I am delighted to listen to your 'conversation'. Policy does matter as you have emphasised, not only about tariff but also about mode of supply. In India, water supply is made intermittently, for a few hours a day. Apparently, this is to limit the loss in leakage from the distribution pipes. However, intermittent supply results in a tendency among consumers to pump out water directly from the pipes which puts them under suction. Deterioration of water quality is certain in such conditions. If leakage is nearly eliminated, water at the tap can be reliably safe for drinking. In that condition, the bottled water, domestic water purifiers and booster pumps over pipes shall become redundant removing more economic burden than the investment in leakage control.
