Weed Wiper Partnership

Whilst best practice information is available to everyone, the weed wiper trial is only available in two river catchments.


If you're unsure if your holding is within the catchment and would like us to check, please email your address or land details to watersource@dwrcymru.com.

What is a river catchment?

river bankIn this context, a catchment is the term used to describe the area of land where water drains to or collects.

After rain, water flows over the land, though soil and rock, into streams and eventually the main river. The boundary of a catchment follows natural slopes, hills or mountains within a landscape and determine if water flows into one river or another.

Every inch of land on the Earth forms part of a catchment – big or small.
