ETE Cristo Rei Ponta Grossa - Secondary Wastewater Treatment Plant in Ponta Grossa, Paraná

ETE Cristo Rei Ponta Grossa is a municipal wastewater treatment plant located in the Cristo Rei neighborhood of Ponta Grossa, Paraná, Brazil. The plant serves a population of 1,540 residents and operates with secondary treatment, a standard level for smaller communities in Brazil. The plant treats an average of 203.90 m³ of wastewater per day. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids, meeting the basic requirements for effluent quality under Brazilian regulations. The plant is part of the municipal sanitation infrastructure managed by the local water authority. The treated effluent is discharged into local water bodies that drain into the Tibagi River basin, which flows through the Paraná state and eventually reaches the Paraná River. The Tibagi River supports diverse aquatic life and is important for regional water supply and agriculture. Proper treatment helps protect downstream water quality and ecosystem health.

The plant discharges into local streams that are part of the Tibagi River watershed. The Tibagi River flows through the Campos Gerais region and eventually joins the Paranapanema River, a major tributary of the Paraná River. This basin supports diverse aquatic ecosystems, including fish species important for local fisheries. The secondary treatment provided by the plant reduces organic pollution, helping to maintain water quality in this ecologically sensitive area.
