54.This section would apply the new water supply and sewerage licensing arrangements to the areas of undertakers wholly or mainly in Wales as they apply to undertaker areas wholly or mainly in England. The Welsh Ministers have the power to bring Schedule 5 into force. Under paragraph 2 of Schedule 12 the Welsh Ministers can only exercise their power through an order under the affirmative procedure before the National Assembly for Wales. The amendments in Schedule 5 amend or repeal words of the WIA, as amended by other provisions in this Act, that prevent the new water supply authorisations and the new sewerage licences from applying to undertaker areas wholly or mainly in Wales.
