Ordinary watercourse consenting

You need permission to work near a stream or river.

On April 6, 2012, the Environment Agency Wales gave its flood defence powers to local councils.

NPTCBC is now in charge of flood defence and watercourses in the area. Main rivers and coasts are still managed by Natural Resources Wales (NRW).

If you want to work near a stream or river, you need a permission called an Ordinary Watercourse Consent (OWC), which is in compliance with section 23 of the Land Drainage Act 1991.

This is to make sure the work does not cause flooding, pollution, or harm to wildlife.

There are two types of permission you might need:

  • Permanent Consent: For building things like bridges or weirs that will stay in the water.
  • Temporary Consent: For things like sandbags or barriers that will be moved later.

It's a good idea to talk to NPTCBC before applying to avoid mistakes. Once you apply, it takes two months to get permission.

Remember, you might also need other permissions from the Environment Agency or landowners.

To apply for consent, please complete the Ordinary Watercourse Consent application form.
