The company uses the mains supply to its factory in Sidcup, southeast England, as the source for its new "Dasani" bottled water, the Daily Telegraph said. Coca-Cola has put a designer price of 95 pence (1.4 euros, 1.7 dollars) for 500 millilitres of its bottled product, which comes in bright blue containers suggesting idyllic fresh water scenes, The Times reported. British water company Thames Water, meanwhile, charges its customers just 0.0316 pence for the same amount through the tap, The Times noted. Marketing for the Coca-Cola product says its water goes through a "highly sophisticated purification process". One stage, called reverse osmosis, is described as a technique perfected by NASA (news - web sites) to purify fluids on spacecraft. Calcium, magnesium and sodium bicarbonate are then added for taste, according to Coca-Cola, whose marketing slogan is: "It's the real thing". "The point is quality rather than provenance," a spokeswoman told the Telegraph. But the British water industry said the product's implication seemed to be that local tap water was impure. Barrie Clarke, spokesman for UK Water which represents suppliers, said: "We don't think there are any impurities in tap water. People don't need to buy this stuff to get excellent quality, healthy water." PIN/AFP
