San Bartolo Morelos Wastewater Treatment Plant, Estado de México, Mexico

San Bartolo Morelos is a wastewater treatment plant located in the municipality of Morelos, Estado de México, Mexico. It serves a population of approximately 10,559 residents, making it a small-scale municipal facility. The plant is situated inland, away from coastal areas, and its operations are part of the local water infrastructure managed by state and municipal authorities. As a plant serving a small agglomeration, it is subject to Mexican official standards (NOM-001-SEMARNAT) which set discharge limits for pollutants based on the receiving water body. Typical facilities of this scale employ primary or secondary treatment to meet regulatory requirements. Its population served suggests a modest treatment volume. The treated effluent is discharged into local watercourses that eventually drain into the Lerma River basin, a major hydrological system in central Mexico. The Lerma River flows into Lake Chapala, Mexico's largest freshwater lake, which supports diverse aquatic life and provides water for irrigation and human consumption. Protecting this watershed is critical for regional water quality and ecosystem health.

The plant discharges into the Lerma River basin, which flows into Lake Chapala, a vital freshwater resource in central Mexico. The lake supports a rich ecosystem of fish and migratory birds and is a key water source for surrounding communities. Maintaining low pollutant loads is essential to prevent eutrophication and protect biodiversity in this sensitive lacustrine environment.
