ETE Itamaraju Wastewater Treatment Plant, Itamaraju, Bahia, Brazil

ETE Itamaraju is a municipal wastewater treatment plant located in Itamaraju, Bahia, Brazil, serving an estimated population of 31,979. The plant is situated in the northeastern region of the country, within the Atlantic Forest biome, and operates under Brazil's national environmental regulations, including CONAMA resolutions and state-level licensing from the Bahia environmental agency (INEMA). Plants of this scale in Brazil typically employ secondary treatment technologies such as activated sludge or stabilization ponds to meet effluent standards. The designed capacity of 1.00 (likely in cubic meters per second or similar unit) suggests a facility sized for the local population. Brazilian regulations require adequate treatment to protect water quality in receiving bodies. The plant's treated effluent discharges into local rivers that drain into the Atlantic Ocean, contributing to the health of coastal ecosystems. The region's watershed supports diverse aquatic life and is important for local communities and downstream environments. Proper wastewater treatment helps reduce nutrient loading and pathogen contamination in these sensitive coastal waters.

The plant discharges into local streams that are part of the Atlantic coastal basin, ultimately flowing into the Atlantic Ocean near the coast of Bahia. This region features tropical climate and diverse ecosystems, including mangroves and coral reefs offshore. Effective treatment is crucial to minimize nutrient pollution and protect marine biodiversity in the adjacent coastal waters.
