ETE JARDIM NOLI - Secondary Wastewater Treatment Plant in Guaíba, Brazil

ETE JARDIM NOLI is a municipal wastewater treatment facility located in Guaíba, a city in the metropolitan region of Porto Alegre, Rio Grande do Sul, Brazil. The plant provides secondary treatment for a small population of 938 residents, contributing to local sanitation infrastructure in the Região Sul. As a secondary treatment plant, ETE JARDIM NOLI meets the basic standard for organic matter removal required under Brazilian environmental regulations (CONAMA Resolutions). For small agglomerations like this, secondary treatment is typically sufficient to protect receiving water quality. The plant discharges a daily volume of 95.04 cubic meters of treated effluent. The treated effluent from ETE JARDIM NOLI likely flows into local watercourses that drain into the Guaíba River, which then empties into the Lagoa dos Patos, a large coastal lagoon in southern Brazil. This lagoon is an ecologically important system supporting diverse aquatic life and fisheries. Being within 10 km of the coast, the plant's discharge ultimately reaches the Atlantic Ocean, making proper treatment essential to prevent nutrient enrichment and protect coastal ecosystems.

The plant's discharge enters local streams that feed the Guaíba River, which flows into the Lagoa dos Patos, one of the largest coastal lagoons in the world. This lagoon is a critical habitat for fish, birds, and other wildlife, and supports important fisheries. The proximity to the Atlantic Ocean (within 10 km) means that nutrients and pollutants from the plant could affect coastal water quality and marine ecosystems if treatment is inadequate.
