Coca-Cola uses water from local municipal water supplies,[2] filters it using the process of reverse osmosis,[2] and adds trace amounts of minerals, including magnesium sulfate (Epsom salt), potassium chloride and sodium chloride (table salt).

Coca-Cola announced that they would be distributing Dasani water in new packaging comprising 30% plant-derived plastics.

Unlike other plant-based packaging, the bottles are compatible with standard recycling plants and represent up to a 25% reduction in carbon emissions compared to standard water bottles, though this still represents an energy consumption two thousand times that of tap water.

The Calgary and Brampton plants produce Coca-Cola's plain-water (Dasani) and sugar-water (soft drinks) products.

It was also released under the name Ciel Dasani in Mexico in four flavours: lemon-cucumber, papaya-carrot, grapefruit and mandarin-green tea, but it was discontinued in 2006.

By early March 2004, the mainstream press had picked up the story [7] and it became widely reported that Sidcup tap water, after being processed, was being sold under the Dasani brand name in the UK.

Coca-Cola immediately recalled half a million bottles and withdrew the "Dasani" brand from the UK market.

[9] The launch, and later contamination scandal, drew comparisons in the press with a 1992 episode of popular sitcom Only Fools and Horses, "Mother Nature's Son" in which lead character Del Boy (David Jason) hatches a scheme selling tap water bottled in his council flat in Peckham—nine miles from Sidcup.

[13] Places Dasani sources its water from include: California,[14] Minnesota,[15] Arizona,[16] Colorado,[16] and Michigan.

[19] This filtration process consists of a multi-barrier treatment system,[20] reverse osmosis, and nanofiltration to remove impurities.

[21] Coca-Cola claims that this process provides a consistent taste,[21] though the content within the bottles may vary across the world, depending on their source, despite frequent testing to ensure they meet FDA standards for purified water.

[26] In 2019, Coke announced Dasani Purefill, a program in which customers can refill their bottles with filtered water for free.
