Faced with global water stress, France is positioning itself as a major player in the reuse of treated wastewater internationally. The expertise developed in water treatment, plant design, and automation enables many French companies to support countries facing critical shortages.
Urgent needs in many countries
In arid or semi-arid areas (the Maghreb, the Middle East, southern Africa, Latin America, etc.), water is becoming a strategic resource. Agriculture and urban uses suffer most from shortages. Reuse of treated wastewater appears to be a sustainable solution for increasing water self-sufficiency while limiting pressure on groundwater resources.
In these contexts, reuse projects focus on:
- agricultural irrigation (olive groves, vegetable crops, arboriculture)
- groundwater recharge
- municipal uses (watering, cleaning, urban cooling)
- industrial food production
Renowned French engineering
French companies in the hydraulic and environmental sector (water treatment, automation, instrumentation) offer solutions tailored to local constraints:
- compact or containerized processing units
- robust systems with low energy consumption
- intelligent automation and remote management
Public-private partnerships enable these infrastructures to be deployed quickly, drawing on international financing models (AFD, World Bank, Green Funds, etc.).
Sustainable water diplomacy
These export projects are not only economic: they also contribute to responsible water diplomacy. By providing concrete solutions to the scarcity of this resource, France is contributing to the stability and development of entire regions, while promoting its environmental expertise.
