Castle Rock Has $750K in Water Rebates Available

By Connor Tien, DougCo Social

Castle Rock Water just approved $750,000 in conservation rebates for 2026. First come, first served until the money runs out.

What Qualifies

You can get money back for:

  • ColoradoScape conversion β€” Replace grass lawns with water-wise landscaping
  • Rotary irrigation nozzles β€” Upgrade from fixed-spray heads to more efficient rotary nozzles
  • Ultra-high-efficiency toilets β€” Replace older toilets with ultra-efficient models

How to Apply

Apply online at CRconserve.com/Rebates. Rebates are offered on a first-come, first-served basis until funding is exhausted.

Why It Matters

This isn't just about saving money on the rebate. Castle Rock Water saw its lowest gallons-per-capita-per-day usage in 2025 since tracking began in 2007. These rebates work.

If you've been thinking about replacing that thirsty lawn or upgrading your irrigation, now's the time. The funding is finite and tends to go fast.

What Changed for 2026

The whole-home water-monitoring system rebate has been discontinued. Everything else remains the same as previous years.
