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.
This drinking water treatment plant (DWTP) will not only provide a service to Tudela but also to the towns of Castejón, Fustiñana, Cabanillas and Fontellas.
The water treated in the plant mostly comes from direct catchment from the River Ebro (6,000,000 m3/year) and is complemented by intake from nearby wells (2,000,000 m3/year). To a lesser extent, and where necessary, it is also possible to take water rom the Canal de Lodosa (10,000 m3/year).
ACCIONA has in-depth knowledge of the DWTP in Tudela as it participated in its construction in 1992, and later (in 2008) in the extension of the plant. The company also undertook the operation and maintenance of the plant from 1992 to 2009.
In line with ACCIONA’s commitment to sustainable development and the transition to a low CO2 economy, through the operation and maintenance contract a number of actions and procedures will be developed with the aim of optimizing the energy consumption of the installations. To achieve this, ACCIONA and its partner will apply a certified energy management system as per the ISO 50001 standard.
