States that the clause appears to be unnecessary. ‘Effectively disinfected…’ is simply a means of achieving the required (microbiological) water quality (which is not defined in the clause anyway, unless effective disinfection is meant to mean sterility – which is unnecessary). The second part of 18(a) already requires the water ‘continue to satisfy those conditions during the course of the wet storage’. Disinfection could well be the means of achieving this requirement, but not necessarily the only means of doing so.
