Sichuan Rubuchaka Drinking Water is a Chinese company specializing in the bottling of natural artesian water under the Rubuchaka brand. It was established in 2026 in Sichuan Province, China. The water comes from Rubuchaka in the Garzê Tibetan Autonomous Prefecture. Its source is located at an elevation of more than 3,700 meters in a mountainous area shaped by the geological processes of the Himalayas. The water emerges from deep fractures in granite rock through which it passes and naturally acquires its mineral content. It contains 195 milligrams of total dissolved solids per liter, placing it in the low-minerality category. Its pH value of 7.1 gives it a neutral character. It is particularly distinguished by its silicic acid content of approximately 97 milligrams per liter. The water also contains around one milligram of sulfate and two milligrams of chloride per liter. Its nitrate concentration is below 0.05 milligrams per liter, indicating a particularly low level of this compound. The water is still and positioned within the premium segment of the bottled water market. The name Rubuchaka is connected to the local spring and a legend about three sisters that forms part of the area’s cultural heritage. The company combines the water’s origin in a remote mountain region with a modern approach to production and international distribution.
