Each year, Natural Resources Wales spends around £6m on maintaining our defences and main river watercourses.
Our maintenance activities are carried out in line with Welsh Government policy.
We focus our efforts on activities that help us manage flood risk and on cases and situations where economic and environmental considerations justify intervention. The routine activities we undertake include:
- maintaining flood barriers and pumping stations
- clearing grills and removing obstructions from rivers
- controlling aquatic weed in rivers
- removing silt and gravel from river beds
- managing grass, trees and bushes on our flood embankments
- inspecting and repairing flood defence structures
