Intense rain storms caused by climate changes are resulting in great challenges for the Danish sewer system. If Blue Flags and bathing water quality is to be maintained, then the emission of rain-mixed waste water must be decreased. One way this can happen is by sinking concrete basins into the ground and that is just what the Municipality of Århus is doing in the centre of Århus.
Every prognosis points to the same conclusion, shows a 'State of the Nation' report from the Consulting Engineers Association. The rainstorms of the future will be greater and more violent. This means that the sewer capacity needs to be increased and here sustainable concrete is an obvious choice. At this moment, the Municipality of Århus is constructing large concrete basins, which can gather up rain and sewer water, so the city's sewers do not overflow into Århus Å among other things.
“It is a big problem that the sewer systems in Denmark are not at all geared to take on these amounts of water. It is necessary to think in long-term solutions, if we are going to maintain a high bathing water quality and avoid flooding. Many cities and areas are facing the same problems with a lack of capacity. An obvious and economic choice is concrete basins that gather up the rain water until there is room in the sewage treatment plant. Completely in line with the environmental profile that the municipalities want. The concrete is sustainable, durable and easy to form explains” Ole Nørklit, chairman of Danish Concrete.
