Surface Water Drainage Strategy, Layout, and Design
We are able to design surface water conveyance and attenuation systems for all scales of development. Since the introduction of Planning Policy 25 (PPS25), Sustainable Urban Drainage Systems have become integral to all scales of development within the UK. Routinely, the Local Planning Authority will require the calculated peak flow runoff from the pre and post development site, means of attenuating post development surface water flows to existing discharge rates, and methods of onsite storm water storage.
