Environmental problems Flooding for business and land owners

Apply for consent: works affecting watercourses

You need to have consent from us if you propose to connect surface water to an ordinary watercourse (a watercourse which is not classified as main river) or intend to make any alteration of that watercourse as part of your development.

Certain types of work may not be permitted due to the potential increase in flood risk, we can issue consent for a proposed scheme by checking that it does not increase the risk of flooding and that it does not adversely affect the environment.

This applies to both permanent and temporary works affecting a watercourse. Temporary works could be the damming of a watercourse to allow permanent work such as the installation of a bridge.

If you are not sure if your proposals needs consent or if you want advice to carry out a scheme then contact us first at floodriskmanagement@manchester.gov.uk as often work may be undertaken in more than one way.

Obtaining consent

You need permission from the appropriate body - is the watercourse an ‘ordinary watercourse' or 'main river'?

Depending on your proposals, a conditioned consent may be given for you to carry out the work, for example a certain time of year, in order to reduce flood risk and potential ecological damage.

Consent is valid for a maximum of three years.

Sufficient information must be included so we can determine the suitability of your proposals. You must demonstrate that your proposals will not have an adverse effect on flood risk or the environment.

Your application will be determined within two months of receiving a valid application (valid application includes a completed form, details of your proposals and the fee).
