Environmental context
The plant's discharge contributes to the Paraguacu River basin, which flows into Todos os Santos Bay, a large tropical bay on Brazil's northeastern coast. This bay supports diverse marine life, including mangroves and fish species, and is an important area for local fisheries. Proper treatment helps protect these downstream ecosystems from nutrient pollution and pathogens.
