Punta Hermosa Wastewater Treatment Plant | Coastal Lima, Peru

The Punta Hermosa wastewater treatment plant is located in the coastal district of Punta Hermosa, part of the Lima Metropolitan Area in Peru. The plant serves a population of approximately 10,500 residents, providing essential sanitation services for this growing community along the Pacific coast. The plant operates with secondary treatment, which is the standard level required under Peruvian regulations for municipal wastewater. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids before discharge. The plant handles an average daily flow of 864 cubic meters. The treated effluent is discharged into the Pacific Ocean, as the plant is situated within 10 kilometers of the coast. This discharge contributes to the marine environment of the Peruvian coastal zone, which supports diverse marine life including fisheries and seabird populations. Proper treatment is critical to protect coastal water quality and the ecological health of the adjacent marine ecosystem.

The plant discharges into the Pacific Ocean along the central coast of Peru, a region characterized by the cold Humboldt Current that supports rich marine biodiversity, including anchoveta, seabirds, and marine mammals. The coastal waters near Punta Hermosa are part of a productive upwelling zone, making water quality management essential for sustaining local fisheries and tourism. The plant's secondary treatment helps reduce organic pollution and nutrient loading to the marine environment.
