Section 25 of Land Drainage Act 1991

The Land Drainage Act 1991 sets out the functions of boards and local authorities in relation to land drainage.


As of 6 April 2012 we gained certain powers under the Land Drainage Act concerning enforcement on ordinary watercourses.

We now have permissive powers under Section 25 of the act to ensure that appropriate maintenance is carried out by riparian landowners on ordinary watercourses. These powers can be exercised if it is deemed that a lack of maintenance or an alteration to a watercourse pose a flood risk.

Therefore, if a landowner carries out actions that adversely impact on the flood risk to another landowner’s property, we have the right to serve a legal notice on the responsible party to carry out remedial work to resolve the issue. It should be noted that these powers are permissive and are not a duty and as such the exercising of these powers is at our discretion.

In the first instance after being informed of a possible infringement by a landowner, we will seek to gain that landowner’s cooperation in ensuring appropriate maintenance takes place. We will carry out site investigations, advise all parties on their duties under the Land Drainage Act and co-ordinate discussion and communication between relevant parties.

Exercising of permissive enforcement powers will only take place when necessary and as a last resort when all other opportunities to resolve the issue have been explored.

We have produced a policy document which provides a public statement on our approach to the use of our powers under the Land Drainage Act 1991. We will use this formal protocol when deciding which works require investigations and possible enforcement and to which cases we give priority on a county wide basis.

Enforcement powers

Once we have decided that enforcement action is necessary, our next steps are to:

  1. Advise the responsible party in writing that they must carry out the necessary maintenance works within a specified time.
  2. If the works are not carried out in the specified time, we may serve a notice under Section 21(2) of the LDA requiring the nuisance to be abated. Where an infringement poses a serious flood risk, the first step may be bypassed and the legal notice may be served immediately.
  3. Where there is non-compliance with the Section 21(2) legal notice, we may then have the power under Section 21(4) of the Land Drainage Act 1991 to carry out the remedial works and recover the costs of the works from the responsible party.
