ETE PONTAL SP - Pontal, São Paulo Wastewater Treatment Plant

ETE PONTAL SP is a municipal wastewater treatment plant located in Pontal, within the state of São Paulo, Brazil. It serves a population of approximately 41,239 people, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. The plant is situated in the Ribeirão Preto region, an area known for its agricultural and industrial activity. Brazilian wastewater treatment plants are regulated under federal environmental standards (CONAMA resolutions) and state-level agencies such as CETESB in São Paulo. For agglomerations of this size, secondary treatment is typically required to reduce organic load and protect receiving waters. It operates within a regulatory framework that mandates compliance with discharge standards. The treated effluent from ETE PONTAL SP is discharged into local water bodies that drain into the Pardo River basin, which eventually flows into the Paraná River system. This river network supports diverse aquatic life and provides water for agriculture and urban use downstream. Proper treatment is essential to prevent nutrient pollution and maintain water quality in this ecologically sensitive region.

The plant discharges into the Pardo River basin, a tributary of the Paraná River system, which ultimately drains into the Río de la Plata estuary. This watershed supports diverse aquatic ecosystems and is important for regional water supply. The area's agricultural activities make nutrient management critical to prevent eutrophication in downstream water bodies.
