Designing, building, operating and maintaining a treatment plant

We have the technology and expertise to design, build, operate and maintain treatment facilities that produce drinking water, treat wastewater and recycle and recover solid waste.

You will be sure that the treatment facility will operate in line with the design in terms of:
- Complying with the required performance standards
- Delivering the full capacity determined at the design stage
- Limiting operating and maintenance costs
- Ensuring its longevity through proper maintenance
You can safely adopt the latest innovations
- Our performance guarantee allows you to use the most innovative, advanced technologies in a risk-free way
- The associated operational and maintenance period allows you to develop the local workforce required to operate and manage the new facility, with a gradual transfer of knowledge
You benefit from our experience in operating and maintaining existing similar infrastructure

Building, financing, operating and maintaining a treatment plant

We can also help you via a Public-Private Partnership (PPP) contract. This type of contract allows you to obtain full or partial funding for the construction of a new facility or improvement works on an existing facility. We can offer funding solutions covering up to 100% of the amount required.

A Biofactory® in Villiers-Saint-Frédéric (France): a showcase for innovation relating to the circular economy

SIARNC – an organisation that handles wastewater treatment in the Yvelines region of France – tasked us with modernising its plant and increasing its capacity, with the aim of converting it into a Biofactory®. This wastewater treatment plant now generates new resources while protecting the environment. We put in place technologies at the site to convert sludge produced by the plant as well as external sludge into energy and produce a new source of phosphorus.
