Overview
28 de Julio is a secondary wastewater treatment plant in Aguas Verdes, Tumbes, Peru, serving about 10,500 people. It discharges 864 m³/day of treated effluent near the Pacific coast.
28 de Julio is a wastewater treatment plant located in Aguas Verdes, a town in the Zarumilla Province of the Tumbes Region in northern Peru. The plant serves a population of approximately 10,500 residents and operates with secondary treatment, which is typical for medium-sized agglomerations in the region. Peru's wastewater treatment regulations are overseen by the National Superintendence of Sanitation Services (SUNASS) and the Ministry of Housing, Construction and Sanitation. For plants of this scale, secondary treatment is the standard to reduce organic load and pathogens before discharge. The plant's daily discharge volume of 864 m³ indicates a moderate flow consistent with the population served. The treated effluent from 28 de Julio likely drains into the Zarumilla River basin, which flows into the Pacific Ocean near the border with Ecuador. This coastal area supports mangrove ecosystems and estuarine habitats that are sensitive to nutrient loading and pollution. Proper treatment is essential to protect marine biodiversity and local fisheries.
Environmental context
The plant discharges into the Zarumilla River watershed, which flows into the Pacific Ocean near the Peru-Ecuador border. This coastal region includes mangrove forests and estuarine environments that provide critical habitat for fish, crustaceans, and migratory birds. Nutrient and pathogen removal through secondary treatment helps reduce eutrophication risks and protects downstream marine ecosystems.
