Grimaud (Var)

Grimaud: a wastewater treatment plant to protect the Gulf of Saint-Tropez

This is a first in the Var department. D’un nouveau genre, intégrant notamment le procédé de traitement des micropolluants CarboPlus®, la station de traitement des eaux usées de Grimaud se veut moderne, fiable et pleinement intégré à son environnement. Stereau has proposed an ambitious project in terms of environmental protection to preserve a fragile ecosystem.

The challenges

  • To comply with the new environmental standards, and even anticipate future legislative and regulatory developments in ecology.
  • To protect an exceptional environment that attracts over a million tourists every year
  • To establish itself as an innovator in the field of water treatment

Our solutions

To combat the threat of micropollutants, Stereau has prioritized the implementation of the CarboPlus® process. This solution has now proven itself in numerous drinking water and wastewater treatment plants throughout France: from endocrine disruptors to organic pollutants, CarboPlus® eliminates no less than 113 micropollutant compounds.

The Grimaud plant has thus become the first wastewater treatment plant on the Mediterranean coast to be equipped with a solution for eliminating micropollutants. A membrane filtration solution for wastewater has also been integrated into the project, to provide optimum filtration of the water before it is discharged into the natural environment. Finally, one of the longer-term objectives of the Grimaud plant renovation is the deployment of treated wastewater reuse, which would aim to directly reuse treated water to water the Saint-Tropez golf course or nearby crops, for example.

In addition to these technical innovations, the project developed by Stereau was aimed at creating a sustainable plant, integrated as naturally as possible into its environment. In addition to these technical innovations, the project developed by Stereau was aimed at creating a sustainable plant, integrated as naturally as possible into its environment. The local ecosystem has not been forgotten, and conservation measures have been taken to protect the most fragile local species.
