Protect aquatic environments by inspecting use and enforcing regulations

An advisory role in support of the administrative police

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.

Enforcement activity

For surface waters, rivers and wetlands, agency personnel carry out inspections in the field to enforce regulations on usage of water and aquatic environments. Onema focuses on the most sensitive environments and on the priority issues targeted by the Water framework directive. Under the authority of State prosecutors, it signals any offences and assists the prosecutors in bringing cases to court. 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.
