Environmental Stewardship

Sustainability is a core principle in how Castle Rock Water manages and operates our business to best serve our customers, care for the environment and ensure a strong water future. Our daily operations go beyond water protection and align business performance with commitment to environmental, social and community stewardship. Along with our Environmental Policy which states our purpose to protect the environment, Castle Rock Water has implemented an Environmental Management System to help manage operations and the environmental aspects associated with them.

First awarded in 2018, Castle Rock Water maintains the Gold status of the Environmental Leadership Program by the Colorado Department of Public Health and Environment for voluntarily going beyond compliance with state and federal regulations, and also for showing commitment to continued environmental improvement.

Environmental goals
Reduce the Town’s dependence on non-renewable water sources by reaching 75 percent of total water supply from renewable water sources by 2050
Reduce the number of Sewer System Overflows per year to zero and clean or inspect one third of collections system annually
Reduce overall water demand with a the goal of 100 gpcd by 2050
Optimize existing facility recycling program by increasing awareness and ease of recycling among CR Water staff
Reduce Overall Energy Consumption and continue the downward trend in kBTU per million gallons produced

Water conservation

Conserving water is a primary goal in any sustainability efforts, but for Castle Rock Water it also makes business sense. Saving water means the less we have to purchase in the future with less financial impact to our rate payers. Our goal is to reduce consumption of gallons per capita daily to 100 by 2050.


  • Reduced peak demand usage by assisting with increasing irrigation efficiency from top customers including Town outdoor facilities and non-residential customers
  • Water Use Management Plan – this demand management tool, revised in 2017, provides processes to ensure adequate volumes and pressure to the water distribution system during landscape irrigation season
  • Water Efficiency Master Plan – steps to encourage customers to use water efficiently
  • Water budget rate structure - tiered water budget with incremental rates to encourage conservation
  • Watering schedules - limited days per week and times during the day for residential and non-residential customer to irrigate, resulting in conservation and peak demand management
  • Landscape and Irrigation Performance Standards and Criteria Manual -- regulations for construction regarding landscape and irrigation design
  • Registration for Landscape Professionals program – required educational course on efficient irrigation practices for professional landscapers
  • Water Wiser workshops – free resident educational classes on efficient irrigation practices
  • ColoradoScaping courses – free xeric design workshops and demonstration gardens
  • Rebates and Customer Incentive programs - rebates for turf removal, select irrigation products, ultra-efficient toilets and whole house water monitoring systems to increase conservation practices 
  • Customer outreach -- messaging on the value of water in billing newsletter, social media and direct mail
  • Annual town-wide conservation campaigns -- spurring customer engagement with campaigns including the national Mayor’s Challenge, Parade of Gardens and ColoradoScape Contest

Watershed protection

One of our renewable water sources is surface water from Plum Creek. Prevention of hazardous waste entering our stream and keeping this source clean directly affects costs and treatment options. 


  • Source Water Protection Plan -- identifies risk and responses for activities and dangers that could affect surface water
  • Outreach for Douglas County Household Chemical Roundup, with chemicals collected including 19,600 pounds of pesticides and herbicides, 3,020 batteries, more than a ton of motor oil and over 44,000 pounds of latex paint collected and recycled
  • Annual Spring Up the Creek community-wide clean up with hundreds of  volunteers collecting trash on community trails and creeks
  • Pet waste pickup activities including sponsorship of dog waste station on Perry St. trail and outreach messaging
  • Promotional education for the unused medication drop off at the Town police station

Energy savings

An Energy Management Plan was developed in 2015 to focus efforts on ways to reduce electrical consumption, a primary cost center for pumping water from the underground aquifer and through distribution channels. 

Actions for electrical savings:

  • The implementation of Energy Management Plan in 2015 enabled Castle Rock Water to minimize increases in electrical usage while encountering an increase in water production. 
  • Transition away from pumping deep water wells, the primary electricity user for water operations
  • Time of use billing at all pump stations
  • Use of billing dates to effectively determine when to start and stop operations at well facilities
  • Use the most efficient billing rate to keep costs at their lowest
  • Involvement in the Town of Castle Rock Project Green program for energy savings within work areas including using blankets instead of space heaters, Turn It Off light switch reminders and anti-idling campaign.
  • Continued replacement of old, failing indoor and outdoor light fixtures with LED lighting
  • The O&M Building built in 2017 uses high-energy efficiency measures such as motion-sensor interior lighting

Actions for natural gas savings

  • Natural gas usage is for facilities only and not part of the business operations
  • O&M Building with high-energy efficiency measures was built in 2016 and accounted for a majority of the 6.7% decrease in gas usage
  • Project Green education on the use of clothing layers and blankets to accommodate temperature fluctuations within offices and buildings
  • Lowering thermostats in remote, unoccupied facilities to maintain temperature above freezing

Recycling efforts

Though Castle Rock Water hasn’t quite gotten to recycling water (yet), recycling efforts are primarily for retired equipment. Castle Rock Water also has a strong administrative recycling program within the office.

  • Recycling of all retired brass meters
  • Recycling of metal from various obsolete equipment and parts
  • Recycling of cardboard, including shipping boxes with on-site recycling bin
  • Recycling containers are used in personal office space and break rooms with continued education and reminders for use
  • Recycling of office supplies and equipment such as printer cartridges, copy paper, batteries, etc.
  • Participated in the Town of Castle Rock Project Green Team’s educating staff on what can be recycled in the recycling bins throughout all facilities  
  • Recycling of old toilets through our toilet rebate program
