Paragraph 12 Surface and foul water drainageI1

No part of the authorised development may commence until, for that part, written details of the surface and foul water drainage systems (including means of pollution control) have been submitted to and approved in writing by the relevant planning authority in consultation with the internal drainage board, the Environment Agency, the Lead Local Flood Authority, the F1Canal & River Trust, and NRIL, as appropriate.

The surface and foul water drainage system must thereafter be constructed in accordance with the approved details before the operational phase of that part of the authorised development commences.
