ETE Salitre Wastewater Treatment Plant, Salitre, Ceará, Brazil

ETE Salitre is a municipal wastewater treatment plant located in Salitre, a municipality in the state of Ceará, Brazil. The plant serves a population of 1,974 residents, providing secondary-level treatment to domestic wastewater. It is situated in the semi-arid region of northeastern Brazil, an area characterized by seasonal droughts and limited water resources. The plant operates with secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. For a small agglomeration of under 2,000 people, secondary treatment meets the basic requirements under Brazilian environmental regulations, which are aligned with international standards for wastewater management. The plant's discharge volume is reported at 68.26 cubic meters, indicating a modest flow consistent with its service population. The treated effluent from ETE Salitre is discharged into local water bodies that ultimately drain into the Jaguaribe River basin, one of the most important river systems in Ceará. The Jaguaribe River flows eastward to the Atlantic Ocean, supporting agriculture, drinking water supplies, and aquatic ecosystems. Proper treatment at ETE Salitre helps protect downstream water quality in this water-stressed region.

ETE Salitre discharges into the Jaguaribe River basin, which drains into the Atlantic Ocean via the Jaguaribe River. The region's semi-arid climate means surface water is scarce and ecologically sensitive. The plant's secondary treatment reduces organic pollution, safeguarding downstream aquatic life and supporting water reuse for irrigation in a basin where water conservation is critical.
