ETE DALBo is a wastewater treatment facility located in the Mariland district of Caxias do Sul, in the state of Rio Grande do Sul, Brazil. The plant serves a population of about 3,725 residents, placing it in the small agglomeration category under Brazilian wastewater management frameworks. The plant provides secondary treatment, which is the standard level required by Brazilian regulations (CONAMA Resolution 430/2011) for most inland water bodies. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant discharges an average of 557.28 cubic meters of treated wastewater daily. The treated effluent from ETE DALBo is released into local watercourses that are part of the Taquari-Antas River basin, which ultimately drains into the Lagoa dos Patos lagoon system and then the Atlantic Ocean. This watershed supports diverse aquatic life and is important for regional water supply and agriculture.
Environmental context
The plant discharges into the Taquari-Antas River basin, which flows into the Lagoa dos Patos, one of the largest coastal lagoons in South America. This lagoon system is ecologically sensitive, supporting diverse fish populations and migratory birds. The watershed also provides water for irrigation and industrial use in the region, making proper wastewater treatment essential for maintaining water quality and ecosystem health.
