The Metz Eurometropolis water authoritya public structure in charge of the production and distribution of water in 11 of the 46 municipalities of the metropolis, exploits the sources of Châtel in the Montvaux Valley and the catchment fields of the alluvial aquifer of the Moselle south of Metz , supplemented by those of Rozérieulles and Lorry-Mardigny, which allows it to be for the moment self-sufficientin quality and quantity.
She nevertheless finds herself forced toinvest heavily to adapt to the impacts of climate change.
The Moselle will face recurring episodes of drought tomorrow and extreme precipitation. According to the 2023-2028 Climate Change Adaptation Plan of the Grand Est Region, heat waveswith an average duration of 10 days currently, could reach 32 days per year by 2050.
Summer will lengthen, going from 31 to 52 days, and precipitation, although equivalent in overall volume, will become more irregular and concentrated in certain seasons.
Prepare today for tomorrow’s challenges
Faced with these anticipated upheavals, the Metz Eurometropolis Water Authority must prepare now to guarantee a reliable and sustainable supply to its users. Her multi-year plan 2022-2036in the amount of 41 million euros (excluding taxes), was designed to meet the challenges of today and tomorrow.
It aims to secure the resourcerehabilitate storage tanks, strengthen the distribution network and regularly renew infrastructure, while improving the service provided to subscribers. These operations are often expensive. THE renewal of 8.5 kilometers of the supply pipeline main, backbone of the Régie, is for example costed at 12 million euros (hors taxes).
Of the significant investments have therefore been made since 2018, as explained by Pierre MUEL, Chairman of the Board of Directors of the Water Authority of the Eurometropolis of Metz and Mayor of Marieulles:
“Nearly €15 million has been invested to date for the renovation of the networks in order to limit water losses, in storage structures and for the modernization of the metering system. As a result, it is as much the preservation of the resource, the performance of the installations as the relationship with subscribers that are improved. »

To support local communities in managing water issues, the Bank of the Territories mobilizes at the national level an envelope amounting to 4 billion euros by 2028.
The Water Authority also benefits from a support from the Rhine-Meuse Water Agency via the Territorial Water-Climate Contract. The Agency also finances the initiatives of the Moselle department, which is taking up the issue. THE Water foundations organized in February 2024 were an opportunity to question the future of the territory at the dawn of climate change.
