Overview
ETE Petropoils is a secondary wastewater treatment plant serving 271 people in Manaus, Amazonas, Brazil. It discharges 32.48 m³/day of treated effluent into the local watershed.
ETE Petropoils is a municipal wastewater treatment facility located in Manaus, the capital of Amazonas state in northern Brazil. The plant serves a small population of 271 residents, reflecting its role in a localized area of the city. Manaus is situated in the heart of the Amazon rainforest, a region characterized by high rainfall and dense tropical ecosystems. The plant provides secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. Secondary treatment is the standard requirement under Brazilian environmental regulations (CONAMA resolutions) for wastewater facilities of this scale. The plant's discharge volume is 32.48 m³/day, indicating a modest operational capacity. The treated effluent is released into the local drainage network, which ultimately flows into the Amazon River basin. The Amazon River system is the largest river basin in the world, supporting immense biodiversity and critical ecosystem services. Proper wastewater treatment is essential to protect water quality in this sensitive environment, where untreated sewage can harm aquatic life and human health.
Environmental context
The plant discharges into the Amazon River basin, the world's largest river system by volume, which drains into the Atlantic Ocean. The surrounding watershed supports diverse aquatic life, including fish species that are vital for local fisheries and indigenous communities. Protecting water quality in this region is crucial to maintain ecological balance and prevent eutrophication in downstream waters.
