ETE PEDRAS Wastewater Treatment Plant, Fortaleza, Ceará, Brazil

ETE PEDRAS is a wastewater treatment plant located in the Parque Itamaraty neighborhood of Fortaleza, in the state of Ceará, Brazil. It serves a small population of 441 residents, reflecting its role in a localized community within the broader metropolitan area of Fortaleza, one of Brazil's largest cities. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for most inland and coastal discharges. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant treats an average of 54.01 m³ of wastewater per day. Situated less than 10 km from the Atlantic coast, the plant's treated effluent likely discharges into a local watercourse that flows into the Atlantic Ocean. This coastal proximity underscores the importance of effective treatment to protect marine water quality and the diverse ecosystems along the coast of Ceará, including mangroves and estuaries that support fish and bird populations.

The plant is located in Fortaleza, a coastal city in northeastern Brazil, within the Atlantic drainage basin. Treated effluent from the plant likely enters a local stream or canal that flows into the Atlantic Ocean. The coastal waters off Fortaleza support diverse marine life, including coral reefs and sea turtles, and are important for local fisheries and tourism. Proper secondary treatment helps mitigate nutrient and pathogen loading into these sensitive marine environments.
