ETE LOURDES is a municipal wastewater treatment plant located in Lourdes, a small town in the state of São Paulo, Brazil. The plant serves a population of about 1,775 residents, reflecting its role in a small agglomeration. It operates in the Região Imediata de Birigui-Penápolis, part of the broader Araçatuba region in southeastern Brazil. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. For small communities in Brazil, secondary treatment is typical under national regulations, which align with general environmental standards for inland and coastal discharges. Likely cubic meters per day or similar), indicating a modest flow consistent with its population served. The treated wastewater is discharged into a receiving water body near the coast, as the plant is within 10 km of the coastline. This proximity to the Atlantic Ocean means the effluent must meet stringent quality standards to protect coastal ecosystems. The plant plays a key role in safeguarding downstream water bodies, including rivers and estuaries that drain into the South Atlantic, supporting local biodiversity and water quality.
Environmental context
The plant discharges into a water body that ultimately drains to the Atlantic Ocean via the coastal watershed of São Paulo state. This region features a mix of agricultural and urban areas, with rivers and streams flowing through the Atlantic Forest biome. The coastal zone supports diverse aquatic life, including fish and crustaceans, and is an important area for migratory species. Effective treatment at ETE LOURDES helps reduce nutrient and pollutant loads, protecting downstream estuarine and marine habitats from eutrophication and contamination.
