B4.6 Water Legislation in the UK


Legislation in the UK is divided into different areas. Legislation affecting:

  • England and Wales.
  • Scotland.
  • Northern Ireland.


Please note that the following section provides details of numerous pieces of legislation. It is not necessary for you to remember them all.

They have been provided to give an overview of the sorts of issues that are covered by legislation, which you can see are wide-ranging.

Each organisation has legislation that is considered ‘key’, but this differs from organisation to organisation. For example, legislation covering Controlled Waters is ‘key’ if you work next to or discharge into controlled waters, but it is not relevant if you do not!

The information in section B4.9 Operational Implications of Water discusses in more detail what are generally considered the key requirements of water legislation for many organisations.


You do not need detailed knowledge of legislation for the exam.
