ETE ITAPERUSSU Wastewater Treatment Plant, Fortaleza, Ceará, Brazil

ETE ITAPERUSSU is a municipal wastewater treatment plant located in the Itaperi neighborhood of Fortaleza, the capital of Ceará state in northeastern Brazil. The plant serves a small population of 285 residents and operates with secondary treatment, which is the minimum standard required under Brazilian regulations (CONAMA Resolution 430/2011) for most inland and coastal discharges. As a secondary treatment facility, ETE ITAPERUSSU uses biological processes to remove organic matter and suspended solids. The plant has a reported discharge volume of 40.99 cubic meters per day, reflecting its small service area. The plant's scale aligns with Brazil's regulatory framework for small agglomerations, which typically requires secondary treatment to protect receiving water quality. The plant is located within 10 km of the Atlantic coast, making its discharge potentially influential on coastal water quality. The treated effluent likely flows into local drainage channels that eventually reach the Atlantic Ocean, contributing to the broader watershed of the Ceará coast. This region supports diverse marine ecosystems, including mangroves and estuaries, which are sensitive to nutrient and pollutant loads from urban runoff and wastewater discharges.

The plant's discharge enters the coastal watershed of Fortaleza, which drains into the Atlantic Ocean via small rivers and urban drainage systems. The nearby coast features sandy beaches and rocky shores that support marine biodiversity, including fish, crustaceans, and migratory birds. Nutrient inputs from treated wastewater can affect local water quality and ecosystem health, particularly in areas with limited tidal flushing.
