ETE Duas Barras Iconha - Secondary Wastewater Treatment Plant in Iconha, Brazil

ETE Duas Barras Iconha is a wastewater treatment plant located in Iconha, a municipality in the state of Espírito Santo, Brazil. The plant serves a small population of 291 residents, reflecting its role in a small community. It is situated near the coast, within 10 km of the Atlantic Ocean, which influences its environmental considerations. The plant provides secondary treatment, a standard level for small agglomerations in Brazil. Under Brazilian regulations, wastewater treatment is governed by CONAMA resolutions and state-level environmental agencies, which set discharge standards for organic matter and nutrients. For a plant of this scale, secondary treatment is typical and meets basic requirements for protecting water quality. The treated effluent is discharged into a local water body that ultimately drains to the Atlantic Ocean. The coastal location means the discharge can affect nearshore marine ecosystems, including mangroves and estuaries that support diverse aquatic life. Proper treatment helps mitigate impacts on these sensitive environments.

The plant discharges into a local watercourse that flows to the Atlantic Ocean near Iconha, in Espírito Santo. The coastal region features mangroves and estuarine habitats that are ecologically sensitive, supporting fish, crustaceans, and migratory birds. The discharge of treated wastewater must comply with standards to protect these ecosystems from nutrient enrichment and pollution.
