Environmental data 2012

The environmental performance of Insight Water is managed by the Environmental Management System. This is a set of management procedures used to achieve the global goals set by the Our Environnement Group. This performance is then measured using environmental reporting carried out by the Technical Department .

Baseline figures (such as the volume of water produced and wastewater treatment efficiency etc.) are provided then consolidated according to region.

All business units work using the same modus operandi so that reporting data are homogenous:

  • "Drinking water" activity performance
  • "Wastewater" activity performance
  • "Energy" performance
  • Environmental management
