Onema provides State services with technical opinions on requests for use and authorisations in the framework of water-policing activities. These opinions deal generally with the status of the environment, the potential impact of projects and the value of the proposed corrective or compensatory measures. Onema also assists the water police in identifying rivers, wetlands and spawning zones, and in recreating ecological continuity in rivers.
For surface waters, rivers and wetlands, agency personnel carry out inspections in the field to enforce regulations on usage of water and aquatic environments.

In the event of negotiations between the administrative authorities and the offender, Onema assists the administration in evaluating any damage caused to the environment and the necessary corrective measures.
