The plant's operational details, including specific treatment processes and capacity, are part of the broader municipal sanitation plan for Altinópolis. The treated effluent from ETE Altinópolis is discharged into local water bodies that drain into the Rio Pardo basin, eventually reaching the Paraná River system and the Río de la Plata estuary. This watershed supports diverse aquatic life and is important for regional water supply and agriculture. Proper treatment at this plant helps protect downstream ecosystems and water quality.

The plant's discharge enters local streams that flow into the Rio Pardo, a tributary of the Rio Grande, which is part of the Paraná River basin. This watershed ultimately drains into the Río de la Plata estuary, a major ecological zone supporting diverse fish species and migratory birds. The region's tropical climate and agricultural activity make effective wastewater treatment crucial for preventing nutrient pollution and maintaining water quality in downstream water bodies.
