Victoria Wastewater Treatment Plant - Guanajuato, Mexico

The Victoria wastewater treatment plant is located in the town of Victoria, within the state of Guanajuato, Mexico. It serves a population of around 8,084 people, classifying it as a small to medium agglomeration under Mexican wastewater regulations. The plant is situated in an inland area, away from coastal zones, and its operations are part of the municipal infrastructure managed by local authorities. As a facility serving fewer than 10,000 inhabitants, the Victoria plant is subject to Mexico's national wastewater standards (NOM-001-SEMARNAT-1996 and subsequent updates), which set discharge limits for pollutants based on the receiving water body's classification. Plants of this scale typically employ secondary treatment technologies such as activated sludge or stabilization ponds to meet regulatory requirements. The treated effluent from the Victoria plant is discharged into local watercourses that ultimately drain into the Lerma River basin, one of Mexico's most important hydrological systems. The Lerma River flows westward into Lake Chapala, the largest freshwater lake in Mexico, before continuing to the Pacific Ocean. The plant's operations play a role in protecting downstream water quality and supporting the ecological health of the Lerma-Chapala basin.

The Victoria plant discharges into tributaries of the Lerma River, which flows into Lake Chapala, a critical freshwater resource for the region. The Lerma-Chapala basin supports diverse aquatic life and provides water for agriculture, industry, and human consumption. Protecting this watershed from untreated wastewater is essential for maintaining water quality and ecosystem services downstream.
