Freshwater is a finite resource

Balancing supply and demandComplicated and sensitive urban water cycleClimate change, shortagesWater needs overlap and conflict

Quality, but also quantity: regulations are changingPast issues: quality and wastewater treatmentToday issues: water scarcity Practical, social and economic implications

Environmentally sound water managementComplexity of man’s influence on the water cycleDeterioration of the local ecology

Water recycling benefits your community

Thanks to recycling, used water is transformed into a valuable resource

Recycled water is a drought-proof and growth-enabling solution

Recycling of water leads to a sustainable development of resources

2 million m3/day produced in Veolia Water 100 reuse

installations worldwide, enough water for 14 million people

19 million m3/day produced in all 3,300 water reuse installations worldwide
