Secondary treatment typically involves biological processes to remove organic matter and suspended solids, ensuring the effluent meets quality standards before discharge. The plant treats an average daily flow of 302.40 cubic meters. The treated effluent is discharged into local water bodies, contributing to the protection of downstream ecosystems. The plant plays a key role in maintaining water quality in the Paraná River basin, which ultimately drains into the Río de la Plata estuary. By reducing pollutant loads, ETE Suruquá helps preserve aquatic habitats and supports regional water resource management.

The plant discharges into local streams that feed into the Paraná River basin, one of South America's major river systems. The Paraná River flows southward through Brazil, Paraguay, and Argentina, eventually reaching the Río de la Plata estuary. This watershed supports diverse aquatic life and is important for regional biodiversity. The secondary treatment provided by ETE Suruquá helps reduce organic pollution and nutrient loads, mitigating impacts on downstream water quality and ecological health.
