Welsh National Water Development Authority

The Welsh National Water Development Authority (WNWDA) (Awdurdod Cenedlaethol Datblygu Dwr Cymru in Welsh) and later the Welsh Water Authority was one of ten regional water authorities set up in the UK and came into existence on 6 August 1973 with its headquarters in Brecon. by virtue of the Water Act 1973

It brought together all the sewage disposal, sewerage and water supply functions previously held by local authorities in Wales. It also subsumed all the functions of the six River Authorities in Wales - the Wye River Authority, the Usk River Authority, the Glamorgan River Authority, the South West Wales River Authority, the Gwynedd River Authority and the Dee and Clwyd River Authority. The boundary of WNWDA was identical to that of the constituent River Authorities and included parts of England in both the River Wye and River Dee catchments. Private water companies such as Chester Water were excluded and continued in operation.

At inception, WNWDA was organised in units that broadly reflected the originating business. Thus sewerage and sewage disposal was organised into a number of Sewage Divisions, water supply was similarly formed into a number of Water Divisions and River Divisions exactly matching the roles and boundaries of the previous River Authorities were created.

In 1984 a major re-structuring brought all the functions together in 3 multidisciplinary Divisions, with a headquarters in Brecon. These were the South Eastern Division based in Nelson, South Western Division based in Haverfordwest, the Northern Division based in Bangor. There were sub-offices located in Hereford, Swansea and Caernarfon respectively. At the time of this re-organisation the name of the authority changed to Welsh Water Authority.
