World Water Day: what are the challenges surrounding wastewater?
Established by the United Nations General Assembly, World Water Day has been marked since 1993. Organised on 22 March each year, this event highlights a specific theme relating to water resources.
In 2017, the day's focus is on wastewater.
Wastewater is a resource...
Across the entire world, wastewater management is severely neglected, despite the growing quantity of wastewater. Of the 165 billion m³ of wastewater collected and treated every year, only 2% is reused.
However, the potential of this wastewater is significantly underestimated. It can be used as:
- a sustainable source of water;
- a source of energy.
SUEZ promotes the idea that wastewater is a resource with significant potential.

...that should be used to the full !
Once treated at water treatment plants, wastewater can be discharged into the environment or re-used (watering, irrigation or industrial processes). By reducing the volume of sludge produced in this water, it can also be re-used in the form of energy (biogas) or in agriculture.
By re-using wastewater, SUEZ provides practical solutions in order to:
- create resource cities;
- provide solutions for industry stakeholders;
- develop sustainable agriculture.

Wastewater treatment: a social responsibility
2.5 billion people still do not have access to safe sanitation facilities. Every year, 280,000 people die due to problems with unsuitable facilities.
This is why the Fonds SUEZ Initiatives supports NGOs and charitable organisations that work to improve access to sanitation for vulnerable populations in developing countries.
