Development Control Service

One of the principle services that we provide is regulating, controlling and facilitating development to secure the efficient working of the drainage system now and in the future. This is done by reasonable application of the Board's Byelaws and the Land Drainage Act 1991, and by working closely with the Developers, Local Authorities, Environment Agency and other Stakeholders.

Planning/Byelaw Policy and Guidance

The Board’s Planning and Byelaw Policy sets out how we will control development that would otherwise compromise the efficient working of the drainage system within the Drainage District. Guidance is also available to help you complete your application, together with the Board’s charging policy. As a rough guide, if you wish to do any of the following you will require the Board’s prior written consent:


Alter a watercourse by culverting, bridging, installing a control structure, filling-in or changing its existing course;

Discharge surface water into any watercourse;

Discharge treated water (effluent) into a Board’s main drain;

Build or plant within 9 metres of a Board’s main drain;

Attenuate surface water run-off arising from development.


Further Information

If you would like any further information on whether you need the Board’s consent to do something or on how we will consider your application, please contact the Group’s Catchment Engineer.


Application Forms

To apply for consent your application should be completed and returned to us:

Application for a relaxation of Byelaw 10
