Sounds like a way more expensive version of SoDis [0] Why use expensive copper when you could instead recycle, otherwise useless, PET bottles to do a similar job? The only potential drawback I can think off is that some PET bottles seem to leak "hormone-like chemicals" [1]. Tho, reading trough the comments copper pots also seem to have some toxic effect on the water.
