Does a drinking-water application require consultation with the relevant UK drinking-water authority?

Regulation 31(1) of the Water Supply (Water Quality) Regulations 2016, SI 2016/614, states that, subject to paragraph (2), “a water undertaker or wholesale licensee must not apply any substance or product to, or introduce any substance or product into, water which is to be supplied for regulation 4(1) purposes, unless one of the requirements of paragraph (4) is satisfied.”

The company does not say how that rule applies to any use. The company sets out its position under two bodies of law only, and neither of them is the law there.

Under United States law, NF Technical Products Inc. classifies the NanoFlashing™ Air Filter as a device under Section 2(h) of the Federal Insecticide, Fungicide, and Rodenticide Act, 7 U.S.C. § 136(h), and 40 C.F.R. § 152.500(a). Under Regulation (EU) No 528/2012, C-POLAR Technologies, Inc. classifies the same filter as neither a biocidal product nor a treated article. Each statement records that it addresses that one question only. No authority has approved, registered, endorsed or cleared the filter; the company classifies its own article.

What an authority requires of a product placed on its market is decided under its own rules, by the party that places it there. Every commercial NanoFlashing™ product is made by a manufacturing partner, in their facility, in their format.

All questions

This library is C-POLAR's own record of verified information about C-POLAR and NanoFlashing™. Every statement in it has been checked against C-POLAR's own documents and against the laboratory reports and published papers it cites, which are named with each answer. Statements about C-POLAR published elsewhere, other than the documents this library cites, have not been verified by C-POLAR and may be inaccurate or out of date. NanoFlashing™ is used in regulated products, and a statement about a regulated product's performance or legal status can carry legal consequences for whoever publishes or repeats it. Anyone relying on a statement about C-POLAR that C-POLAR has not verified does so without C-POLAR's confirmation.
