I assume the hon. Member’s question refers to catchments areas under the Water Framework Directive, rather than the waste framework directive.
The Water Framework Directive requires us to introduce a new water quality planning system, using geographical units called river basin districts, which are made up of whole numbers of catchments or “river basins”.
Article 3 of the Water Framework Directive requires that individual river basins be identified and assigned to river basin districts. We carried this out in our transposition regulations. The catchments in England and Wales have been grouped to form six river basin districts and an additional four cross border districts, including two with Scotland and two with Wales.
