A resident can submit a request to the Service des infrastructures, division des travaux publics. However, specific weather conditions are essential for a successful operation. The humidity level is especially important. Dry conditions prevent the dust suppressant from adhering to the ground, while too much water accumulation on the ground (following heavy precipitations) encourages the formation of holes.

The public works department therefore waits for the best weather condition to proceed once a request has been submitted by a resident.

It can be done twice per year, once in the spring and once, if necessary, around the end of August.
