Water withdrawals - LRP

Referential built from the sampling works resulting from the declarations of the samplers within the framework of the water charge.

A abstraction work means a set of technical devices for collecting, storing and channelling water from a resource to a primary use.
A abstraction work generally corresponds to an anthropogenic system, that is to say, derived from human activity, developed and maintained by man, with a view to taking water of a significant quantity.
A sampling facility shall be connected to a single water resource, through one or more geographically individualised sampling points, where the latter are known and well identified. A sampling point is a physical connection point between the water resource and a technical water abstraction device relating to the sampling structure in question.
A sampling work MUST be determined in such a way as to best obtain the overall volume taken from the resource.
It MAY be composed of several sampling points where there are so many technical water abstraction devices connected to the same resource at different locations, the water collected at these points being generally mixed upstream or downstream of the meter(s) (water meters), contributing to obtaining the overall volume taken from the resource, at the level of the sampling work. The water collected by each of these points must come from the same resource.

The perimeter relating to a sampling structure MUST be determined independently of the method of distribution of the water collected and carried out downstream of the sampling structure, to receiving environments and different uses (cultural plots for irrigation, lines or drinking water treatment units, industrial process units, receiving water resource, water tower, etc.).

The operation of a sampling structure may be based on one or more methods of physical extraction of water (gravity or diversion, pumping, etc.), with a single method of extraction generally applied at each of its sampling points.

Where there is joint ownership of the material constituting a sampling work, the contracting authority must be the one which has been declared as such to its supervisory instructing body.

The maintenance and operation of a sampling work is the legal and administrative responsibility of a single operator (or manager), who may be identical to the contracting authority, for a period covered by the start and end dates.

A sampling work is located in one and only one main municipality, itself identified by its INSEE code.
In the case of a coastal water abstraction work, it is considered to be located in the municipality having administrative responsibility for the maritime territory or coastal zone in which the abstraction work is located.
