Learn to Conserve

Castle Rock Water provides opportunities to learn how to become more efficient with your water usage. Workshops are scheduled at various times from March through September with schedules usually posted in February. Programs, such as classroom presentations and water treatment plant tours, are available year-round.


Water Wiser Workshops: Smartscape Solutions

Did you realize you could be wasting between 20 and 75 percent of your sprinkler water? All sprinkler heads are not created equal and over watering is the primary cause of unhealthy plants. With approximately 50 percent of household water used for maintaining landscape, this workshop shows how easy it is to improve the efficiency of your sprinkler system, detect water waste and better understand your landscape watering needs.
Completion of this free workshop earns you a “Water Wiser” designation and exempts you from the every-third-day watering schedule. Workshops are held throughout the irrigation season at varying times and locations.

The workshop schedule is available in February. There is no charge to attend the workshops; however, registration is required.

Xeric Design Workshop

Xeric design is not the creation of harsh and stark landscapes, but the addition and placement of low-water-use plants. The “Principles of Xeriscape Design” focuses on Colorado xeriscape style and provides design ideas that are aesthetically beautiful and diverse while also great for the high, arid climate of Castle Rock. The workshop outlines the benefits of low-water-use plants, watering considerations and design layouts; as well as provides the top 10 trees and shrubs that thrive in Castle Rock.

Two classes are held in May to June. Registration is required.

Winterization Workshop

Wonder why some yards just seem to perk right up in the Spring? It’s winter preparation. In addition to demonstrating the importance of reducing water use as temperatures decline, this workshop identifies areas of yard maintenance that are often overlooked - including seasonal fertilization, pruning, mulching and aeration.

Registration is required. One class is held in September.

These workshops are presented by Water Conservation Specialist Rick Schultz, who has over 30 years experience in landscape and irrigation maintenance in both the public and private sectors; and Water Conservation Plan Reviewer Ruth Stadler, who in addition to her M.S. in Horticulture has more than 20 years of experience designing and building xeriscapes. 


School classroom programs

These programs teach students about the water cycle and how it specifically relates to Castle Rock. Our Water Conservation Specialist Rick Schultz will come to your classroom and provide a 60 to 70 minute interactive presentation directly relating to several Earth Science Standards (fifth and sixth grade).

The students are able to not only learn about water as a resource, but participate in hands-on activities for deeper understanding, and relating that knowledge to where they live.

The presentation includes:
  • The water cycle
  • Where Castle Rock gets its water
  • Groundwater and surface water-renewable and nonrenewable resources
  • Stormwater and water quality - the impact of human civilization
  • Importance of conservation - and our Town’s goal
  • Students help build an aquifer in a fish tank
For questions and more information about scheduling a presentation at your school, please contact us.

Plum Creek Water Purification Facility tour

Watch your water get treated by touring the Town’s state-of-the-art Plum Creek Water Purification Facility - one of the Town’s Legacy Water Projects. The facility’s unique design uses a five-step treatment process to purify both groundwater and surface water:
  • Chemical pretreatment
  • Flocculation / sedimentation
  • Greensand filtration
  • Membrane filtration
  • Post-filter chemical treatment
Want to know what all of those steps entail? See them in action during tours of the facility. Tours are held at 10 a.m. the fourth Wednesday of each month, and last about one hour. There is no cost for the tour.

Reservations and appointments are required. Complete the reservation formor call 720-733-6000. Special tours can be scheduled for groups larger than 10 people.
