ETE Angelica II Wastewater Treatment Plant, Angelica, Mato Grosso do Sul

ETE Angelica II is a wastewater treatment facility located in Angelica, Mato Grosso do Sul, Brazil. The plant serves a small population of approximately 500 residents, reflecting its role in a rural or small-town setting within the state's interior. Its location along MS-141 places it within the broader drainage network of the Parana River basin. The plant provides secondary treatment, which is the standard biological treatment level required under Brazilian regulations (CONAMA resolutions) for municipal wastewater. This level typically involves biological processes to reduce organic matter and suspended solids. For small agglomerations like this, secondary treatment is generally sufficient to meet environmental standards. The treated effluent likely discharges into a local watercourse that eventually flows into the Parana River system, one of South America's major river basins. This river system supports diverse aquatic life and provides water for agriculture and communities downstream. Proper treatment at plants like ETE Angelica II helps protect water quality in the region's streams and rivers, which are important for both ecological health and human use.

The plant's discharge enters a local tributary within the Parana River basin, which flows into the Parana River and ultimately reaches the Rio de la Plata estuary. This watershed supports diverse aquatic ecosystems, including fish species that rely on clean water for spawning and migration. The region's tropical climate and agricultural land use make effective wastewater treatment essential to prevent nutrient pollution and protect downstream water quality.
