Overview
ETE Santa Cruz das Palmeiras serves approximately 29,461 people in São Paulo, Brazil. The plant operates under Brazil's national wastewater regulations for medium-sized agglomerations.
ETE Santa Cruz das Palmeiras is a municipal wastewater treatment plant located in Santa Cruz das Palmeiras, within the state of São Paulo, Brazil. The facility serves a population of around 29,461 residents, classifying it as a medium-sized agglomeration under Brazilian wastewater management standards. Brazil's wastewater treatment framework, governed by the National Environmental Council (CONAMA) and state environmental agencies, requires appropriate treatment levels based on receiving water body sensitivity and population size. For plants of this scale, secondary treatment is typically mandated to reduce organic load and suspended solids before discharge. The plant's treated effluent is discharged into local watercourses that drain into the Rio Pardo basin, part of the larger Paraná River system. This watershed supports diverse aquatic ecosystems and provides water for agricultural and urban uses downstream. Proper treatment at this facility helps protect water quality in the region's rivers and reservoirs.
Environmental context
The plant discharges into tributaries of the Rio Pardo, which flows into the Rio Grande and ultimately the Paraná River basin. This watershed supports important aquatic habitats and is used for irrigation and drinking water supply. The region's tropical climate with seasonal rainfall can affect dilution capacity, making consistent treatment essential for maintaining downstream ecological health.
