Turning on a tap. An ordinary, everyday gesture. And yet, before it comes gushing from the tap, the water has been on a long journey. Tap water is not naturally drinkable, unlike commercially available mineral and spring water. It only becomes drinkable thanks to extensive physical and chemical treatments. The production of drinking water is a crucial issue for populations. SUEZ offers operators effective solutions to produce quality drinking water in sufficient quantities to meet the needs of both individuals and professionals.

Your challenges

Produce quality drinking water in sufficient quantities

Water is declared drinkable and can be distributed to consumers only when it meets well-defined quality parameters. It is, moreover, one of the most stringently controlled food products. It is subject to extreme vigilance at every stage of its journey, from collection to distribution. 


The production of drinking water thus requires expertise in multiple technologies and processes as well as the ability to anticipate requirements, which involves precise knowledge of water resources. Available reserves of natural water include groundwater (water tables), standing or running surface water (lakes, rivers, etc.), and seawater. The implementation of a treatment system to produce water that is suitable for drinking depends on the quantity of water available, its quality (taking into account the possible variations), economic costs and environmental constraints.
