Odinsa, a subsidiary of Grupo Argos, is a Colombian company dedicated to the management and development of highway and airport infrastructure projects. ICEACSA and Antea Group Brazil have been collaborating to submit a common proposal for a study of water consumption reduction for road infrastructure and airport concessions of Odinsa in Colombia, Ecuador, Aruba and the Dominican Republic. The study includes 9 Odinsa assets (2 airports, 7 highways), with the purpose of defining goals for water footprint reduction and generating a reduction plan implemented and followed in sustainability reports including GRI and Dow Jones Sustainability Index. The study will be carried out in two stages through diagnostic forms and interviews. The consumption parameterization will be made (m3/passenger, m3/capex, etc.), allowing comparison with other projects. A study of implementation and operation costs will be included to define cost efficiency priority, and based on these conclusions, a reduction plan in three-time horizons will be proposed.
