Overview
ETE Sao Silvestre Telemaco Borba is a wastewater treatment plant in Telêmaco Borba, Paraná, Brazil, serving approximately 8,718 people. It operates under Brazil's national water quality regulations.
ETE Sao Silvestre Telemaco Borba is a wastewater treatment facility located in Telêmaco Borba, a city in the state of Paraná, Brazil. The plant serves a population of about 8,718 residents, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment standards are governed by CONAMA Resolution 430/2011 and the National Water Resources Policy (Law 9.433/1997), which set effluent discharge limits and water quality criteria. For plants of this scale, secondary treatment is typically required to meet biochemical oxygen demand (BOD) and total suspended solids (TSS) standards before discharge. The plant's treated effluent likely discharges into a local watercourse within the Paraná River basin, which ultimately flows into the Río de la Plata estuary. The region's aquatic ecosystems support diverse freshwater species, and proper treatment helps maintain water quality in downstream rivers and reservoirs.
Environmental context
The plant is situated inland in Paraná state, within the broader Paraná River basin. Treated wastewater likely enters a tributary of the Tibagi River, which flows into the Paranapanema River and eventually the Paraná River, draining into the Río de la Plata. The downstream environment includes sensitive freshwater habitats that support fish and aquatic biodiversity, making effective nutrient and pathogen removal important for ecological health.
