Chapter 3

Chapter 3: of the guidance document will be prepared following the final secondment (M11) to summarise the scientific evidence to support (or reject) the use of certain practices for DWDS maintenance and repair. A key element of this chapter will be to summarise the different practices recommended by local, regional, or national regulators and professional associations to understand how this research could be implemented more widely across Europe, and whether changes to practices should be pursued to ensure safe drinking water.
