Posope Alto Wastewater Treatment Plant, Pátapo, Lambayeque, Peru

Posope Alto is a wastewater treatment plant located in Pátapo, within the Chiclayo province of the Lambayeque region in Peru. The facility serves an estimated population of 15,724, placing it in the medium agglomeration category for the region. As a Peruvian treatment plant, Posope Alto operates under the national regulatory framework for wastewater management, which includes standards for effluent quality and environmental protection. For a plant of this scale, secondary treatment is typically required to reduce organic load and suspended solids before discharge. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Pacific Ocean via the Chancay-Lambayeque River system. This river basin supports agricultural activities and provides water for nearby communities, making proper treatment essential for protecting both human health and downstream ecosystems.

Posope Alto discharges into the Chancay-Lambayeque River basin, which flows through the Lambayeque region before reaching the Pacific Ocean. The river supports irrigation for local agriculture and sustains aquatic habitats. Downstream, the river's delta and coastal zone are ecologically sensitive areas that rely on good water quality for biodiversity and fisheries.
