Source control

Dealing with water when and where it falls (source control) may be the preferred, cheaper and easier option for many developments. By dealing with runoff at source the volume of water and the potential amount of contamination is less, which requires smaller SuDS components further downstream. Often source control components are within the curtilage of properties and maintained by the property owner or manager and can include green roofs, permeable surfaces, rainwater harvesting and water butts.
