ETE CRATEUS 10 - Secondary Wastewater Treatment Plant in Crateús, Ceará

ETE CRATEUS 10 is a municipal wastewater treatment plant located in Crateús, a city in the state of Ceará within Brazil's Nordeste region. The plant serves a population of approximately 3,518 residents, providing essential sanitation services to this semi-arid area. The plant operates with secondary treatment, which is appropriate for its scale. Under Brazil's national environmental regulations, including CONAMA resolutions, secondary treatment is the standard for municipal wastewater to reduce organic load and pathogens before discharge. The plant's discharge volume is recorded at 285.12 cubic meters per day. The treated effluent from ETE CRATEUS 10 is discharged into local water bodies that drain into the Poti River basin, eventually reaching the Parnaíba River and the Atlantic Ocean. This plant plays a key role in protecting water quality in a region characterized by seasonal droughts and sensitive aquatic ecosystems.

The plant's discharge enters local streams that flow into the Poti River, a tributary of the Parnaíba River, which ultimately reaches the Atlantic Ocean. The semi-arid climate of Ceará means water resources are scarce and ecologically sensitive, making effective wastewater treatment critical to maintaining water quality for downstream communities and aquatic life.
