Strategic retrofitting
Resolving flooding and water quality problems by delivering SuDS, different types of systems to those used in the past, requires planning to work out what can be retrofitted where. This work will need to be done on a catchment-wide basis and a systematic (strategic) approach will need to be adopted.
For strategic retrofitting to be successful it is important to understand the underlying cause of the problem that is being dealt with. In urban areas the effects of flooding or water pollution are often remote from the source of the problem. Urban drainage systems can also be complex.
Computer modelling can help to build an understanding of the link between cause and effect, and this will then lead to robust solutions. However, climatic and other changes in the future may mean that the causes and effects of future challenges shift and now require solutions that can be adapted in the future.
