Overview
ETE ICo is a municipal wastewater treatment plant serving Icó, Ceará, Brazil. It treats wastewater from approximately 18,582 residents in the semi-arid Northeast region.
ETE ICo is a municipal wastewater treatment plant located in Icó, a city in the state of Ceará, Brazil. The plant serves a population of approximately 18,582 people, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment standards are governed by federal regulations such as CONAMA Resolution 430/2011, which sets effluent quality parameters. The plant discharges treated effluent into local water bodies within the Jaguaribe River basin, which flows through the semi-arid sertão region of Ceará. The Jaguaribe River is a critical water source for agriculture and human consumption, eventually draining into the Atlantic Ocean near Aracati. Proper treatment at ETE ICo helps protect downstream water quality and supports the ecological health of this important basin.
Environmental context
ETE ICo discharges into the Jaguaribe River basin, the largest river system in Ceará, which flows eastward to the Atlantic Ocean. The semi-arid climate means water resources are scarce, making the river vital for irrigation, livestock, and municipal supply. Downstream, the Jaguaribe estuary supports diverse aquatic life and is an important migratory corridor for birds. Effective wastewater treatment is essential to prevent nutrient loading and maintain water quality in this sensitive ecosystem.

Brazil's wastewater treatment is regulated by CONAMA Resolution 430/2011, which sets effluent quality standards. Plants serving populations like Icó are typically required to provide secondary treatment to meet discharge limits and protect receiving water bodies.
For agglomerations of around 18,000 people, Brazilian regulations generally mandate secondary treatment, such as activated sludge or stabilization ponds, to reduce organic load and pathogens before discharge into rivers like the Jaguaribe.
