Overview
ETE BAIRRO CIDADE ALTA serves Limoeiro do Norte, Ceará, Brazil, treating wastewater for approximately 10,828 residents. The plant operates under Brazil's national environmental regulations.
ETE BAIRRO CIDADE ALTA is a wastewater treatment plant located in Limoeiro do Norte, a municipality in the state of Ceará, Brazil. The plant serves a population of approximately 10,828 people, placing it in the small-to-medium agglomeration category. It is situated inland, more than 50 km from the coast, in the semi-arid Northeast region of Brazil. Brazil's wastewater treatment standards are governed by CONAMA Resolution 430/2011 and the National Basic Sanitation Plan (PLANSAB). For plants of this scale, secondary treatment is typically required to reduce organic load and pathogens. The plant is expected to meet these national discharge standards to protect local water resources. The treated effluent likely discharges into a local watercourse within the Jaguaribe River basin, which flows into the Atlantic Ocean near Fortaleza. The Jaguaribe River is a critical water source for the region, supporting agriculture, drinking water supply, and aquatic ecosystems. Proper treatment at ETE BAIRRO CIDADE ALTA helps maintain water quality in this semi-arid watershed.
Environmental context
The plant is located in the Jaguaribe River basin, the largest river basin in Ceará. The Jaguaribe River flows eastward and discharges into the Atlantic Ocean via the Jaguaribe River estuary, which supports mangroves and diverse aquatic life. The semi-arid climate makes water resources particularly sensitive to pollution, as low flows reduce dilution capacity. Effective wastewater treatment is essential to protect downstream communities and ecosystems that rely on the river for irrigation, fishing, and domestic use.
