Key data

Metering specialists for almost 50 years


2 sister companies in France

Hydroméca's main site is in Marquion, in northern France. This is where the company produces systems for water metering and custom-built assemblies, and keeps a warehouse of frequently-requested products; the design of industrial gas solutions takes place on the same site.

The branch at Saint-Pierre-de-Mons is home to a strategic logistics site for the south of the country and is the centre for metering operations and equipped assemblies. All the submetering products marketed under the U.D.Access brand are stocked and supplied from this site.  


Combining responsive logistics with custom production

As Hydroméca is focused on customer service and being close to the consumer, it therefore has 2 sites in France, one in the north and one in the south. Both sites have well-organised storage spaces designed to cater for all customer requests, including very urgent orders.

The Marquion site is home to the factories that build the outlet boxes and assemblies for meter wells. This production set-up is specially designed to cater for custom products with the modular designs necessary to adapt to any kind of on-the-ground configuration.
