Have You Got the Bottle?

It may seem obvious, but 'experts' have suggested that one way of countering the growing mountain of plastic waste, contaminating land and sea, is to greatly improve the water supplies to buildings in developing nations (https://www.theguardian.com/environment/2020/may/27/improve-water-supply-in-poorer-nations-to-cut-plastic-use-say-experts). When the domestic supply is contaminated (or even perceived as potentially contaminated), people often buy their water in plastic bottles. Improving the supply from the taps, might well reduce these purchases but we would also have to overcome the effects of marketing. At present, bottled water can be presented as a) more tasty; b) full of health-boosting minerals; c) a more effective means of rehydration (highly dubious) or d) simply a smarter, more upmarket option (although these last versions tend to be in glass bottles).
