The project is part of the Danish national wetland scheme, and the aim is to reduce the discharge of nitrogen into the Limfjord. The project is expected to retain about 8.9 tons of N/year, while reducing CO2 emissions by submerging peaty soils – for the benefit of the water quality in the Limfjord.
The wetland project has been completed through different actions:
- Flooding with river water
- Irrigation with drainage water
- Extensification of land
The latter means, among other things, that no fertilizer is allowed on the areas in the future. All actions aim to enhance the natural values of the area, create a more natural hydrology and reduce greenhouse gas emissions.
Envidan has carried out detailed design, tendering, supervision and construction management.
As part of the project, several watercourses have been re-meandered and a number of internal drains and ditches have been removed. As a result, there is now much more flooding with nutrient-rich river water. At the same time, various drains have been disconnected, resulting in irrigation with drainage water from the surrounding fields. The re-meandered watercourses have also created excellent habitats for fish and small animals, and a number of spawning streams have been constructed, e.g. for trouts.
The project was completed in the fall of 2021 and was carried out with support from the European Agricultural Fund for Rural Development.
