    Activities of Water



    The drinking-water treatment or purification process consists of a series of actions to treat the water in order to make it suitable for human consumption. The process is carried out in a Water Purification Plant.

    ACCIONA Agua offers a range of innovative solutions designed to overcome the problems involved indrinking-water treatment. It has built 115 plants in all, with a total capacity of more than 7million m3/d enough to satisfy the water needs of nearly 26 million people.



    The wastewater treatment or purification consists of a series of processes that remove or reduce the physical, chemical and biological contaminants from water coming from public use to achieve the quality and quantity required characteristics. The process is carried out in a Wastewater Treatment Plant(WWTP).

    ACCIONA Agua delivers efficient wastewater treatment solutions at minimum installation costs. The company runs more than 300 plants with a total capacity of 13,2 million m3/d that meet the needs of apopulation of nearly 54 million inhabitants.



    Desalination consists of a series of processes to remove part or all salt and other minerals from seawater or brackish water to transform it into suitable for irrigation or drinking purposes. The desalination process is carried out in a water desalination plant, also known asSeawater Reverse Osmosis (SWRO).

    ACCIONA Agua is a leader in Reverse Osmosis sea- and brackish-water desalination. Its broad experience covers the entire project life-cycle: design, build, commission, and O&M.

    More than 70 desalination plants, producing a total of over 2.3 million m3/d, supplying more than 10.5 million people



    ACCIONA Agua runs WWTPs and DWTPs with its sights set on optimizing all aspects of the treatment by applying cutting-edge technology, minimizing energy costs, carrying out ongoing tests to monitor water quality, and efficiently managing the sludge, waste and byproducts generated by the treatment processes.

    ACCIONA Agua applies a policy of sustainability in the operation and maintenance of its facilities, for example by minimising the emissions of odours and noise, reducing energy consumption and reusing effluent water in the preparation processes for reagents.
