Overview
ETE Maragogipe is a wastewater treatment plant serving Santiago do Iguape in Cachoeira, Bahia, Brazil. It treats wastewater for approximately 15,703 people and is located within 50 km of the coast.
ETE Maragogipe is a wastewater treatment plant located in Santiago do Iguape, part of the municipality of Cachoeira in Bahia, Brazil. The plant serves a population of approximately 15,703 people, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. It operates within the Recôncavo Baiano region, an area known for its historical and environmental significance. Brazil's wastewater treatment standards are governed by national regulations, including CONAMA resolutions and the National Sanitation Plan (PLANSAB). For plants of this scale, secondary treatment is typically required to reduce organic load and pathogens before discharge. The plant's treated effluent likely discharges into local water bodies that drain into the Baía de Todos os Santos, one of Brazil's largest and most ecologically important bays. This bay supports diverse aquatic life, including mangroves and fish species, and is a key area for local fisheries and tourism. The proximity to the coast (within 50 km) underscores the importance of effective treatment to protect downstream marine ecosystems.
Environmental context
The plant is situated in the Recôncavo Baiano region, with treated effluent likely flowing into the Paraguaçu River or its tributaries, which empty into the Baía de Todos os Santos. This bay is a large estuarine system supporting mangroves, seagrass beds, and diverse marine life. Effective wastewater treatment is critical to prevent nutrient enrichment and contamination that could harm these sensitive habitats and the local fishing communities that depend on them.
Frequently asked questions
ETE Maragogipe is located in Santiago do Iguape, a district of Cachoeira, in the state of Bahia, Brazil. It serves the local community as part of the municipal wastewater infrastructure.
The plant serves approximately 15,703 people, classifying it as a medium-sized agglomeration under Brazilian wastewater standards.
Treated effluent from the plant is likely discharged into local water bodies that drain into the Paraguaçu River and eventually into Baía de Todos os Santos, a large coastal bay.
The plant operates under Brazilian federal regulations, including CONAMA Resolution 430/2011 for effluent standards and the National Sanitation Plan (PLANSAB), which mandate appropriate treatment levels for population size and receiving water body sensitivity.
For agglomerations of this size, secondary treatment is typically required to reduce biochemical oxygen demand (BOD) and pathogens. Common processes include activated sludge, stabilization ponds, or anaerobic systems, depending on local conditions.
