ETE COHAB IGREJINHA Wastewater Treatment Plant, Taquara, Rio Grande do Sul

ETE COHAB IGREJINHA is a municipal wastewater treatment facility located in the Cruzeiro do Sul neighborhood of Taquara, within the Metropolitan Region of Porto Alegre, Rio Grande do Sul, Brazil. The plant serves a population of 2,739 residents, classifying it as a small-scale treatment facility under Brazilian sanitation standards. The plant provides secondary treatment, which is the minimum standard required by Brazilian regulations (CONAMA Resolution 430/2011) for most inland water bodies. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The treated effluent from ETE COHAB IGREJINHA is discharged into local watercourses that drain into the Sinos River basin, a major tributary of the Jacuí River system. The Sinos River is ecologically significant, supporting diverse aquatic life and providing water for downstream communities. The plant's operation helps protect water quality in this important watershed, which ultimately flows into the Patos Lagoon estuary.

The plant discharges into local streams that feed the Sinos River, a key waterway in the Jacuí River basin. The Sinos River supports diverse aquatic ecosystems and is used for water supply, recreation, and agriculture. Downstream, the river flows into the Patos Lagoon, a large coastal lagoon that is an important nursery for fish and migratory birds. Protecting water quality in this basin is critical for maintaining ecological balance and human uses.
