Do you know FGWRS?

  • Firmus Grey Water Recycling System is a Monégasque company founded in 2017, specialising in grey water recycling. Its acronym is FGWRS.
  • Our expertise comes from the work of the company FIRMUS France, based in Occitanie, France. This is where our R&D centre is located.
  • We capitalise on its technology and know-how to make it accessible to a wide audience from our strategic position in Monaco.
  • This location allows us to radiate internationally and to actively participate in a hub of continuous innovation.

Since 2017, FGWRS has been developing the commercialisation of “Grey Water Recycling Stations” from Monaco to all territories in demand for the preservation of drinkable water.

The FGWRS technology (Firmus Grey Water Recycling System) comes from the expertise held by FIRMUS France, a company located in Clermont-l’Hérault (Occitanie), France.
