Two new achievements for the start-up of Nice to control floods in urban areas

F-REG, a startup set up at the CEEI in Nice and created in 2014, proposes an innovation that tackles the control of floods in urban areas and the reduction of rain pollution as a result of overflowing sewerage networks. It has just finalized two new projects in Biot and Marseille.

The startup F-Reg (for Flux-Régulation), led by its co-founders Thierry Courbon and Emmanuel Curinier, has just completed two projects with the city of Biot on the one hand and Euroméditerranée in Marseille on the other.


In Biot, it is the project of the parking of the Bowsets where four hydrodynamic valves were installed to increase the storage capacity of the retention basin of the city (from 450 to 602 m3 ). Thanks to the over-sizing of 267 ml of pipes, the installation of these four hydrodynamic valves of different diameters, this new storage volume would have absorbed 83% of the rain fell on October 3, 2015.

In Marseille, for Euroméditerranée, F-Reg has set up a rainwater storage system under the roadway avoiding the construction of a retention basin that would have mobilized more than 5,000 m² of land.


 F-Reg, the winner of the Water Ressourcer Challenge competition run by Véolia in 2018, employs seven people and plans a turnover of €400,000 in 2019.

The ambition of Emmanuel Curinier, General Manager: “Reduce the impact of our society on the environment, and in particular on the quality of surface water. For this, we have developed a new tool: a hydrodynamic valve for autonomous regulation.”

The innovation of the startup is aimed at the local authority market, with this unique concept that allows a new approach to the management of sanitation networks in urban areas that saturate and overflow during the rains. At stake, the control of floods and the reduction of rain pollution.
