The purpose of the project was overall to ensure a reduction in the frequency of floods in the area, as well as to reduce pollution of Odense River by reducing the frequency and volume of rain-based reloads from the drainage system
The original drainage plant was old and worn out, as its capacity had been exceeded due to gradual urban growth and increasing rain intensity. The area contained several outdated constructions works, which were supposed to relieve Odense River of wastewater even during small rain events.
The project and its goals have now been met by the building of two large basin plants and by replacing pipes with new ones with a significantly larger capacity. Additionally, some pipes that already had the required capacity were refurbished by excavation-free methods.
In addition, 31 roadside beds have been created, which will handle the future rainwater that falls in the area.
Roadside beds is an example of so-called “green infrastructure”, which distinguishes itself by handling the rainwater close to where it falls, rather than discharging it into pipes. By not directing the rainwater into the drainage system, the amount of water that can cause pollution of the river or flooding of terrain or basements is reduced. In addition, the treatment plant is spared a large amount of water which would otherwise undergo the full purification process. Roadside beds can thus contribute on several fronts to more sustainable rainwater management.
