ETE Pontalina Wastewater Treatment Plant - Pontalina, Goiás, Brazil

ETE Pontalina is a wastewater treatment plant located in Pontalina, a municipality in the state of Goiás, Brazil. The plant serves a population of approximately 14,407 people, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment framework is governed by the National Environmental Council (CONAMA) and state-level environmental agencies. For communities of this scale, secondary treatment is typically required to meet effluent standards before discharge into receiving water bodies. The regulatory context ensures that appropriate treatment levels are mandated. The plant discharges into local watercourses that drain into the Paranaíba River basin, part of the larger Paraná River system. This region is characterized by agricultural activity and seasonal rainfall patterns, making effective wastewater treatment important for protecting downstream water quality and aquatic ecosystems.

ETE Pontalina discharges into the Paranaíba River basin, which flows into the Paraná River and ultimately reaches the Río de la Plata estuary. The local watershed supports diverse aquatic life and is important for regional agriculture and water supply. Effective treatment helps maintain water quality in this ecologically sensitive river system.
