ETE Pinhalzinho SP is a wastewater treatment plant located in Pinhalzinho, a city in the state of São Paulo, Brazil. The plant serves a population of approximately 5,774 people, making it a small-scale facility within the region's sanitation infrastructure. It is situated in the Jardim Albertina neighborhood, near the Altos do Pinhal subdivision. Brazil's wastewater treatment framework is governed by the National Environmental Council (CONAMA) and the National Water Agency (ANA), which set discharge standards and water quality criteria. For small agglomerations like Pinhalzinho, secondary treatment is typically required to reduce organic load and protect receiving waters. It is expected to comply with CONAMA Resolution 430/2011 for effluent quality. The treated effluent from ETE Pinhalzinho SP is discharged into a local watercourse that flows into the Piracicaba River basin, part of the broader Paraná River system. This basin supports agricultural activities and provides drinking water for downstream communities. Proper treatment is essential to prevent nutrient pollution and maintain the ecological health of the region's rivers.
Environmental context
The plant discharges into a tributary of the Piracicaba River, which flows into the Tietê River and eventually reaches the Paraná River basin. This watershed is ecologically important for the Atlantic Forest region, supporting diverse aquatic life and providing water for irrigation and human consumption. The area is subject to seasonal rainfall patterns, and untreated or inadequately treated wastewater could contribute to eutrophication and sedimentation in downstream water bodies.
