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 objective was to improve the quality of the treated water and of the sludge and gases generated during the process, as well as to optimize the efficiency of the facilities by implementing technologies that allow treatment at the lowest cost.
A storm pool was installed to collect water from heavy rainfall to prevent it from overflowing into the stream and to improve environmental protection. In addition, an area was created to optimize the biological process of water purification, improving the elimination of nitrogen and phosphorus. The sludge extraction system will also be optimized.
This treatment plant belongs to the four treatment plants of the municipality of Calvià, in Mallorca, Balearic Islands. The Santa Ponça treatment plant, the largest in the municipality, treats 71% of the total wastewater generated; Peguera 15%, Bendinat 11% and Calvià 3%.
