Any person required to connect to the sewerage system and who obtains all or part of their water supply from a source that is not part of a public service must declare this to the town hall.
In the event that the use of this water generates the discharge of wastewater collected by the sanitation service, the collective sanitation fee is calculated:
– either by direct measurement using metering devices installed and maintained at the user’s expense and whose readings are transmitted to the sanitation service under the conditions set by the authority mentioned in the first paragraph of article R. 2224-19-1;
– or, in the absence of metering devices, justification of the compliance of metering devices with regulations or transmission of readings, on the basis of criteria for assessing the volume of water withdrawn, defined by the same authority and taking into account in particular the surface area of the dwelling and land, the number of inhabitants, the length of stay.
