Angostura Limon Wastewater Treatment Plant, Subtanjalla, Ica, Peru

Angostura Limon is a wastewater treatment plant located in Subtanjalla, within the Ica region of Peru. The facility serves a population of approximately 36,690 people, placing it in the medium agglomeration category. It is situated inland, away from the coast, and its operations are part of the municipal wastewater infrastructure for the area. In Peru, wastewater treatment plants are regulated under national environmental standards, which require appropriate treatment levels based on the receiving water body and population served. For medium-sized agglomerations, secondary treatment is typically expected to protect water quality. The treated effluent from Angostura Limon likely discharges into local watercourses that drain into the Pacific Ocean via the Ica River basin. The region's arid climate and reliance on irrigation make proper wastewater treatment crucial for protecting both human health and the fragile desert ecosystem. Downstream water bodies support agricultural activities and local biodiversity.

The plant is located in the Ica region, a coastal desert area in southern Peru. Treated wastewater likely flows into the Ica River or its tributaries, which drain into the Pacific Ocean. The downstream environment includes agricultural zones and sensitive coastal habitats that depend on adequate water quality. Proper treatment helps prevent nutrient pollution and protects marine life in the Pacific.
