Overview
Pemex wastewater treatment plant serves Salamanca, Guanajuato, Mexico, with a population of approximately 203,000. It operates under Mexico's national water regulations.
The Pemex wastewater treatment plant is located in Salamanca, Guanajuato, Mexico, serving a population of about 203,000. The facility is situated in an industrial region and plays a key role in managing municipal wastewater for the city. As a large agglomeration serving over 150,000 people, the plant is expected to meet secondary treatment standards under Mexican regulations (NOM-001-SEMARNAT). These standards set discharge limits for pollutants to protect water quality. The plant's capacity and treatment processes are designed to handle the wastewater load from the urban area. The treated effluent is discharged into the local watershed, which ultimately drains into the Lerma River basin. The Lerma River flows into Lake Chapala, Mexico's largest freshwater lake, supporting diverse aquatic ecosystems and providing water for agriculture and communities downstream.
Environmental context
The plant discharges into the Lerma River basin, which flows into Lake Chapala, a critical freshwater resource in central Mexico. The lake supports a variety of fish species and migratory birds, and its health is sensitive to nutrient pollution from upstream sources. Proper treatment at the Pemex plant helps protect this downstream ecosystem.
