SEPA policy (1996) states that it is mandatory for new developments to provide SUDS on site: At source on individual premises; for conveyance and, also, on a regional basis. These SUDS features can serve the whole estate or a part thereof and are all part of the treatment train that consists of various levels of control, including source, local and regional controls. As part of the pollution risk management of the collective impact of an industrial estate, the day-to-day runoff quality and contingency planning functions for SUDS on individual premises and the road network can be vital, an approach consistent with the polluter pays principle. The focus of the research presented here was an industrial estate in Scotland. Runoff from the estate is polluted and discharges into the Caw Burn which is known to have water quality problems. Detailed visits to propose specific SUDS retrofits have identified opportunities at source on several premises, two possibilities for conveyance SUDS; and one opportunity for a regional detention basin. This paper explores the potential of a regional SUDS retrofit (public facility consisting of a detention basin and connecting swales) and provides a detailed insight into possibilities of retrofitting source control SUDS at a typical industrial premises. A number of combinations of various SUDS components (including permeable block pavements, pervious asphalt, swales, flow attenuation tanks, raised bed planters and detention basins) have been assessed as regards their functional characteristics, economic costs and logistical constraints. The most comprehensive retrofit would cost over £95,000, which may be prohibitive for a medium-sized company. A partial retrofit, however, is feasible: E.g. installation of raised raingarden planters and flow attenuation tanks would cost only a few thousand pounds. Adjacent to the premises, there is an extensive green space capable of accommodating a reasonably sized detention basin. Importantly, that could also serve a public road. Furthermore, several companies situated farther away could be connected to this feature by a conveyance swale. Ideally, such a basin would be adopted by Scottish Water and designed to alleviate consequences of a 100 years return period storm.
