ETE Estoril Ponta Pora Wastewater Treatment Plant, Ponta Porã, Brazil

ETE Estoril Ponta Pora is a wastewater treatment plant located in the Jardim Estoril neighborhood of Ponta Porã, in the state of Mato Grosso do Sul, Brazil. The plant serves a population of approximately 13,040 residents, placing it in the category of a medium-sized agglomeration under Brazilian wastewater management frameworks. As a facility operating in Brazil, the plant is subject to national regulations including CONAMA Resolution 430/2011 and the National Basic Sanitation Plan (PLANSAB), which set effluent discharge standards and treatment requirements. The plant discharges into local watercourses that ultimately drain into the Paraná River basin, a major hydrological system in South America. The receiving waters support diverse aquatic life and are important for regional agriculture and water supply. Proper treatment at this facility helps protect downstream ecosystems and water quality in the broader Paraná watershed.

The plant's treated effluent flows into local streams that are part of the Paraná River basin, one of the largest river systems in South America. The Paraná River drains into the Río de la Plata estuary, supporting diverse aquatic habitats including wetlands and floodplains that are critical for fish spawning and migratory bird species. The region's tropical climate and agricultural land use make nutrient management particularly important to prevent eutrophication in downstream water bodies.
