Consultation Nationale - du 15 avril au 15 octobre 2008
It is possible to guarantee our safety while also preserving “free” spaces for river water. This enables dispersal of the excess energy from high water levels, recharging of groundwater bodies, guaranteeing the safety of goods and people, and preserving good water condition.
Creating natural “buffer” zones against rising water levels is preferable to building structures (Dams, barriers). Certain structures can have harmful effects. They increase the strength of rising water downstream, resulting in catastrophes.
The impermeability of ground surfaces in towns (car parks, squares, etc.) leads to pollution when it rains and the transfer of polluted water. So-called “alternative” techniques exist. These allow infiltration of rainwater into the ground, which filters it and regenerates water resources without polluting them. Vegetation in towns (without pesticides) also has a highly beneficial effect on water and air quality and limits the greenhouse effect.
Reintroducing vegetation to the banks of watercourses is essential in order to protect river water quality and fauna.
