Periodistas de Mexico Wastewater Treatment Plant, León, Guanajuato

Periodistas de Mexico is a wastewater treatment plant located in León, Guanajuato, Mexico. The plant provides secondary treatment, which is a standard biological process for reducing organic matter and suspended solids. As a secondary treatment plant in Mexico, it operates under the national water quality regulations (NOM-001-SEMARNAT-1996 and subsequent updates), which set discharge limits for pollutants. The designed capacity suggests it can handle a population equivalent larger than currently served, indicating potential for future growth or seasonal variations. The plant's treated effluent is discharged into the local watershed, which is part of the Lerma-Santiago-Pacific hydrological system. This system drains into the Pacific Ocean via the Lerma River and Lake Chapala. The plant plays a role in protecting water quality in the region, which supports agriculture and ecosystems downstream.

The plant discharges into the Lerma River basin, which flows into Lake Chapala, Mexico's largest freshwater lake, and eventually reaches the Pacific Ocean. The watershed supports diverse aquatic life and is important for irrigation and drinking water. The plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in downstream water bodies.
