If flooding is a problem, what do you think would be a good solution to prevent it? Why you think that?
To my knowledge it's mainly a problem in the northern parts of Odense. In Stige they often have floods by the harbor, and a good solution might be to build out the sewage system or have pumps for flooding that could drain the areas, and maybe store the flood water for some kind of re-use, considering the quality of it.
Deal with the water locally - fx infiltration of rain water instead of leading it to the sewer system.
I don't know Odense.
First, there are only some areas with flooding problems, but no all. To me, a good solution is an integrated approach that couples both convey system and sustainable solution.
