Ordinary Watercourse Regulation

We issue all land drainage consents for works to watercourses (streams and ditches both natural and man-made and culverts etc) within the City and County of Swansea.

Apply for an Ordinary Watercourse Consent

Application form and guidance notes for Ordinary Watercourse Consent (PDF) [285KB]

If you are concerned about works to an ordinary watercourse in your local area then you can email us at to determine whether the works required consent, and whether an application for consent was made or not.

We will take a risk-based approach to enforcement where unconsented works have been carried out on ordinary watercourses. The purpose of ordinary watercourse regulation is to control certain activities that might have an adverse flooding impact. 

Investigations into flooding

As the Lead Local Flood Authority (LLFA) for our City and County, one of our responsibilities is a duty to investigate flooding that occurs within the county as we deem necessary.

Local flood risk management strategy

The local flood risk management strategy will be developed by the council to balance the needs of communities, the economy and the environment.

Flood advice

Useful information if your home is threatened by flood water, or in the event of a flood.
