Regional water authority
Regional water authorities came into existence in England and Wales in April 1974, as a result of the passing of the Water Act 1973. 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.
The idea of organising water management into regions based on river catchments had been around for nearly 100 years, since the Duke of Richmond had introduced an Act of Parliament in 1878 promoting the idea. The council of the Society of Arts had offered to award medals for plans to divide England and Wales into watershed districts, to assist in the conservancy of natural resources. The silver medal was awarded to Frederick Toplis in 1879, whose twelve watershed districts cover remarkably similar areas to those established under the 1973 Act. However, the idea was not pursued at the time, but from the 1930s, the idea took shape.
First came catchment boards, created by the Land Drainage Act 1930. While they were primarily concerned with land drainage and the prevention of flooding, they paved the way for river boards, which were established in 1948, and covered the whole of England and Wales. As well as land drainage, they were responsible for fisheries, the prevention of pollution and the gauging of rivers. River boards were replaced by twenty-seven river authorities as a result of the Water Resources Act 1963, and they gained further responsibilities, covering the monitoring of water quality and the protection of water resources. They thus became responsible for inland waters and the underground strata which existed within their area. Sewerage boards had been largely responsible for sewage collection and disposal in areas defined by local authority boundaries and water supply had been managed by quasi regional water boards.
With the establishment of the water authorities in April 1974, England and Wales had, for the first time, organisations which were responsible for all aspects of the management of water within a geographical region, defined by a river basin or a series of river basins. As well as the management of water resources, which they inherited from the river authorities, they were also responsible for water supply and the disposal of effluent. Most uses of water are interconnected, since the removal of water from a river for spray irrigation reduces the amount of water available for drinking water supply, and the pollution of a river by sewage prevents such a use. Most drinking water supplies had been managed by local authorities, but the Central Advisory Water Committee, which reported in 1971, had found that this system was inflexible, and the new water authorities took over 157 water supply undertakings from local authorities and joint water boards. Some thirty independent water supply companies remained, but operated under agency agreements with the new bodies.
The treatment and disposal of sewage was also removed from the local authorities and given to the regional water authorities. The Working Party on Sewage Disposal, which reported in 1970, had suggested that there were over 3000 treatment plants which were producing sub-standard effluent discharges. Over many years there had been little incentive to improve the quality of treatment, but the water authorities were given the task. Some 1,400 sewage authorities were divided among the ten water authorities, as it was recognised that the discharge of treated effluent was a major element in the total hydrologic system.
The ten new authorities were:
- Anglian Water Authority - The areas of the East Suffolk and Norfolk, Essex, Great Ouse, Lincolnshire and Welland and Nene River Authorities, except the part of the area of the Essex River Authority which is included in the area of the Thames Water Authority
- North West Water Authority - The areas of the Cumberland, Lancashire and Mersey and Weaver River Authorities
- Northumbrian Water Authority - The area of the Northumbrian River Authority
- Severn Trent Water Authority - The areas of the Severn and Trent River Authorities, except the part of the area of the Severn River Authority which was included in the area of the Wessex Water Authority.
- South West Water Authority - The areas of the Cornwall and Devon River Authorities and part of the area of the Avon and Dorset River Authority .
- Southern Water Authority - The Isle of Wight and the areas of the Hampshire, Kent and Sussex River Authorities, except the part of the area of the Kent River Authority which was included in the area of the Thames Water Authority.
- Thames Water Authority - The Thames Catchment Area, the Lee Catchment Area and parts of the area of the Essex River Authority and of the Kent River Authority that drained to the Thames estuary
- Welsh National Water Development Authority (WNWDA) including all the catchments of 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 . Parts of the WNWDA area including parts of the River Dee and the River Wye extended into England
- Wessex Water Authority - Most of the area of the Avon and Dorset, Bristol Avon and Somerset River Authorities and part of the area of the Severn River Authority draining to the lower Severn estuary
- Yorkshire Water Authority - The area of the Yorkshire River Authority
Governance of the regional water authorities was by boards of governors. The size of the board differed from authority to authority, with the smallest being 14 governors plus a chairman for Wessex Water and South West Water, and the largest being Thames Water, with over 50 members. Over half of the members were nominated by local authorities, with the remainder being appointed by the Minister of Agriculture, Fisheries and Food, the Secretary of State for the Environment, or the Secretary of State for Wales. Such appointments were normally based on technical expertise, to complement the more local interests of local authority appointments.
Although all aspects of water management were under one body for each region, the new authorities still had to deal with two government departments when major capital expenditure was involved. For flood protection and land drainage schemes, the powers of the Land Drainage Act 1930 and the Land Drainage Act 1961 were largely unaltered, and the approval of the Ministry of Agriculture was required. For other capital works, it was the Department of the Environment which could sanction them. For such schemes, a regional water authority could attempt to get parliamentary approval through a private Bill, but the complexities of the process meant that the preferred option was to apply for an Order under the Water Act 1945. This was then dealt with by the Secretary of State for the Environment.
