Malabrigo Wastewater Treatment Plant, Rázuri, La Libertad, Peru

Malabrigo is a wastewater treatment plant located in the port town of Puerto Malabrigo, within the district of Rázuri in the Ascope province of La Libertad, Peru. The plant serves a population of approximately 3,613 people, reflecting a small coastal community. As a Peruvian wastewater facility, Malabrigo operates under the national regulatory framework overseen by the Superintendencia Nacional de Servicios de Saneamiento (SUNASS) and the Ministry of Housing, Construction and Sanitation. For small agglomerations like this, secondary treatment is typically required to meet effluent standards before discharge. The plant's proximity to the coast (within 50 km) suggests that treated wastewater likely reaches the Pacific Ocean, either directly or via a nearby watercourse. Given its coastal location, the treated effluent probably discharges into the Pacific Ocean or a coastal stream that flows into the sea. This area supports marine biodiversity and artisanal fisheries, making proper treatment essential to protect coastal water quality and ecosystem health.

Malabrigo lies near the Pacific coast of northern Peru, within the Sechura Desert ecoregion. The nearest major river is the Chicama River, which flows into the Pacific Ocean south of the plant. The coastal waters off La Libertad support important fisheries, including anchoveta and other pelagic species. Discharge from the plant, if not adequately treated, could impact nearshore marine habitats and local fishing grounds. The region's arid climate means limited dilution capacity in receiving waters, emphasizing the need for effective treatment to prevent nutrient enrichment and pathogen contamination.
