Our water


We don’t treat our water because we don’t need to.
Our water is untouched at source producing water of unrivalled quality and taste.



Straight from the south downs

South Downs Water is drawn from an artesian well located 420ft below ground level just outside the historic city of Chichester, on the border of Sussex and Hampshire, UK. 

Since discovering the source over 30 years ago, we’ve been on a mission to share our award-winning water along the South Coast and beyond. 

Why drink water from anywhere else when you can have refreshingly pure water from your doorstep? 


In order to share our wholesome water with as many people as possible, we’ve made sure South Downs Water is available in a variety of different volumes. From 19l office water coolers through to glass and 100% recycled plastic 330ml on-the-go sizes, we deliver directly to offices, hotels, restaurants, venues, pubs, schools and private homes across. We also use regional distributors for orders from further afield – find a list of distributors on our stockists page.


It’s no secret that we love the South Downs. Being ever-thankful to our provenance for providing us with the very best water, we’re constantly looking for ways to package and deliver our water in the most sustainable ways. In addition to glass bottles, our plastic 330ml and 500ml bottles are made from 100% recycled materials. Find out more about our extensive sustainability initiatives on our dedicated blog page. 


We don’t add any nasty treatments or chemicals to our water because we don’t need to. 

Enriched with minerals from deep within the South Downs, our water holds the prestigious Natural Mineral Water Status meaning that, unlike Spring Water, it is untouched and untreated when bottled at source. 

Why? Thanks to the wonderfully deep chalky layers of the South Downs, our water is filtered naturally and has a stable composition without need for any artificial treatments. The only exception we make is when adding a touch of refreshing bubbles to our sparkling range.

The result is exceptionally fresh water that’s naturally high in calcium and low in sodium and unrivalled in quality. As pure as nature intended.



Natural Mineral Water

Natural mineral water must come from an identified and protected source. It is guaranteed to be consistent in composition and naturally wholesome without any treatment – except in some cases the addition of carbon dioxide to make the water sparkle. Natural Mineral Water status is only granted to waters that are demonstrated to be free from pollution and have a characteristic stable composition.

Spring Water

Certain treatments are permitted for Spring Water.

Our water is regularly tested to ensure that the high levels of purity are maintained.
