CMA Grand Est1
How can water management equipment be funded in a construction business?
Construction craftspeople: discover the CMA Grand Est and Agence de l'eau Seine-Normandie grant to reduce water consumption and fund equipment.
Text
For construction craftspeople, water consumption, discharges and the storage of hazardous products can represent economic and environmental challenges. The CMA Grand Est is relaying a scheme from the Agence de l'eau Seine-Normandie combining a personalised assessment, advice and financial support for certain investments. Funding depends on the territory, the project and the review of the application: the work must not begin before the application is submitted on the designated platform.
Text
The CMA's announcement targets construction craftspeople located in the Seine-Normandie basin, particularly in the Aube and Marne départements, as well as certain areas of the Ardennes, Haute-Marne and Meuse. Membership of the river basin and the exact scope must be confirmed with the CMA's environmental advisor.

Do not confuse the river basin's coverage with the entire Grand Est region: the source cites specific départements and areas. The rate varies by location. The minimum amount of €3,500 including tax relates to the funded project, and not necessarily to the amount of the grant. Obtain the rules and confirmation of the application process before placing any order.
