Corrales Wastewater Treatment Plant, Pampa San Isidro, Tumbes, Peru

Corrales is a secondary-level wastewater treatment plant located in Pampa San Isidro, within the Corrales district of Tumbes, Peru. The facility serves a population of approximately 5,241 people and discharges an average of 432 cubic meters of treated wastewater per day. Its location near the Panamericana Norte highway places it within the coastal region of northern Peru. As a secondary treatment plant, Corrales provides biological treatment to reduce organic matter and suspended solids, meeting the standard requirements for municipal wastewater in Peru. The plant operates under Peru's national water quality regulations, which align with general Latin American standards for urban wastewater management. For a community of this size, secondary treatment is the typical prescribed level to protect public health and the environment. The treated effluent from Corrales ultimately reaches the Pacific Ocean via local drainage channels and the Tumbes River basin. The coastal waters off Tumbes support diverse marine life, including important fisheries and mangrove ecosystems. Proper treatment at this plant helps reduce nutrient and pathogen loads that could otherwise impact nearshore water quality and the ecological health of the region's coastal habitats.

Corrales plant discharges into the Tumbes River basin, which flows into the Pacific Ocean near the Gulf of Guayaquil. This coastal zone supports mangrove forests and estuarine habitats that are critical for fish and bird species. The plant's secondary treatment helps mitigate nutrient pollution that could otherwise contribute to algal blooms and oxygen depletion in the sensitive nearshore marine environment.
