Rainwater management

VMZINC solutions participate in the management of rainwater in buildings and are compatible with installation of rainwater harvesting systems.

Whether they are used:

  • for roofing or facade to ensure the building is watertight,
  • in rainwater evacuation systems to collect, evacuate and direct rainwater,
  • or as an element in screw-on downpipe systems for easy effective connection of rainwater harvesters,

In France, harvesting and re-use of rainwater for exterior use (watering gardens, washing cars) is authorized and even encouraged (eligible for a tax credit) without any discrimination in terms of the type of materials used for the building envelope. For interior sanitary use (e.g. toilets and washing machines), re-use of rainwater is authorized without discrimination in terms of type of materials but must comply with the recommendations of the sanitary authorities (10).
