San Bartolome Zoogocho is a wastewater treatment plant located in the municipality of San Bartolomé Zoogocho, Oaxaca, Mexico. The plant serves a small community of 548 people, reflecting its role in a rural setting within the Sierra Norte region of Oaxaca. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants before discharge. The plant has a designed capacity of 259.20 cubic meters per day and currently treats an average of 51.84 cubic meters daily, indicating a utilization rate of about 20%. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is the standard for municipal wastewater, ensuring compliance with discharge limits for biochemical oxygen demand and total suspended solids. The treated effluent is discharged into local water bodies that ultimately drain into the Papaloapan River basin, which flows into the Gulf of Mexico. The plant's operation helps protect downstream aquatic ecosystems and supports water quality in the region, which is known for its biodiversity and indigenous communities.
Environmental context
The plant discharges into local streams that are part of the Papaloapan River basin, one of Mexico's major river systems. The Papaloapan River flows through Oaxaca and Veracruz before emptying into the Alvarado Lagoon and then the Gulf of Mexico. This watershed supports diverse aquatic life and is important for local fisheries and agriculture. The secondary treatment provided by the plant helps reduce nutrient and organic loading, mitigating eutrophication risks in downstream water bodies.
