The study was carried out to establish the extent to which source-control s
ystems are being used in Scotland. An investigation into the level of knowl
edge of such systems was also initiated. Over 100 questionnaires were sent
to organizations which have been involved in the development of surface-wat
er drainage schemes, and the 43 responses were analysed.
Further work was then undertaken to establish the locations of source-contr
ol systems in use. The collated information was utilized and, with the help
of the Scottish Environment Protection Agency consent files and correspond
ence with consultants, a database indicating the locations of sites, was co
mpiled. Information was collected on approximately 79 examples of such syst
ems, currently in use or proposed, in Eastern Scotland.
