco, which support diverse aquatic life and are important for local biodiversity. The closed basin means pollutants can accumulate, making effective treatment essential for protecting these sensitive water bodies and the surrounding ecosystem.
