ETE COHAB MORUMBI - Secondary Wastewater Treatment Plant in Diamantino, Mato Grosso, Brazil

ETE COHAB MORUMBI is a municipal wastewater treatment facility located in Diamantino, Mato Grosso, Brazil. Serving a population of 1,881, it operates as a secondary treatment plant, providing biological treatment to reduce organic matter and suspended solids before discharge. The plant treats approximately 725.70 cubic meters of wastewater per day. As a secondary treatment facility, it meets the standard requirements for Brazilian wastewater treatment, which are regulated by the National Environment Council (CONAMA) and state environmental agencies. For small agglomerations like Diamantino, secondary treatment is the typical level to protect water quality. The treated effluent is discharged into local water bodies, contributing to the preservation of the surrounding watershed. The plant plays a key role in safeguarding public health and the environment in the region, which is part of the broader Cuiabá River basin, ultimately draining into the Paraguay River basin and the Pantanal, one of the world's largest tropical wetlands.

The plant discharges into local streams that flow into the Cuiabá River, a major tributary of the Paraguay River. This river system feeds the Pantanal, a vast floodplain ecosystem of global ecological importance, supporting diverse aquatic life and migratory species. The secondary treatment helps reduce nutrient and organic pollution, protecting downstream water quality and biodiversity.
