The Inlands Farm site is characterised by open fields interspersed with ditches and ponds which route surface water towards a culverted watercourse beneath The Marsh and onwards to The Liden Brook, a tributary of the River Cole.
It is known that the site sees standing water on the surface in winter from overland flows and springs towards Wanborough which Swindon Borough Council has identified as a flood risk.
The Science Park will mimic the natural water environment of the area to the philosophy of Sustainable Drainage Systems (SuDS). This will ensure that the proposed development will be protected from flooding and will also not increase flood risk to other properties or the wider River Cole catchment.
The sustainable drainage system will:
Limit surface water runoff to current greenfield levels to mimic current release to watercourses
Limit flood risk to neighbouring areas
Utilise at surface systems like swales and existing ditches to:
Improve surface water quality
Enhance the green space (amenity value)
Store water in attenuation features such as:
‘Dry’ detention basins
Porous paving in carparks
