This is the info I found online at www.kepwel.com.
“Kepwel Natural Spring Water comes from deep in the ground after it travels many miles through rock and sand being naturally filtered along the way. Then by the forces of nature it comes up into our protected tiled spring house shown below (circa 1920). From there it is pumped directly to our bottling plant, located only 100 yards away. After being filtered for natural sediment and tested, we bottle our spring water daily, so you get only the freshest, pure natural spring water available delivered to your home or office. Our family has been enjoying the great taste of Kepwel for 5 generations.”
