Spanish-based company Acciona Agua has completed construction and announced the opening of the wastewater treatment plant and underwater outlet of La Chira in Lima, Peru.


The €97M project will treat the wastewater of about 3M people, representing around one-third of the population of Peru’s capital city.

The plant features an advanced system to neutralise bad odours through biological bacterial treatment, reducing the atmospheric pollution created by the traditional use of chemicals in this kind of process.

The plant is to be operated under a 25-year concession by a joint venture led by Acciona Agua and Graña y Montero.
