ETE COTIPORA Wastewater Treatment Plant, Cotiporã, Rio Grande do Sul

ETE COTIPORA is a municipal wastewater treatment plant located in Cotiporã, a city in the state of Rio Grande do Sul, Brazil. The plant serves a population of 1,891 residents, providing secondary treatment to manage domestic wastewater from the community. The plant operates under Brazil's national environmental regulations, which require secondary treatment for urban wastewater. With a population served below 10,000, the facility is classified as a small agglomeration. The treatment process ensures that effluent meets quality standards before discharge. The treated effluent is discharged into local water bodies that ultimately drain into the Jacuí River basin and then into the Lagoa dos Patos lagoon, an important coastal ecosystem. The plant plays a key role in protecting downstream water quality and supporting aquatic life in the region.

The plant discharges into local streams that flow into the Jacuí River, part of the larger Patos Lagoon basin. This lagoon is a major coastal water body in southern Brazil, supporting diverse aquatic species and serving as a critical habitat for migratory birds. The secondary treatment provided by ETE COTIPORA helps reduce nutrient and organic loads, mitigating eutrophication risks in the downstream environment.
