San Juan de la Virgin Wastewater Treatment Plant, Tumbes, Peru

San Juan de la Virgin wastewater treatment plant is located in San Juan de La Virgen, within the Tumbes region of northern Peru. The facility serves a population of approximately 10,483 residents, classifying it as a medium-sized agglomeration under Peruvian wastewater management standards. The plant operates with secondary treatment, which is the standard required by Peruvian regulations for communities of this scale. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant is situated within 10 kilometers of the Pacific coast, making its discharge potentially influential on coastal water quality. The Tumbes region is characterized by tropical dry forests and mangrove ecosystems, which are sensitive to nutrient inputs. The treated effluent ultimately drains into the Pacific Ocean, contributing to the marine environment of the northern Peruvian coast.

The plant's discharge enters the local watershed, which flows through the Tumbes region and eventually reaches the Pacific Ocean. The coastal area supports diverse marine life, including fish and crustacean populations important for local fisheries. Mangrove ecosystems along the coast are particularly sensitive to nutrient loading and require careful management of treated wastewater to prevent eutrophication.
