You may need permission to work on main rivers and other watercourses.

When permission is needed

Permission may be required for:

  • works in, over, under, a watercourse (including both temporary and permanent works)
  • raising ground levels near a watercourse
  • constructing or altering a culvert or structure to control the flow of the river (such as a weir) on any ordinary watercourse
  • new surface water discharges to watercourses
  • culverting an open watercourse

What type of permission is needed

If your work affects a main river you may need an environmental permit from the Environment Agency.

If your work affects another type of watercourse you may need land drainage consent from the council.
