The Welsh National Water Development Authority (WNWDA) (Awdurdod Cenedlaethol Datblygu Dwr CymruinWelsh) 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 [1] with its headquarters in Brecon.[2] by virtue of the Water Act 1973[3]
It took over the sewerage and sewage disposal responsibilities of the local authorities within its area, the roles and responsibilities of the six existing River Authorities in Wales and most of the water supply undertakings.[4] The authority was dissolved in 1989 as part of the privatisation of the water industry.
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 three 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, Monmouth, Swansea, Lampeter, Caernarfon and Mold. At the time of this re-organisation the name of the authority changed to Welsh Water Authority.
The authority was governed by a board which included representatives from local authorities, central government and the major industries in Wales including agriculture. The chairman appointed by the government of the day was Lord Brecon but he was replaced by T. M. Haydn Rees in 1976[5] and then by John Elfed Jones in 1982.
In 1989 the water supply, sewerage, and sewage disposal functions of the authority were privatised to form Welsh Water with the regulatory and control functions passing to the newly created National Rivers Authority.
