ETE CORUMBAIBA - Secondary Wastewater Treatment Plant in Corumbaíba, Goiás, Brazil

ETE CORUMBAIBA is a municipal wastewater treatment plant located in Corumbaíba, a city in the state of Goiás, Brazil. The plant serves a population of about 6,400 people, making it a small-scale facility within the region's sanitation infrastructure. It operates under Brazil's national environmental regulations, which set effluent quality standards for secondary treatment. The plant provides secondary treatment, a standard level for communities of this size in Brazil. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant discharges approximately 950 cubic meters of treated wastewater per day, reflecting its capacity to handle the local domestic load. The treated effluent is released into a local watercourse that ultimately drains into the Paraná River basin, a major hydrological system in South America. This discharge contributes to the maintenance of water quality in downstream ecosystems, supporting aquatic life and regional water availability. The plant plays a key role in preventing untreated sewage from entering the environment, thereby protecting public health and local biodiversity.

The treated effluent from ETE CORUMBAIBA flows into a tributary of the Paraná River basin, which drains into the Paraná River and eventually reaches the Río de la Plata estuary. The local watershed supports diverse aquatic habitats and is important for agriculture and water supply in the region. The plant's secondary treatment helps reduce nutrient and organic pollution, mitigating eutrophication risks in downstream water bodies.
