Association of Drainage Authorities, ADA

The ADA was established in 1937. Currently, Lord De Ramsey D.L. is President. The ADA now has approximately 200 members from England and Wales and has, among others, the following tasks:

  • To watch over and protect the interests of drainage authorities
  • To provide a forum for exchange of ideas, discussions and excursions
  • To lobby in the name of drainage authorities at the parliament
  • To obtain and disseminate information of common interest

The ADA is recognized as a main representative of Internal Drainage Boards in flood risk management and land drainage. It was a prime player in the formation, and a founder member of, the European Flood Control and Water Level Management Associations.

Drainage Authorities

Internal Drainage Boards are established under Act of Parliament to provide a flood risk management and water level management service. Their main tasks lie in low lying flood sensitive areas. The Environment Agency concentrates on the sea and tidal difiences, and the main rivers, while municipalities are in charge of more local urban needs.
The board of a drainage authority is composed of land owners, tenants and representatives of municipalities. They pay a certain levy which is the core budget of a drainage authority. Major projects are usually subsidized by the central government. Internal Drainage Boards were formed in their current arrangements under the Land Drainage Act 1930 and operate under the Land Drainage Act 1991.
