ETE Jose Carlos Pierocetti - Secondary Wastewater Treatment Plant in Satuba, Alagoas

ETE Jose Carlos Pierocetti is a wastewater treatment plant located in Satuba, within the state of Alagoas in northeastern Brazil. The plant serves a small population of 1,684 residents, reflecting its role in a smaller community. Its location near the coast places it in a sensitive environmental zone where treated effluent management is critical. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. The plant's discharge volume of 124.35 units indicates ongoing operations. Under Brazilian regulations, wastewater treatment plants are subject to national standards set by CONAMA resolutions, which mandate treatment levels based on receiving water body sensitivity and population served. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the nearby coastal lagoons and rivers. The proximity to the coast means that the plant's discharge can affect marine ecosystems, including mangroves and estuarine habitats that support diverse aquatic life. Proper treatment is essential to protect these sensitive environments from nutrient pollution and other contaminants.

The plant discharges into the coastal watershed of Alagoas, which flows into the Atlantic Ocean via the Mundaú-Manguaba lagoon complex. This estuarine system supports mangroves, fish nurseries, and migratory bird species. The proximity to the coast increases the risk of nutrient enrichment and algal blooms if treatment is inadequate, highlighting the need for effective secondary treatment to protect downstream marine biodiversity.
