ETE Morro dos Morenos is a wastewater treatment plant located in the Mambucaba district of Angra dos Reis, in the state of Rio de Janeiro, Brazil. It serves a population of 1,213 people, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for most inland and coastal discharges. With a discharge volume of 184.03 m³/day, the plant operates within the typical scale for a community of this size. Brazilian environmental law mandates that wastewater treatment facilities meet effluent quality standards to protect receiving water bodies. The plant is situated within 10 km of the Atlantic coast, meaning its treated effluent ultimately reaches the ocean, likely via local streams or the nearby Mambucaba River. This coastal proximity necessitates careful management to prevent nutrient loading and protect marine ecosystems, including the adjacent Ilha Grande Bay, a region known for its biodiversity and tourism.
Environmental context
The plant discharges into the Atlantic coastal zone near Ilha Grande Bay, a region of high ecological importance with diverse marine life and mangrove ecosystems. The treated effluent from the plant contributes to the freshwater and nutrient balance of local streams that flow into the bay, which supports fisheries and tourism. Protecting this coastal environment requires effective nutrient removal to avoid eutrophication and maintain water quality for recreational use.
