ETE Florania Wastewater Treatment Plant, Florania, Rio Grande do Norte

ETE Florania is a municipal wastewater treatment plant located in Florania, a city in the state of Rio Grande do Norte, Brazil. The plant serves a population of approximately 7,076 people, classifying it as a small agglomeration under Brazilian sanitation standards. It is situated along BR-226 in the Northeast region of the country. The plant provides secondary treatment, which is the standard level required by Brazilian regulations for urban wastewater before discharge. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a reported discharge volume of 471.55 cubic meters per day, indicating its operational scale. The treated effluent is discharged into local water bodies that eventually drain into the Atlantic Ocean via the Piranhas-Açu river basin. The region's semi-arid climate makes water quality management particularly important for downstream communities and ecosystems. The plant plays a key role in protecting local water resources from untreated sewage pollution.

The plant's discharge enters the Piranhas-Açu river basin, which flows through the semi-arid Caatinga biome before reaching the Atlantic Ocean. This watershed supports diverse aquatic life and is critical for local agriculture and drinking water supplies. The Caatinga ecosystem is highly sensitive to water quality changes, and the plant's secondary treatment helps mitigate nutrient and pathogen loads that could harm downstream habitats.
