Future of the Gillbach: How the coal phase -out is changing water guidance

Future of the Gillbach: How the coal phase -out is changing water guidance

The changes that the coal phase-out at the Hambach opencast mine and in the Niederaußem power plant not only affect the immediate area, but also the Gillbach, an important watercourse in the region. The Gillbach, whose natural source was once found in the Bethlehemer forest, has changed a lot by lowering the groundwater for years.

challenge for the communities

A responsible engineer of the Erftverband explains that the Gillbach is currently almost exclusively dependent on the derived cooling water of the power plant. With the closure of the power plant, the stream threatens to return to its original state, which means that it could often dry up in dry times. The Gillbach is an important identity -creating element for the residents and the surrounding communities of Rheidt and Hüchelhoven. Mayor Martin Mertens (SPD) emphasizes how important this watercourse is for the quality of life of the region.

Refurbishment projects in Rheidt and Hüchelhoven

Renaturation projects in the region have shown how valuable the Gillbach can be for local recreation and for ecological purposes. In Rommerskirchen there are now areas that are used by walkers and cyclists. Picnic spaces and hiking trails ensure that nature remains accessible to the citizens. "We also think of the creation of green classrooms and information boards," says engineer Dietmar Jansen. In addition, it was easier to make future new development areas environmentally friendly.

Future water treatment

A future-oriented concept stipulates that rainwater is not quickly derived, but is kept in the region to supply the Gillbach. This can be done by special retention basins and underground water reservoirs. "The goal is to be able to regulate the water levels in order to keep the stream alive even in dry times," explains Jansen.

Pilot project for water supply

A working group has already started to create a concept for the descriptive development of the Gillbach run. This is particularly important, since from 2030 the Rhine will be additional water reserves supplyen to support the Gillbach in its ecological balance. This would be a valuable measure against the negative effects of the coal exit and could possibly serve as a model for other regions.

ecological and social protection

Mayor Mertens is confident: "The project will not only be important for flood protection, but also strengthen social cohesion by upgrading nature." In view of the need to reconcile urban development and nature conservation, the participation of the district government is also rated as positive.

Future view

The solution to the challenges that coal phase-out entails could give the Gillbach a new life, and also upgrade the region. The Gillbach could develop into an ecological backbone that benefits both the surroundings and the wildlife and at the same time offers people a place of relaxation.
