Even affluent Indians drink boiled/filtered water drawn from wells. It was a surprise to me that in many European countries one could drink straight from the tap. A even bigger shocker was to know that the same water is used for flushing toilets. Treating water to make it drinkable is extremely energy intensive. Making small tweaks to our current setup without a discernable lowering of quality of life is just not comparable to making access to drinking water more expensive.
