ETE NOSSO TETO_VILA GUARNIERI - Colina, São Paulo Wastewater Treatment Plant

ETE NOSSO TETO_VILA GUARNIERI is a wastewater treatment plant located in Colina, within the state of São Paulo, Brazil. The plant serves a population of approximately 13,701 people, classifying it as a medium-sized agglomeration under Brazilian wastewater management standards. As a facility in Brazil, the plant operates under the national regulatory framework established by the Ministry of Cities and state environmental agencies such as CETESB in São Paulo. Brazilian regulations require secondary treatment for urban wastewater, with more stringent standards for discharges into sensitive water bodies. It is expected to meet the secondary treatment standards typical for its population tier. The plant discharges treated effluent into local water bodies that drain into the Rio Grande basin, part of the Paraná River system. This river system ultimately flows into the Río de la Plata estuary, supporting diverse aquatic ecosystems and providing water for agriculture and communities downstream.

The plant's treated effluent enters local streams that flow into the Rio Grande, a major tributary of the Paraná River. The Paraná River system drains into the Río de la Plata estuary, which supports a rich biodiversity including migratory fish species and wetland habitats. The region's tropical climate and agricultural land use make proper wastewater treatment essential to prevent nutrient pollution and protect downstream water quality.
