The city of Nice is experimenting with an innovative solution for storing treated wastewater using a flexible tank from Labaronne-Citaf. This project aims to reduce the consumption of drinking water within the context of sustainable resource management.
Faced with the growing scarcity of water, Nice is adopting a new approach with the REUSE project. In France, less than 1% of treated wastewater is reused, while Spain and Italy have already reached 14%. This pilot project utilizes a 100 m³ flexible tank, installed at the city’s wastewater treatment plant. It allows for the storage of recycled water to irrigate green spaces and clean roadways.
“We chose this solution for its low cost and flexibility,” explains Pierre Geeraert, project manager at Nomado, a partner in the project. This mobile tank meets the temporary needs of the plant under renovation, while ensuring the optimal use of treated water.
A model for other communities
Labaronne-Citaf, the designer of the tank, leverages its 65 years of expertise. More than 4,000 tanks are produced each year, deployed worldwide. In Nice, the tank acts as a buffer reservoir to respond to production peaks. “The demand for treated water is low at night. The tank allows for leveling out the needs throughout the day,” notes Pierre Geeraert.
Since its commissioning in September, the solution has demonstrated its effectiveness. The stored water supplies the tank trucks for water-efficient cleaning of public spaces.
With this project, Nice aims to become a reference point in France for water resource management. The experience could inspire other communities to adopt similar solutions. The city demonstrates that a model based on reuse and innovation is possible, even in urban contexts.
This REUSE project aims to be a concrete response to current climate and water challenges. By promoting the use of treated wastewater, Nice is committed to a responsible and sustainable approach, ready to be replicated elsewhere.
