The implementation of the Water Framework Directive (WFD) has been an intensive on-going process since the Directive’s adoption in 2000. The aim of the WFD is the achievement of "good status" of surface water and groundwater by 2015. To reach the environmental objectives of the WFD, river basin management plans and programmes of measures must be formulated and implemented in all river basin districts (RBDs) of the EU, including international RBDs.
