Chapter 1

Chapter 1 - of the guidance document will be prepared following the final secondment (M19) to bring together the findings in the context of recommendations to industry on water quality impacts, positive and negative, from flushing. This guidance will cover how the fundamental understanding of accumulation processes influences the design and implementation of flushing programmes along with provision of tools, techniques and approaches for water utilities to use to predict and manage flushing and possibly also to design DWDS for a future with no need for flushing.
