Castle Rock Has Some of Colorado's Hardest Water
Castle Rock's water supply comes from the Plum Creek Watershed and the Denver Water system, resulting in water hardness levels typically between 15-20 grains per gallon (GPG). This is considered "very hard" water that wreaks havoc on plumbing, appliances, and fixtures.
