Why Castle Rock Chooses Eldorado Spring Water
Naturally Filtered. Award-Winning Taste. Colorado-Owned.
For over a century, our water has traveled through layers of ancient sandstone deep beneath the Rocky Mountains—naturally filtering and collecting essential minerals along the way. The result is clean, crisp, balanced spring water with a taste Castle Rock residents consistently rank above tap and purified water brands.
Sourced in Eldorado Springs and delivered directly to homes and businesses across Longmont, our water brings the freshness of the Rockies straight to your door.
