The companies proposed to charge less to operate the La Chira plant than competing bidders, Proinversion, the government’s private investment promotion agency, said in an e-mailed statement today.
Madrid-based Acciona and Lima-based Grana beat joint bids from Actividades de Construccion y Servicios SA and Comunicaciones y Energia SL, both from Spain; Andrade Gutierrez SA of Brazil and Abengoa SA (ABG/P) of Spain; and Brazil’s Odebrecht SA.
More than 90 percent of the sewage produced in Lima, a city of 8 million people, flows into rivers and the sea without being treated. La Chira will process about one quarter of the city’s waste water before pumping it into the Pacific Ocean through underground pipes, Proinversion said.
“The plant will improve the environment around polluted beach areas,” as well as reduce infections from contact with or consumption of contaminated water, the agency said.
