Although 2.1 billion people have, since 1990, gained improved access to better water and sanitation services, the decreasing availability of quality drinking water is an important problem afflicting all continents. It is estimated that at least 1 out of every 4 people will be affected by water scarcity by 2050.
Water scarcity is a problem affecting over 40% of the global population and it is predicted that this percentage could increase due in part to global warming and desertification.
Human beings are the main cause of water pollution. More than 80% of the waste water resulting from human activity is dumped in rivers or the sea without any kind of water treatment, producing contamination.
Water treatment is a process involving different types of operations (physical, chemical, physicochemical and biological), the aim of which is to eliminate and/or reduce contamination or non-desirable characteristics of water.
The objective of this process is to obtain water with the right features for the use intended for it. This is why the water treatment process varies as a function of the properties of the water being supplied and its final use.
Water treatment is increasingly necessary due to drinking water shortages and the growing needs of the global population. Of the planet’s total water reserves, only 2.5% is freshwater - and of this amount only 0.4% is water fit for human consumption.
ACCIONA undertakes the management of end-to-end services which involve all the stages involved in water treatment: readying it for human consumption, supplying it to the population, then cleaning up urban and industrial waste water. The company also takes care of invoicing end users.
