The use of water unfit for human consumption is possible for certain domestic uses or in the food businesses mentioned in the first paragraph of I of article L. 1321-1, when the quality of this water has no influence, direct or indirect, on the health of the user or on the wholesomeness of the final foodstuff.
A decree in the Conseil d’Etat determines the procedures for applying the provisions of this chapter and in particular, for each type of water concerned:
1° The possible categories of use and the conditions to which each is subject;
2° The cases in which the use of water is subject to an authorisation issued to the user or producer by the competent State authority or to a prior declaration made by the user or producer to that authority;
3° The terms and conditions under which the user or producer is required to implement monitoring measures and submit to control measures, as well as the conditions under which the costs associated with the control may be charged to them.
