ETE JAGUARAO is a municipal wastewater treatment plant located in Jaguarão, a city in the state of Rio Grande do Sul, Brazil. The plant serves a population of approximately 12,973 residents, placing it in the medium agglomeration category. It is situated in the southern region of Brazil, near the border with Uruguay, and operates within the local water management framework. The plant's designed capacity is 1.00 cubic meter per second, indicating a moderate scale of operation. As a Brazilian wastewater facility, it is subject to national regulations under the National Environmental Council (CONAMA) and state-level environmental agencies. The treated effluent from ETE JAGUARAO is discharged into local water bodies that ultimately drain into the Patos Lagoon system, a large coastal lagoon connected to the Atlantic Ocean. This watershed supports diverse aquatic life and is important for regional fisheries and water quality. The plant plays a key role in protecting the local environment by reducing pollutant loads before discharge.

The plant discharges into the Jaguarão River basin, which flows into the Patos Lagoon, one of the largest coastal lagoons in South America. The lagoon supports a rich ecosystem, including migratory fish species and waterbirds, and is a critical nursery habitat for marine life. Protecting water quality in this watershed is essential for maintaining the ecological health of the Patos Lagoon and the adjacent Atlantic coastal zone.
