The Pays de l'Or Agglomération was looking for technical support and methodological support to concretely set up channels for the Reuse of Treated Wastewater in its territory.
For more than 15 years, different considerations have already been initiated in certain municipalities, notably at the level of La Grande Motte and Mauguio, to recover the treated wastewater from treatment plants.
The Pays de l'Or Agglomération wanted to respond to the Rhône-Méditerranée-Corse Water Agency's call for projects by presenting a REUSE project for the La Grande Motte wastewater treatment plant. In order to maximize the success of this project, Le Pays de l'Or Agglomération entrusted Ecofilae with carrying out a study to assist the contracting authority.
The study carried out by Ecofilae aimed to update the previous studies carried out by the Pays de l'Or Agglomération with regard to the uses identified and regulated in the decree of August 2, 2010 (revised on June 25, 2014 and then on April 26 2016). Unregulated uses such as street washing, vehicle washing and port uses will be taken into account in the proposed wastewater reuse scenarios.
Beyond the regulatory aspects, this study also takes into account the evolution of water needs for the different uses identified previously in the studies.
After validation of the scenarios by the project actors, Ecofilae proposed a global pre-costing for the implementation of the project.
Finally, Ecofilae assisted the Pays de l'Or Agglomération in drafting the grant request to respond to the call for projects from the Rhône-Mediterranean-Corsica Water Agency.
