Overview
ETE LAGOA AREA 14 is a secondary treatment plant serving 2,708 people in Manaus, Amazonas, Brazil. It discharges 324.77 m³/day of treated wastewater into the local watershed.
ETE LAGOA AREA 14 is a municipal wastewater treatment plant located in Manaus, the capital of Amazonas state in northern Brazil. The plant serves a population of approximately 2,708 people, placing it in the small agglomeration category under Brazilian water quality standards. It operates in the heart of the Amazon rainforest, a region of immense ecological importance. The plant provides secondary treatment, which is the standard level required for urban wastewater in Brazil under CONAMA Resolution 430/2011 and the National Basic Sanitation Plan (PLANSAB). Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. As part of the Amazon basin, the plant's discharge ultimately flows into the Amazon River system, which drains into the Atlantic Ocean. The surrounding region is characterized by tropical rainforest climate and high biodiversity. Proper wastewater treatment is critical to protect the sensitive aquatic ecosystems of the Amazon, including its rivers, floodplains, and downstream habitats.
Environmental context
The plant is located in Manaus, within the Amazon River basin, the largest river system in the world by discharge volume. Treated effluent from the plant eventually reaches the Amazon River, which flows into the Atlantic Ocean. The region supports diverse aquatic life, including fish species that migrate through the river system, and the surrounding rainforest plays a key role in global carbon and water cycles. Protecting water quality in this watershed is essential for maintaining ecological balance and supporting local communities.
