Overview
ETE URUOCA is a secondary wastewater treatment plant in Uruoca, Ceará, Brazil, serving approximately 2,221 people. It discharges treated effluent into local water bodies, supporting sanitation in the semi-arid Nordeste region.
ETE URUOCA is a municipal wastewater treatment plant located in Uruoca, a municipality in the state of Ceará, Brazil. The plant serves a population of about 2,221 people, placing it in the small-agglomeration category. It operates in the semi-arid climate of the Nordeste region, where water resources are scarce and treatment is critical for public health and environmental protection. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for most inland discharges. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant's design and operation align with national norms for small communities. The treated effluent is discharged into local water bodies that drain into the Atlantic Ocean via the Acaraú River basin. The region's intermittent rivers and reservoirs make wastewater treatment essential for preserving water quality for downstream uses, including agriculture and domestic supply. The plant contributes to reducing pollution loads in a water-stressed environment.
Environmental context
The plant discharges into the Acaraú River basin, which flows through Ceará's semi-arid landscape before reaching the Atlantic Ocean. This region experiences seasonal droughts, making water quality management critical for aquatic life and human use. The treated effluent helps protect downstream ecosystems, including estuarine areas that support diverse fish and bird species.
Frequently asked questions
ETE URUOCA is located at Rua Olga Belarmino in Uruoca, a municipality in the state of Ceará, Brazil. It serves the urban area of Uruoca.
The plant serves approximately 2,221 people, making it a small-scale wastewater treatment facility for the local community.
The plant provides secondary treatment before discharging the effluent into local water bodies within the Acaraú River basin. The treated water eventually flows to the Atlantic Ocean.
Brazilian wastewater treatment plants operate under CONAMA resolutions and state-level environmental permits. For small agglomerations like Uruoca, secondary treatment is typically required to meet effluent standards for organic matter and suspended solids.
For small communities in Brazil, secondary treatment is standard, often using technologies like stabilization ponds, anaerobic reactors, or activated sludge. The choice depends on local conditions, but the goal is to reduce biochemical oxygen demand and protect receiving water bodies.
