ETE Guararapes Wastewater Treatment Plant, Guararapes, São Paulo, Brazil

ETE Guararapes is a wastewater treatment plant located in Guararapes, a municipality in the state of São Paulo, Brazil. The plant serves a population of approximately 29,392 people, placing it in the medium agglomeration category under Brazilian regulatory frameworks. It is situated in the interior of São Paulo state, within the Araçatuba region, and operates as part of the municipal sanitation infrastructure. As a plant serving a medium-sized population, ETE Guararapes is expected to comply with Brazilian national standards for wastewater treatment, which are established by CONAMA resolutions and state-level environmental agencies. These regulations typically require secondary treatment for inland plants to protect water quality in receiving water bodies. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a facility sized for its service area. The treated effluent from ETE Guararapes is discharged into local watercourses that ultimately drain into the Paraná River basin, one of the major river systems in South America. The downstream environment supports diverse aquatic life and provides water for agricultural and urban uses. Proper treatment at this plant helps protect the ecological health of the receiving waters and downstream communities.

The plant discharges into local streams that flow into the Tietê River, a major tributary of the Paraná River basin. The Paraná River system drains into the Río de la Plata estuary, supporting extensive wetlands and diverse aquatic ecosystems. The region's watershed is important for agriculture and biodiversity, and effective wastewater treatment helps prevent nutrient pollution and maintain water quality for downstream users.
