ETE RANCHO MUNDO Wastewater Treatment Plant, Corbélia, Paraná, Brazil

ETE RANCHO MUNDO is a wastewater treatment plant located in Corbélia, within the state of Paraná, Brazil. The plant serves a population of around 3,295 residents, providing secondary-level treatment as part of the municipal sanitation infrastructure. It operates under Brazil's national environmental regulations, which set standards for effluent quality and water resource protection. The plant employs secondary treatment processes, which involve biological degradation of organic matter, reducing pollutants before discharge. The plant's discharge volume of approximately 986.69 cubic meters indicates its operational scale. Brazilian regulations for wastewater treatment, such as CONAMA resolutions, guide the required treatment levels and discharge limits for facilities of this size. The treated effluent from ETE RANCHO MUNDO is released into local water bodies that drain into the Paraná River basin, a major hydrological system in South America. This basin supports diverse aquatic ecosystems and is vital for agriculture, industry, and drinking water supplies downstream. Proper treatment helps protect water quality and ecological health in the region.

The plant discharges into local streams that flow into the Paraná River basin, which ultimately reaches the Río de la Plata estuary. This watershed supports diverse aquatic life, including fish species important for local fisheries. Effective secondary treatment reduces organic load and nutrients, mitigating eutrophication risks in downstream water bodies.
