ETE MASSAPE CE - Wastewater Treatment Plant in Massapê, Ceará, Brazil

ETE MASSAPE CE is a wastewater treatment plant located in Massapê, a municipality in the state of Ceará, Brazil. The plant serves a population of about 8,800 people, classifying it as a small to medium agglomeration under Brazilian sanitation standards. It is situated along Rodovia Senador Osires Pontes in the Mumbaba neighborhood. The plant provides secondary treatment, which is the minimum standard required by Brazilian regulations (CONAMA 430/2011) for most inland discharges. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is released into local water bodies that drain into the Atlantic Ocean via the Acaraú River basin. This region of Ceará is semi-arid, making water quality management critical for local ecosystems and downstream communities. The plant plays a key role in protecting the Acaraú River and its tributaries from untreated sewage pollution.

The plant discharges into the Acaraú River basin, which flows northward through Ceará and empties into the Atlantic Ocean near the city of Acaraú. The downstream environment includes coastal mangroves and estuaries that support diverse aquatic life, including fish and crustaceans important for local fisheries. Protecting this watershed from nutrient pollution is essential for maintaining water quality and ecosystem health in the semi-arid region.
