Overview
ETE Vila Rica in Santa Bárbara d'Oeste, São Paulo, Brazil, is a primary treatment plant serving 444 people. It discharges 86.40 m³/day of treated wastewater into the local watershed.
ETE Vila Rica is a wastewater treatment plant located in Santa Bárbara d'Oeste, within the state of São Paulo, Brazil. The plant serves a small population of 444 residents, reflecting its role in a localized community. It is situated in the Região Metropolitana de Campinas, an area with significant industrial and agricultural activity. The plant provides primary treatment, which involves physical processes like sedimentation to remove solids. For a facility of this scale, primary treatment is a basic level of processing. Under Brazilian regulations, smaller plants may have less stringent requirements, but the plant contributes to reducing pollutant loads before discharge. The treated effluent is discharged into the local watershed, which ultimately drains into the Piracicaba River basin, a key water resource in the region. This river flows into the Tietê River, which passes through São Paulo state and eventually reaches the Paraná River basin. The plant helps protect downstream water quality in this ecologically and economically important system.
Environmental context
The plant discharges into the Piracicaba River basin, which flows into the Tietê River, a major waterway in São Paulo state. The Tietê River ultimately joins the Paraná River, draining into the Río de la Plata estuary. This watershed supports diverse aquatic life and provides water for agriculture, industry, and drinking water for millions. Primary treatment reduces but does not fully remove nutrients, so downstream eutrophication risks exist, especially in slower-moving sections.
