World Water Day: reuse of treated wastewater in France


💧Today is World Water Day. Water, that essential resource for our lives that we use to excess, but still reuse too little. ♻️ 

World Water Day is a day to raise awareness of a sustainable management of water resources. Established by the United Nations in 1992, it is celebrated on March 22. Each year, World Water Day highlights a specific aspect of freshwater.

In France, less than 1% of treated wastewater is reused, far behind Italy and Spain, which reuse between 8% and 14%, and far behind Singapore (40%) or Israel (90%).

So we're way behind schedule. And yet, with the number of droughts on the increase and the water table deteriorating, we are still lagging far behind, reuse of treated wastewater (REUT) should no longer be an option.

Grey and black water treatment remains restrictive, restrictive and, above all, up to the individual. To date, there is no obligation to do so, and average processing times do not allow us to respond effectively to the urgency of the situation (for example, it takes an average of 1 year to process a request for authorization to reuse treated water for watering green spaces).

This week, Elisabeth Borne is due to announce the government water plan*, i.e. some fifty new measures to achieve 10% water savings by 2030, rising to 30% by 2050.

We're looking forward to the announcement!

*PS: After the publication of this article, the Government published its action plan for resilient, concerted water management.
