The client challenge
The Ciela Village group operates the 5-star campsite «La Farigoulette» in Saint-Laurent-du-Verdon (04500), a 265-pitch site set in the exceptional natural surroundings of Lac de Sainte-Croix.
Faced with growing visitor numbers and increasingly strict regulatory requirements for discharges into the natural environment, the campsite undertook a project to upgrade and increase the capacity of its wastewater treatment plant, from 600 to 1,300 population equivalents (PE).
Ciela Village needed a solution capable of:
- Treating wastewater from an upgraded 5-star campsite, with high discharge quality requirements
- Integrating into a classified natural site with a reduced footprint and limited visual impact
- Being deployed rapidly and operational before the tourist season
- Complying with the regulatory framework (Water Act file)
To meet these challenges, Ciela Village brought Nomado in from the very start of the project, entrusting it with both the studies and the construction.
The Nomado solution
Nomado managed the entire project from design through to commissioning, with a turnkey approach combining engineering, regulatory procedures and modular manufacturing.
Our intervention was structured around three axes: regulatory rigour, treatment performance and compact deployment.
An MBBR process in maritime containers
The unit deployed by Nomado treats wastewater at a flow rate of 36 m³/h using a biological MBBR (Moving Bed Biofilm Reactor) process, recognised for its high performance within a compact footprint:
Pre-treatment
- Lift station (36 m³/h): intake and flow regulation
- 20ft pre-treatment container
Biological treatment
- 20ft MBBR reactor container: mobile biofilm carrier bed ensuring degradation of carbonaceous and nitrogenous pollution with an optimised contact surface
Secondary treatment
- 20ft secondary treatment container: clarification of biologically treated effluents before discharge into the natural environment
Comprehensive support, from project to field
Engineering and regulatory
- Design study and sizing (water and sludge stream)
- Drafting of the Water Act file (DLE) and management of administrative procedures with the authorities
Deployment and operation
- On-site commissioning by Nomado teams
- Operational assistance for ramp-up and team training
Results achieved
- Treatment capacity increased to 1,300 PE, in line with project objectives
- Fully containerised plant, discreetly integrated into the campsite's natural environment
- Commissioning completed on schedule with no impact on site operations
- Regulatory compliance ensured from start-up
