Water and the law

Water is no ordinary consumer commodity: it is a vital resource that requires protection, and that must be safeguarded and treated as such. This is the principle that underlies the framework directive on water (European Parliament and Council directive 2000/60/CE of October 23 defining a framework for a community policy on water).

The Neptune filtering system fulfils two environmental objectives:
  • To save drinking water: 700,000m3 per year, i.e. the equivalent of the annual consumption of 5,000 families of four in France.
  • To reduce emissions of insoluble fine matter in suspension into the waste water circuit, by 450 - 525 tonnes per year.
