The staff of almost 900 works to achieve the major missions of Onema in continental France as well as in the overseas territories. Using their skills and know-how gained in the field, engineers and technicians work on aquatic environments throughout the country, in the national headquarters, in the nine regional offices and the local offices.

  • Regional offices


    Nine regional offices group engineers and technicians who are specialised in gathering and processing data, in providing technical support for water-management policies and efforts, and in organising surveillance activities for aquatic environments.

  • Local offices


    The technicians and environmental technical agents working in local offices have two main missions: inspections on water use and policing activities on water and fishing; collection of data on the status of environments and species.
