Still water is water that is free of carbonation, meaning it contains no dissolved carbon dioxide gas and does not fizz or bubble. It is the most natural and commonly consumed form of drinking water, often sourced from springs, wells, or purified municipal supplies. Still water is valued for its clean, neutral taste and its role in maintaining hydration and supporting overall health.

It can be bottled or served straight from the tap, and is often preferred for its simplicity and lack of additives. Unlike sparkling or flavoured waters, still water is ideal for drinking on its own or accompanying meals without altering the flavour of food.
