Help our clients to better manage the water cycle as a whole


In addition to applying the regulations in force in relation to the quality of drinking water, treatment of waste water and the prevention of pollution in natural environments, we are committed to running voluntary research programmes on emerging pollutants (for example new micropollutants such as residue from pharmaceutical substances), sharing the results of this research with the authorities and the legislator, and proposing appropriate prevention plans.


We promote the development of alternative water resources by encouraging our clients to implement this where possible and applicable (reuse of waste water after treatment by purifi cation plants, recovery of rainwater, desalination, etc.).

We contribute to noticeably limiting losses in drinking water networks by deploying tools which enable better knowledge of assets (plants, pumps, pipelines…) and by developing advanced leak detection technology (acoustic detection sensors for example).

We encourage the management of water consumption through awareness-raising campaigns, the circulation of client information, the installation of smart meters and the development of new consumption operating tools (especially smart meter), as well as by proposing the implementation of tailored price setting to local authorities.

We help our clients to adapt to the effects of climate change, especially through our expertise in hydraulic and climatic model design, and our engineering advice on creating urban developments which are more resilient to the effects of extreme weather conditions.

Quantitative objectives

  • Reduce losses from drinking water networks to avoid wasting a volume of water equivalent to the annual consumption of a town with 2 million inhabitants.
  • Aim to equip over 20% of our clients with smart meters.

Progress objectives

  • Increase the reuse of treated waste water.
