Ciudad Eten Wastewater Treatment Plant - Etén, Lambayeque, Peru

Ciudad Eten is a wastewater treatment plant located in Etén, within the Lambayeque region of Peru. The facility serves a population of about 23,801, placing it in the medium agglomeration category for the region. Peruvian wastewater treatment plants are regulated under national environmental standards, including the General Environmental Law and sector-specific regulations for water and sanitation. For plants of this scale, secondary treatment is typically required to reduce organic load and protect receiving waters. The plant discharges into local water bodies that ultimately drain into the Pacific Ocean. The Lambayeque region features coastal ecosystems and agricultural areas that depend on water quality. Proper treatment helps safeguard downstream environments, including nearshore marine habitats and irrigation water sources.

The plant's discharge likely enters the Chancay River or a tributary, flowing through the Lambayeque valley before reaching the Pacific Ocean near the city of Chiclayo. This coastal region supports diverse aquatic life and is important for local fisheries and agriculture. Maintaining treatment standards helps protect these downstream ecosystems from nutrient pollution and pathogens.
