Watercourses, Ditches and Streams
Watercourses, ditches, streams
Land owners are responsible for any watercourse that runs on or under their land, and usually up to the centre line of any watercourses on the boundary of their land. The Deeds of the property will also provide details of the land owner’s responsibility.
This land owner responsibility is known as Riparian Ownership.
A watercourse can be known as a:
- Rhyne or
- Culvert (an underground structure that a watercourse can flow through)
The Environment Agency has created a guide on Owning a Watercourse for those responsible for watercourses on their land.
Works in and around ditches and streams
Any changes made to a watercourse that will affect the watercourse require permission. This can include putting the water into a pipe (known as culverting), installing a bridge or building a headwall. Even temporary work that will affect a watercourse, like temporarily blocking it to clear mud, will need permission.
Works on Main Rivers require permission from the Environment Agency. You can check if the ditch you’re responsible for is a main river by checking the Environment Agency’s main river network map.
If you need permission from the Environment Agency guidance is available online at Flood risk activities: environmental permits.
An Ordinary Watercourse is any ditch, stream or such like that is not designated as Main River. Works affecting an Ordinary Watercourse require permission from the Lead Local Flood Authority which in Mid Sussex is West Sussex County Council.
