A regional water authority, commonly known as a water board, was one of a group of public bodies that came into existence in England and Wales in April 1974, as a result of the Water Act 1973 coming into force. [1] This brought together in ten regional units a diverse range of bodies involved in water treatment and supply, sewage disposal, land drainage, river pollution and fisheries. They lasted until 1989, when the water industry was privatised and the water supply and sewerage and sewage disposal parts became companies and the regulatory arm formed the National Rivers Authority. Regional water authorities were also part of the Scottish water industry when three bodies covering the North, West and East of Scotland were created in 1996, to take over responsibilities for water supply and sewage treatment from the regional councils, but they only lasted until 2002, when they were replaced by the publicly owned Scottish Water.
