ETE Horto Park Wastewater Treatment Plant, Lauro de Freitas, Bahia

ETE Horto Park is a wastewater treatment plant located in Lauro de Freitas, within the Metropolitan Region of Salvador, Bahia, Brazil. The plant serves a small population of 1,359 residents, reflecting its role in a localized community within the broader urban area. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. In Brazil, wastewater treatment regulations are guided by CONAMA resolutions and state-level environmental agencies, which set discharge standards for such facilities. For a plant of this scale, secondary treatment is typical and meets basic environmental requirements. The treated effluent is discharged into the local environment, likely into a water body that drains into the Atlantic Ocean, given the plant's proximity to the coast (within 10 km). This coastal location means the discharge can affect marine ecosystems, including mangroves and coastal waters that support diverse aquatic life and local fisheries.

The plant is situated near the coast of Bahia, within the Metropolitan Region of Salvador. Its treated effluent likely flows into a local watercourse that drains into the Atlantic Ocean, impacting coastal ecosystems such as mangroves and estuaries. These habitats support diverse marine life and are important for local fisheries and biodiversity. The proximity to the coast necessitates careful management to prevent nutrient enrichment and protect water quality.
