There are two ways to carry out the infiltration of rainwater: the first consists of doing it through the ground using permeable pavements, and the second is to collect rainwater through drains, which lead the water to the infiltration tank.
Although the most natural is to do it through the terrain, there are times when it is not possible, and you have to resort to conventional capture. Either because the work is existing and it is possible for us to change the entire pavement, or because there is contamination that must be removed from the rainwater before infiltration.
The removal of floating, suspended solids, hydrocarbons or metals can be carried out in the same sumps or through hydrodynamic separators.
