Apply for land drainage consent

Land drainage consent is required if you are planning to carry out works on an ordinary watercourse. Ordinary watercourses are passages of water that do not form part of a main river. This can include streams, ditches, drains, mills, dams, culverts, and weirs.

You can contact us in advance to discuss your requirements


Identify type of watercourse

You can apply for consent for ordinary watercourses through us.  

If you'd like to carry out work:

If the watercourse you are looking at is not shown on the map below, please assume it is an ordinary watercourse.


Culverting an ordinary watercourse

We are the consenting authority under Section 23 of the Land Drainage Act 1991 for erecting a culvert in an Ordinary Watercourse. Our policy has been adopted to prevent the unnecessary culverting of Buckinghamshire's ordinary watercourses due to the adverse effect on the environment. This includes:

  • exacerbated risk of flooding
  • increased maintenance requirements
  • difficulty detecting pollution
  • destruction of wildlife habitats
  • damage to natural amenity

Before applying for Land Drainage Consent, please ensure you read our Culvert Policy.


Land Drainage Enforcement Policy

The Land Drainage Act gives us power of enforcement if work has been done in a watercourse without consent.

For more information, read our Land Drainage Enforcement Policy.
