The development of cities and their suburbs has made the stormwater networks insufficient, causing more and more frequent and important floods.
In the same way, the deterioration of the receiving environments (where the water is discharged); the fact that stormwater is often polluted forces the developers and the communities to turn to
To minimize these impacts, stormwater management requires the implementation of techniques called “compensatory” or “alternative” aiming at:
– Either to reduce the impervious surfaces.
– Or to infiltrate the water on the plot (as close as possible, to reduce the volumes flowing downstream).
– Or to store them and then return them to the public sewerage system in a deferred manner.
