Where does your water come from? It depends on where you live and how you are using the water. Your water might come from the ground beneath your feet, pumped to the surface by a well. Or it might come from a local river. Or the water may come from hundreds of miles away, even crossing the continental divide, to arrive at your tap.

Many Coloradans live far from the source of their water. For example, the largest storage facility for Denver Water, which serves metro Denver, is Dillon reservoir. This reservoir collects water from the Blue River, which is then sent through the Harold D. Roberts tunnel, under the continental divide, and into Denver for use.

If you’re curious to determine the exact source of your water, look for the “Water Quality Annual Report” or “Consumer Confidence Report” published by each large treated water provider. You can also request reports from smaller water providers. These describe drinking water sources used and may provide a map of the water collection system.
