DATA OF INTEREST

ELNOSA supplies 100% of the chlorine and hypochlorite used in the municipal drinking-water treatment plants (ETAP) throughout Galicia.

Chlorine is the most commonly used water disinfectant in the world due to its effectiveness. The World Health Organization has stated that "Chlorination is the best guarantee of microbiologically safe water" since given the properties of chlorine, is fully effective against all types of microbes contained in the water, the chlorination being the only means to ensure that the treated water remains germ-free during its transit through pipes and tanks before reaching the tap.

Without a local supplier as ELNOSA, such ETAPs should be supplied by other suppliers located outside Galicia: Catalonia, Basque Country, Andalusia and Portugal.
