CLEAN WATER AND SANITATION

Ensure access to water and sanitation for all

Over 2,000 million people in the world live without access to a basic drinking water service, and 3,6 billionhave no access to a basic sanitation service, resulting in avoidable deaths, chronic disease, fewer hours of education and low productivity.

ACCIONA has positioned itself as a key player in the water treatment sector. Its innovative management seeks to resolve the challenges with respect to the shortage of water resources.

 

CLIMATE ACTION

Take urgent action to combat climate change and its impacts

The generation and use of energy accounts for  35 % of total greenhouse gas emissions in the world. This activity is the largest contributor to global warming. Investment in renewable energy, energy efficiency and other low-carbon technologies will continue to be essential to meet the emerging needs of humanity and to minimize their negative impact on the environment.

ACCIONA considers the fight against climate change and its effects to be a strategic priority. The company works to mitigate greenhouse gas emissions in order to contribute to the progress of society and respond to the main challenges of sustainable development in the areas of infrastructure, water and energy, leading the transition to a low-carbon economy.

The Bilbao Bizkaia Water Consortium awarded ACCIONA the contract to improve the performance of the DWTP, the second most important of all the consortium's water supply facilities, as it supplies the municipalities of Durango, Iurreta, Mañaria Izurza, Elorrio, Zaldibar and Ermua.

The Garaizar DWTP had only one decanter, which prevented important maintenance and conservation work from being carried out properly, since it cannot be taken out of service for more than a few hours. The project has managed to provide it with an additional decanter to increase quality guarantees, in addition to other improvements to leave a completely renovated facility to adequately fulfill its function over the next few years.
