ETE JACUI SAO MATEUS Wastewater Treatment Plant, São Mateus, Brazil

ETE JACUI SAO MATEUS is a municipal wastewater treatment plant located in the Residencial Jacuí neighborhood of São Mateus, in the state of Espírito Santo, Brazil. The plant serves a small population of 888 residents and operates with secondary treatment, which is typical for smaller communities in the region. Its location in the Região Sudeste places it within a densely populated and economically active area of Brazil. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a discharge volume of 72.01 (likely in cubic meters per day or similar unit), the facility meets the basic treatment requirements for its scale. Brazilian wastewater regulations, such as CONAMA resolutions, set effluent standards for such plants to protect water quality. The treated effluent is discharged into local water bodies that eventually reach the Atlantic Ocean, given the plant's proximity to the coast (within 10 km). This coastal discharge requires careful management to prevent nutrient enrichment and protect marine ecosystems. The plant plays a role in safeguarding the health of downstream waters and the coastal environment of Espírito Santo.

The plant discharges into local streams that flow into the Atlantic Ocean near São Mateus, a coastal city in Espírito Santo. The receiving waters support diverse aquatic life and are part of a regionally important coastal ecosystem. Nutrient and pathogen removal from secondary treatment helps reduce the risk of eutrophication and protects downstream habitats, including mangroves and estuaries that are ecologically sensitive.
