Overview
San Martin wastewater treatment plant serves 26 de Octubre in Piura, Peru, with a designed capacity of 1.00 unit. It operates under Peru's national wastewater regulations for large agglomerations.
San Martin is a wastewater treatment plant located in 26 de Octubre, a district within the Piura region of Peru. The plant serves a population of 209,656, classifying it as a large agglomeration under Peruvian and international standards. Its designed capacity is 1. Peru's wastewater treatment regulations require secondary treatment for urban centers of this scale, with oversight from the National Water Authority (ANA) and the Ministry of Housing, Construction and Sanitation. Plants serving over 100,000 people typically include biological treatment stages to reduce organic load and pathogens before discharge. The plant's treated effluent likely discharges into the Piura River basin, which flows into the Pacific Ocean near the city of Piura. The downstream environment supports agricultural irrigation and local fisheries, making proper treatment essential for public health and ecosystem protection.
Environmental context
The plant is situated inland, more than 50 km from the coast, and its discharge likely enters the Piura River system. The Piura River flows through arid coastal plains before reaching the Pacific Ocean, supporting irrigated agriculture and seasonal wetlands. Downstream ecosystems depend on consistent water quality to sustain fish populations and prevent eutrophication in coastal waters.
