Environmental context
The plant discharges into the coastal watershed of Espírito Santo, likely via tributaries of the Santa Maria da Vitória River or directly into Vitória Bay, which opens to the Atlantic Ocean. This estuarine and coastal environment supports mangroves, fish nurseries, and migratory bird species. Nutrient loading from untreated or poorly treated wastewater can lead to eutrophication and harm marine biodiversity, making secondary treatment critical for ecosystem health.
