ETE SAO JOAO TRES LAGOAS - Wastewater Treatment Plant in Três Lagoas, Brazil

ETE SAO JOAO TRES LAGOAS is a wastewater treatment plant located in the Jupiá district of Três Lagoas, in the state of Mato Grosso do Sul, Brazil. The plant serves a population of 7,328, placing it in the small agglomeration category under Brazilian wastewater management frameworks. As a small-scale facility, the plant is expected to meet secondary treatment standards as per Brazilian regulations (CONAMA Resolution 430/2011), which mandate minimum treatment levels for all municipal wastewater discharges. The plant discharges into the local watershed, which ultimately drains into the Paraná River basin, one of South America's major river systems. The Paraná River flows southward through Brazil, Paraguay, and Argentina, eventually reaching the Río de la Plata estuary. The plant's operations contribute to protecting water quality in this ecologically significant basin, which supports diverse aquatic life and is important for regional water supply and agriculture.

The plant is located in the Paraná River basin, a major South American watershed that drains into the Río de la Plata estuary. The receiving water body is likely a tributary of the Paraná River, which flows through the Atlantic Forest and Cerrado biomes, supporting diverse aquatic species and providing critical habitat for migratory fish. The region's tropical climate and agricultural activities make effective wastewater treatment essential to prevent nutrient loading and maintain downstream water quality.
