This lagoon is an ecologically important coastal ecosystem that supports diverse aquatic life and is a critical habitat for migratory birds and fish species.

The plant discharges into the Jacuí River basin, which flows into the Lagoa dos Patos, one of the largest coastal lagoons in South America. This lagoon system supports a rich biodiversity, including fish, crustaceans, and migratory birds, and is vital for local fisheries. Proper wastewater treatment is essential to prevent nutrient pollution and maintain the ecological health of this downstream environment.
