Making changes to a watercourse

As Lead Local Flood Authority (LLFA), Hampshire County Council is responsible for giving permission for works on ordinary watercourses

An ordinary watercourse is a watercourse that is not part of a main river. It includes rivers, streams, land and roadside ditches, drains, cuts, culverts, dikes, sluices, sewers (other than public sewers within the meaning of the Water Industry Act 1991) and passages, through which water flows.
Hampshire County Council’s responsibility

You must apply to Hampshire County Council for consent to carry out work which may:

  • place or alter a structure within an ordinary watercourse
  • affect the flow or storage of water within an ordinary watercourse

This includes temporary structures.

If your watercourse is part of a main river then you will need to apply for the consent of the Environment Agency for any proposed works
When consent is required

Check the guide to ordinary watercourse consenting to see if your works need consent.
