SUDS in the CIty-MA Landscape Architecture

1.3 The Management Train This is the basic framework that should be understood and which underlies the planning of any SUDS system. It is the hierarchy of systems that should reinforce and where possible follow the natural pattern of drainage, as set forth in ICOP (DEFRA, 2004a) (see Figure 1.11): 1.
Prevention – the use of good site design and housekeeping
measures on individual sites to prevent runoff and pollution (examples include minimising paved areas and the use of sweeping to remove surface dust from car parks), 2.
Source control – control runoff as near as possible to its source
(such as the use of rainwater harvesting, pervious pavements, green Figure 1.11 Showing the hierarchy of the Management Train. When ‘Prevention’ has been deemed impossible, you must first look to ‘Source Control’, then to “Site Control’ and lastly ‘Regional Control’. (source: RBA, 2010)
roofs or soakaways for individual houses). 3.
Site control – management of water from several sub-catchments
(including routing water from roofs and car parks to one large soakaway or infiltration basin for the whole site). 4.
Regional control – management of runoff from several sites,
typically in a detention pond or wetland.
