Castle Rock Water

Securing our future drop by drop


In 1900, the Castle Rock Journal highlighted our role as a leader in long-term water planning and conservation. After 130 years, Castle Rock Water continues this leadership role and takes
to heart its responsibility to protect and preserve the Town's precious resource.

We take our mission very seriously - to provide our community with exceptional service that protects public health and balances social, environmental and fiscal responsibilities in a sustainable manner.

Providing for our future


Castle Rock Water oversees the Town's water, wastewater and stormwater systems. Securing long-term  water for our future, drop by drop, is one of the most important goals that we strive to meet, and work towards every day.

Today, a large quantity (approximately 85 percent) of the Town's annual water supply comes from nonrenewable Denver Basin groundwater while only a small portion (approximately 15 percent) comes from renewable supplies along Plum Creek. The nonrenewable Denver Basin groundwater won’t last forever, so it’s important that we continue moving to a renewable water supply.

In accordance with our current plan, we are striving for a 75 percent renewable water supply by the year 2050. Learn more about our long-term renewable water plan.
