Overview
ETE Caetés is a wastewater treatment plant serving 19,171 people in Abreu e Lima, Pernambuco, Brazil. It lies within 50 km of the coast, discharging into the local watershed near Recife.
ETE Caetés is a wastewater treatment plant located in Abreu e Lima, a municipality in the metropolitan region of Recife, Pernambuco, Brazil. The plant serves a population of approximately 19,171 residents, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. Its location in the coastal zone of northeastern Brazil subjects it to specific environmental regulations regarding effluent discharge and marine protection. Brazilian wastewater treatment plants are regulated under federal resolutions by CONAMA (National Environment Council) and state-level environmental agencies. For agglomerations of this size, secondary treatment is typically required to reduce organic load and suspended solids. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a facility sized for the community's needs. Operational details and treatment process specifics are managed by the municipal or state sanitation company. The plant's discharge ultimately reaches the Atlantic Ocean via the local drainage network, which includes rivers and estuaries in the Recife metropolitan area. This coastal region supports mangroves, estuaries, and diverse aquatic life, making proper treatment essential to prevent eutrophication and protect marine ecosystems. The proximity to densely populated areas and industrial zones adds to the environmental significance of the plant's performance.
Environmental context
ETE Caetés discharges into the watershed of the Recife metropolitan region, which drains into the Atlantic Ocean via the Capibaribe and Beberibe rivers and their estuaries. This coastal zone features sensitive mangrove ecosystems and estuarine habitats that support fish, crustaceans, and migratory birds. Proper wastewater treatment is critical to prevent nutrient loading and contamination that could harm these ecologically important areas.
Frequently asked questions
ETE Caetés is located in Abreu e Lima, a city in the metropolitan region of Recife, Pernambuco, Brazil. Its address is Quadra Caetés 3, Rua Quarenta, Vila Miguel Arraes, Caetés III.
The plant serves approximately 19,171 people, classifying it as a medium-sized agglomeration under Brazilian wastewater standards.
The plant discharges treated effluent into the local watershed, which flows through rivers and estuaries in the Recife metropolitan area before reaching the Atlantic Ocean.
Brazilian wastewater treatment plants are regulated by CONAMA resolutions and state environmental agencies. Plants serving populations over 10,000 typically require secondary treatment to meet organic load and suspended solids standards.
For agglomerations of this size, secondary treatment is standard, often using activated sludge or lagoon systems to reduce biochemical oxygen demand and protect receiving water bodies.
