Sampling works - Martinique

Reference framework built from the sampling works resulting from the declarations of the collectors in the framework of the water levy. A sampling structure is a set of technical devices for the abstraction, storage and channelling of water from a resource for primary use. A abstraction work generally corresponds to an anthropogenic system, that is to say, resulting from human activity, developed and maintained by humans, with a view to obtaining water withdrawals of significant quantities. A sampling structure 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 materialises a physical connection point between the water resource and a technical water abstraction device related to the sampling structure in question. A sampling structure 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 as many technical water abstraction devices connected to the same resource at different locations, the water captured at these points being generally mixed upstream or downstream of the metering device(s) (water meters), contributing to obtaining the overall volume taken from the resource, this at the scale of the sampling structure. The water captured by each of these points must come from the same resource. The perimeter of a sampling structure MUST be determined independently of the mode of distribution of the water taken and carried out downstream of the sampling structure, to different receiving environments and uses (cultivation plots for irrigation, drinking water queues or 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.), a single method of extraction being generally applied at each of its sampling points. Where there is co-ownership of the material constituting a sampling work, the developer must be the one who has been declared as such to his supervisory investigating body. The maintenance and operation of a sampling facility is under the legal and administrative responsibility of a single operator (or manager), who may be identical to the contracting authority, during a period covered by the starting and finishing dates. A sampling structure is located in one and only one main municipality, itself identified by its INSEE code. In the case of a coastal water abstraction structure, it is considered to be located in the municipality having administrative responsibility for the maritime territory or the coastal area in which the abstraction structure is located.
