Biocidal Products Regulation and UK Legislation

Water UK considers that in due course, provided that drinking water is treated with an Authorised biocidal product whose active substance component is Approved and is on the Commission’s Union list and appropriate labelling is made via websites and other communication channels, then no further action is required for drinking water as a treated article. Where drinking water is treated with an active substance that is generated in situ from ‘commodity chemicals’, that in situ active substance will also be considered as the biocidal product.
