Refurbishment and capacity increase of a campsite’s wastewater treatment system

Refurbishment of a 1300 PE wastewater treatment system



La Farigoulette 5* Campsite




Saint-Laurent du Verdon – France
Our client is a luxury campsite group that owns and operates numerous campsites in France. Located at the edge of a lake in the heart of one of the largest regional natural parks in France, this campsite welcomes more than 1,000 people during the peak summer period. Thanks to several activities offered by the campsite, it is planning to increase its capacity in the future.

The issue faced by our client

This campsite is not connected to the public wastewater system. It operates its own wastewater treatment system which currently consists of a natural lagooning technique. As the size of this treatment system is not sufficient enough to handle an extension to the campsite, our client contacted us to define the increase in capacity of the current wastewater treatment system.
Our client wanted to:

  • Have a cost-effective and scalable solution
  • Reuse the equipment already in place
  • Minimise the volume of sludge to be removed

The project

Working entirely with our client and the French administrative authorities (Direction Departementale des Territoires, DDT 04), we conducted a benchmark study in order to identify the various alternative techniques that could be considered. After having studied these various technical solutions it was unanimously decided to continue the technical study on the implementation of a containerised treatment unit.

1 x 36 m3/h pump

1 clarification container

1 biological reactor container

1 sludge dewatering container

The project comprised several phases:

  • Operational follow-up of current system
  • Design and construction of the additional treatment unit’s water line
  • Design and construction of the additional treatment unit’s sludge line
  • To summarise, Nomado:

  • Performed a benchmark study
  • Completed design studies
  • Drew up a regulatory French Water Law application
  • Supplied 1 x 36 m3/h pump
  • Provided equipment in a compact system
  • Ensured compliance with French regulations
  • Performed on-site commissioning
  • Operated the system
  • Reference standards:

    Order of 21 July 2015 on municipal wastewater collection systems and non-municipal wastewater treatment facilities, excluding non-municipal wastewater treatment facilities receiving a raw load of organic pollution equal or lower than 1.2 kg/day of BOD5. Inter prefectoral Order of 13 October 2014 approving the watershed’s Water Development and Management Plan. Order of 3 December 2015 on the approval of the Rhône-Mediterranean Watershed Master Development and Management Plan adopting the corresponding pluriannual measurement programme.

    The results
    We helped our client in all the project’s phases in order to find a solution to its wastewater management problem.
