Overview
ETE CRISTALINA is a municipal wastewater treatment plant serving Cristalina, Goiás, Brazil. It operates under Brazil's national water quality regulations, treating wastewater for approximately 11,000 residents.
ETE CRISTALINA is a municipal wastewater treatment plant located in Cristalina, Goiás, Brazil, along Rodovia Presidente Juscelino Kubitschek. The plant serves a population of approximately 10,969 people, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. As a facility in Brazil, ETE CRISTALINA is subject to the National Environmental Council (CONAMA) resolutions and the National Water Resources Policy (Law 9.433/1997). Brazilian regulations require wastewater treatment for urban areas, with standards for effluent quality based on the receiving water body classification. For a plant of this scale, secondary treatment is typically expected to meet biochemical oxygen demand (BOD) and total suspended solids (TSS) limits. The plant discharges into local watercourses that drain into the Paraná River basin, which flows through southeastern Brazil and eventually into the Río de la Plata estuary. The region's Cerrado biome is ecologically significant, supporting diverse aquatic life and acting as an important water source for agriculture and urban areas downstream.
Environmental context
The plant's treated effluent enters local streams that are part of the Paraná River basin, one of South America's largest drainage systems. The Cerrado savanna ecosystem surrounding Cristalina is a biodiversity hotspot, with seasonal rainfall patterns influencing water availability and quality. Downstream, the Paraná River supports extensive wetlands and floodplains that provide critical habitat for fish and migratory birds.
