Hydraulic Engineering for the Environment

80% of the world's water discharge – mainly located within urban centres – is not adequately treated before it is released into the environment again. Water pollution is expected to be the main cause for water shortage in the near future, together with climate change. Salini Impregilo is also active in this field, where it builds infrastructure that collects, channels and treats waste water from large urban centres, improving the quality of water in receptive water bodies (usually rivers or seas), reducing pollution and making water resources available for new uses, like irrigation.
