Overview
ETE MARATOAN is a secondary wastewater treatment plant serving 5,426 people in Crateús, Ceará, Brazil. It discharges 439.81 cubic meters of treated effluent daily into local water bodies.
ETE MARATOAN is a municipal wastewater treatment plant located in Crateús, a city in the state of Ceará, northeastern Brazil. The plant serves a population of approximately 5,426 residents, reflecting its role in managing domestic wastewater for a small urban community. It is situated inland, far from the coast, and operates within the semi-arid climate of the Brazilian Northeast region. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazilian regulations (CONAMA resolutions and state environmental laws), secondary treatment is typically required for communities of this size to protect water quality. The plant discharges an average of 439.81 cubic meters of treated wastewater per day, though specific details on the treatment process type or design capacity are not part of this record. The treated effluent is released into local watercourses that drain into the Poti River basin, eventually reaching the Parnaíba River and the Atlantic Ocean. This downstream pathway is ecologically important for sustaining aquatic life and supporting regional water resources in a drought-prone area. Proper treatment helps prevent nutrient pollution and protects downstream ecosystems, including the Parnaíba Delta, a sensitive coastal environment.
Environmental context
The treated effluent from ETE MARATOAN flows into local streams that are part of the Poti River basin, which joins the Parnaíba River before reaching the Atlantic Ocean. The Parnaíba River basin supports diverse freshwater and estuarine habitats, including mangroves and wetlands that are critical for migratory birds and fish. In the semi-arid climate of Ceará, maintaining water quality in these water bodies is essential for both ecological health and human uses such as irrigation and drinking water supply.
