Paragraph 27 Drainage: surface water and foul drainage worksI1

No construction of the development must commence until details of the surface and foul water drainage system (including means of pollution control, details of water management zones and a programme of construction and implementation) have been submitted to, and approved in writing by, the local planning authority.

Unless otherwise provided pursuant to the site preparation works permission or a development consent order for a new nuclear generating station at Hinkley Point, any fresh water discharge associated with the development must discharge to the existing Hinkley Point C drainage ditch at the location identified on the drawing referenced figure 13.1 in the environmental statement submitted with the application for this Order following attenuation to greenfield run-off rates and treatment within a dedicated water management zone.

The surface and foul water drainage system must be constructed, maintained and retained in accordance with the approved details.
