Current Castle Rock Watering Rules

Based on the official sources we reviewed, these are the published outdoor watering rules for Castle Rock Water. Confirm the current status with the official source before watering, especially during drought stages or emergency conditions.

What You Can Usually Do

  • Water on the published schedule: Every third day on the designated schedule symbol assigned by street address.
  • Use cooler hours: Before 8 a.m. or after 8 p.m. for residential customers.
  • Hand water where the official rules allow it, using a shut-off nozzle.
  • New plantings that need irrigation more often than every third day require a temporary watering exemption; the 8 p.m. to 8 a.m. time rule still applies.

What to Avoid

  • Water waste, including excessive runoff, can result in a watering violation.
  • Homeowner car washing is allowed with automatic shut-off nozzles, a bucket or sponge is recommended, and water waste is prohibited.
  • Failure to follow the watering schedule or incurring water waste can result in a watering violation.
