EPC Maceió Wastewater Treatment Plant - Maceió, Alagoas, Brazil

EPC Maceió is a wastewater treatment plant located in Maceió, the capital of Alagoas state in northeastern Brazil. The plant serves a population of approximately 239,000 residents, placing it in the category of a medium-to-large agglomeration under Brazilian wastewater regulations. It is situated in the Prado neighborhood along Avenida Assis Chateaubriand, near the coast. Brazil's national wastewater standards, established by CONAMA Resolution 430/2011 and the National Basic Sanitation Plan (PLANSAB), require secondary treatment for urban wastewater. As a plant serving over 200,000 people, EPC Maceió is expected to meet these standards to protect public health and the environment. The plant's designed capacity is 1.00 cubic meter per second, indicating a significant infrastructure investment. The plant's treated effluent ultimately reaches the Atlantic Ocean, likely through local rivers or drainage channels. Maceió's coastal location means the discharge affects nearshore marine ecosystems, including coral reefs and mangroves that support diverse aquatic life. Proper treatment is critical to prevent nutrient pollution and protect the region's tourism-dependent coastal waters.

EPC Maceió discharges into the Atlantic Ocean via local water bodies in the coastal region of Alagoas. The receiving waters include nearshore marine environments that support coral reefs, seagrass beds, and mangrove forests, which are ecologically sensitive habitats. These ecosystems provide nursery grounds for fish and protect the coastline from erosion. The plant's operation is crucial for maintaining water quality in the urbanized coastal zone of Maceió.
