ETE Cajueiro Seco Olho D'Agua is a wastewater treatment facility located in the Cajueiro Seco neighborhood of Jaboatão dos Guararapes, within the Recife metropolitan region of Pernambuco, Brazil. The plant serves a small population of around 950 residents, reflecting its role in local sanitation infrastructure. Brazilian wastewater treatment plants are regulated under federal environmental laws, including CONAMA resolutions and state-level permits. For small agglomerations like this, secondary treatment is typically required to reduce organic load and protect water quality. The plant's designed capacity is 1.00 volume unit, indicating a modest scale. The treated effluent likely discharges into local watercourses that flow toward the Atlantic Ocean, given the plant's proximity to the coast (within 50 km). The region's watershed includes rivers draining the Pernambuco coastal plain, supporting estuarine and marine ecosystems. Proper treatment is essential to prevent nutrient pollution and safeguard downstream aquatic life.
Environmental context
The plant is situated in the coastal plain of Pernambuco, within the Recife metropolitan region. Its treated effluent likely enters local streams that flow into the Atlantic Ocean via the Jaboatão River or adjacent estuarine systems. This coastal watershed supports mangroves, fish nurseries, and migratory bird habitats. Nutrient loading from untreated or inadequately treated wastewater can lead to eutrophication and hypoxia in downstream waters, affecting biodiversity and local fisheries.
