ETE Quixelô Wastewater Treatment Plant - Quixelô, Ceará, Brazil

ETE Quixelô is a municipal wastewater treatment facility located in Quixelô, a city in the state of Ceará, northeastern Brazil. The plant serves a population of approximately 4,683 residents, reflecting its role in managing domestic wastewater for a small urban community. As part of Brazil's sanitation infrastructure, it contributes to public health and environmental protection in the region. The plant operates with secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. This level of treatment is appropriate for a community of this size and aligns with Brazilian regulatory standards for wastewater discharge. The plant processes an average daily flow of 529.63 cubic meters, indicating consistent operation within its designed capacity. The treated effluent is discharged into local water bodies that ultimately drain into the Jaguaribe River basin, a major hydrological system in Ceará. This river flows eastward to the Atlantic Ocean, supporting diverse aquatic life and providing water for agriculture and human consumption. By treating wastewater to secondary standards, ETE Quixelô helps protect downstream water quality and ecosystem health.

The plant discharges into the Jaguaribe River basin, which is the largest river system in Ceará and flows into the Atlantic Ocean near the city of Aracati. This watershed supports a variety of aquatic species and is important for regional water supply and irrigation. The secondary treatment process reduces organic pollutants, helping to maintain water quality in the river and its downstream estuary, which is ecologically sensitive due to its role as a nursery for fish and crustaceans.
