Overview
ETE BACIA BACIA COHAB is a secondary wastewater treatment plant in Quixadá, Ceará, Brazil, serving approximately 4,732 people. It discharges treated effluent into local water bodies.
ETE BACIA BACIA COHAB is a municipal wastewater treatment facility located in the COHAB neighborhood of Quixadá, in the state of Ceará, northeastern Brazil. The plant serves a population of about 4,732 residents, making it a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for most urban wastewater. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent from the plant is released into local waterways that drain into the Sertão region's intermittent rivers, eventually reaching the Jaguaribe River basin. This basin is ecologically important for the semi-arid Caatinga biome, supporting diverse aquatic life and providing water for agriculture and human consumption. Proper treatment helps protect downstream water quality and ecosystem health.
Environmental context
The plant discharges into local streams that are part of the Jaguaribe River basin, the largest river system in Ceará. The Jaguaribe flows eastward to the Atlantic Ocean, passing through the semi-arid Caatinga region. This watershed supports critical habitats for fish and migratory birds, and its waters are used for irrigation and drinking water supply. Effective wastewater treatment is essential to prevent nutrient pollution and maintain water quality in this water-stressed region.
