How to treat wastewater from a campsite in a natural park?

How to treat wastewater from a campsite in a natural park?

The structure and the environmental context

The client is the owner of a 3-star campsite located in Reyrevignes, France (46), in the Causses du Quercy Natural Park on the border with the Limargue. He wishes to install a sanitation system to treat the wastewater from Domaine Papillon. This campsite consists of 21 pitches for tents, caravans & camper vans, 2 tent lodges, and 14 chalets. 

When the owner acquired this campsite about 1 year ago, he realized that the non-collective sanitation system was no longer in conformity with French law. Indeed, the installed microstation has become obsolete and the cesspool is connected to a non-functional sand filter.

He also has plans to expand the campsite and with it the capacity of the sanitation system. 

The challenge :

The owner of the site has several requirements: 

  • An installation adapted to the very clayey soil,
  • An installation with a capacity of 125 p.e. that would fit into his budget,
  • An installation that does not require electricity to operate. 

The solution :

The MULTIROCK solution was chosen because it is a modular and compact system, which left more than 150m2 free to install a second toilet block. 

In addition, the system operates without electricity and is perfectly suited to prolonged absences and variations in water loads due to seasonal variations. 

Finally, it is suitable for installation in clay soil. The costs of the work were reduced, as concrete reinforcement was not necessary. 

All the owner's requirements were met. 

The results: 

The work went smoothly, and the complete BIOROCK installation (1 primary tank + 5 parallel ECOROCK-5010 treatment units) was completed in only 4 days. 

After verification by a professional, the installation is 100% compliant. The campsite owner is therefore totally satisfied.
