SuDS can take many forms and operate both above and below ground – some involve the use of landscaping whereas others include manufactured products such as our AquaCell units.

The type of SuDS chosen for a project depend on a range of factors. Traditional ‘SuDS thinking’ divided SuDS into two different types: soft (green) and engineered (grey).

Soft SuDS uses green landscaping to manage water within the site whereas engineered SuDS makes use of civil engineering structures such as culverts and underground tanks to manage water. However, recent changes in thinking now means many schemes incorporate elements of both soft and engineered SuDS within one holistic scheme.

The difference between these two types of SuDS was explored in our webinar with Building Magazine which you can listen to here.
