Water retention in Herningsholm River
Greater water flow capacity, lower water level and reduced risk of flooding during heavy rainfall. These were some of the requests put forward by the Municipality of Herning and Herning Vand when they asked us to help them adapt the river to cope with climate change. Sweco investigates potential sites to determine their suitability for water retention – a climate solution that also offers recreational opportunities and increased biodiversity.
The aim of the project is to ensure greater water flow capacity and reduce the risk of flooding during heavy rainfall. The delay is to be achieved by retaining water in suitable areas of the river valley, with a focus on improving recreational opportunities and the natural environment.

Investigation of suitable water retention sites in the river valley
The project includes the preparation of a conceptual proposal/consultation paper, data collection, mapping, field studies, impact assessments, public consultations and preparation of a comprehensive environmental impact assessment in cooperation with the developer and the Danish Nature Agency Roskilde.
Initial investigations of the area gave the Municipality of Herning and Herning Vand insight into the possibilities available to help them choose the solution that best meets their climate change adaptation needs.
Climate change adaptation creates recreational value and improves the natural environment
The aim of the climate change adaptation of Herningsholm River is to ensure greater water flow capacity and control the water during heavy rainfall, while also lowering the water level of Herningsholm River at the Herning central wastewater treatment plant.
The delay is to be achieved by retaining the water in suitable areas of the river valley, with a focus on improving recreational opportunities and increasing biodiversity.
