Securing long-term water for the Town and its residents is a primary goal for Castle Rock Water. Considering the drought in the early 2000s and the recent growth in Colorado, the Town has been continually and successfully working to ensure a long-term sustainable water supply.
In the past, Castle Rock and many South Metro communities have relied primarily on groundwater that comes from 1,000 or more feet below ground. This nonrenewable source in the Denver Basin aquifer is becoming difficult and expensive to extract. The plan is to move toward renewable water supplies, which is water in creeks and rivers that is replenished each year from snow and rain.
Whether importing water from other sources, managing peak demand during irrigation season or implementing new technologies, Castle Rock Water is well on our way to achieving 75 percent renewable water by 2050. Water customers can review long-term plans here.
