Overview
ETE Residencial Santa Ines is a secondary treatment plant serving 700 people in Paulo Jacinto, Alagoas, Brazil. It discharges 29.22 units of treated wastewater into the local watershed.
ETE Residencial Santa Ines is a wastewater treatment plant located in Paulo Jacinto, a municipality in the state of Alagoas, Brazil. The plant serves a small population of 700 residents, reflecting its role in a rural or small-town setting within the Northeast Region. It is situated inland, away from coastal areas, and operates under Brazil's national environmental regulations. The plant provides secondary treatment, which is the standard biological treatment required for municipal wastewater in Brazil. This level of treatment removes organic matter and suspended solids, ensuring that the effluent meets basic quality standards before discharge. Brazil's regulatory framework, including CONAMA resolutions, sets discharge limits for parameters such as BOD and TSS, which secondary treatment typically achieves. The treated effluent is discharged into a local water body, likely a river or stream within the São Francisco River basin or a smaller coastal basin in Alagoas. The plant's operation helps protect downstream water quality and supports the ecological health of the region's aquatic ecosystems, which are important for local biodiversity and water supply.
Environmental context
The plant discharges into a local water body within the state of Alagoas, part of the Northeast Region of Brazil. The region's watersheds drain into the Atlantic Ocean, with many rivers supporting diverse aquatic life and providing water for agriculture and communities. The plant's secondary treatment helps reduce nutrient and organic pollution, mitigating impacts on downstream ecosystems and maintaining water quality for sensitive habitats.
