What are Highlands Ranch’s water entities?

Where does our water come from? 

Highlands Ranch residents are fortunate to have two water supply sources - the South Platte River to the west and a massive aquifer underlying the region. Centennial Water combines supplies from both sources to optimize the reliability, quality and cost-effectiveness of water. This joint use of renewable water combined with the vast underground aquifer allows Centennial Water to operate a true conjunctive use system.

How does HRCA encourage wise conservation of water?

The HRCA encourages property owners to conserve water through established and proven water conservation techniques. However, property owners are required to maintain their landscaping at the same time. A stressed lawn during times of drought is acceptable, but dead and dying lawns still require maintenance. The HRCA recommends that property owners follow the watering schedule from the Centennial Water and Sanitation District.

How water-conscious are Highlands Ranch residents?

The Residents of Highlands Ranch are responsible when it comes to protecting the environment. Some residents like the idea of owning a smaller lot, which requires less water to maintain, and enjoy the surrounding natural open spaces that require no irrigation. Many newer homes in the area also have been constructed with water saving devices such as low volume toilets and water saving showerheads.

What are some common lawn maintenance tips?
  • Don’t water on a set schedule. The need for water can vary greatly from one day to the next. Most lawns can tolerate being watered every three to five days (some longer).
  • Use the manual, rather than automatic, setting on an irrigation system.
  • Water when footprints or mower wheel tracks become easily visible on the turf and large areas of the lawn turn bluish gray.
  • Apply three quarters to one inch of water, slowly enough that runoff and puddles do not occur. Sprinkling different areas in sequence helps water soak into the lawn more thoroughly and evenly. Don’t water again until you see abundant signs of water stress.
  • Hand watering small, isolated dry spots can enable a lawn to go another day without being watered.
  • Water between 9 p.m. and 9 a.m., when it’s cooler and there is less wind.
  • Avoid heavy or frequent nitrogen fertilization.
  • Grass that is lush is more likely to be damaged if watering restrictions are imposed. Lush, fast growing grass uses more water.
  • Set your mowing height at 2 ½ to 3 inches, or as high as possible. Don’t remove more than three quarters of an inch of grass in any mowing. Use a sharp blade to reduce tearing of the grass leaves.
  • Be willing to accept a less than perfect lawn.
