El Tamarindo Wastewater Treatment Plant, Tamarindo, Piura, Peru

El Tamarindo wastewater treatment plant is located in the town of Tamarindo, within the Paita province of the Piura region in northwestern Peru. The plant serves a population of approximately 5,135 residents, placing it in the small agglomeration category. It is situated in a coastal desert climate zone, where water resources are scarce and treatment is critical for environmental protection. Under Peruvian regulations, wastewater treatment plants are governed by the Ministry of Housing, Construction and Sanitation (MVCS) and the National Water Authority (ANA). For small agglomerations like El Tamarindo, primary or secondary treatment is typically required to meet effluent standards before discharge. The plant operates within the framework of Peru's national sanitation policy, which aims to expand coverage and improve treatment quality. The plant's treated effluent likely discharges into a local watercourse that flows toward the Pacific Ocean, given its proximity to the coast (within 50 km). The Piura region is characterized by seasonal rivers that drain into the Pacific, supporting agricultural activities and coastal ecosystems. Proper treatment helps protect downstream water quality and marine habitats.

The plant is located in the Piura region, an arid coastal area where rivers such as the Piura and Chira drain into the Pacific Ocean. The receiving water body is likely a seasonal stream or irrigation canal that eventually reaches the Pacific. The coastal waters off Piura support important fisheries and marine biodiversity, including the Illescas Reserved Zone and the Sechura Bay ecosystem. Effective wastewater treatment is essential to prevent nutrient loading and pathogen contamination that could harm these sensitive marine environments.
