Water conservation rebate programs
The Town of Castle Rock adopted the Water Conservation Master Plan in 2006, with a goal of achieving a water savings of 18 percent (165 to 135 gallons per capita per day) through various programs. Rebates can be honored only once per household on a first-come, first-served basis, while funds are available.

The following is a list of available rebates.
