Overview
ETE Complexo 1 serves Penápolis, São Paulo, Brazil, treating wastewater for a population of approximately 41,912. The plant operates under Brazil's national water quality regulations.
ETE Complexo 1 is a municipal wastewater treatment plant located in Penápolis, within the state of São Paulo, Brazil. The facility serves an estimated population of 41,912, placing it in the medium agglomeration category for Brazilian wastewater infrastructure. Its location in the southeastern region of Brazil places it within a densely populated and industrialized area, where water resource management is critical. The plant is expected to comply with Brazil's national environmental standards, including CONAMA Resolution 430/2011, which sets effluent discharge limits. For a plant of this scale, secondary treatment is typical to meet regulatory requirements for organic matter and nutrient removal. The designed capacity is reported as 1.00, though the unit is unspecified, indicating a need for contextual interpretation. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Paraná River basin, one of South America's largest river systems. This basin supports extensive agriculture, hydroelectric power, and biodiversity. Proper treatment at ETE Complexo 1 helps protect downstream water quality in the Tietê River and eventually the Paraná River, which flows into the Río de la Plata estuary.
Environmental context
The plant's treated effluent enters the local drainage network within the Paraná River basin, a major South American watershed that drains into the Río de la Plata estuary. This basin supports diverse aquatic ecosystems and is vital for regional water supply, agriculture, and hydropower. Downstream water bodies include the Tietê River, which flows through São Paulo state and is ecologically sensitive due to urban and industrial inputs. Effective treatment at ETE Complexo 1 helps mitigate nutrient loading and organic pollution, preserving aquatic habitat and water quality for downstream communities.
