Colorado water districts are paying Front Range homeowners to upgrade their irrigation systems — and 2026 has more active programs than any year prior. But the details matter: rebate amounts vary from $45 to fully free installs depending on your city, programs open and close throughout the year, and most require a certified installer to qualify.
We track every active program on the Front Range so our customers don't leave money on the table. Here's what's confirmed as of March 2026.

How do rebates actually work?
Most programs follow the same basic process: you install a qualifying smart controller (typically a WaterSense-certified model like Rachio), submit proof of purchase along with an application to your water utility, and receive a rebate as either a check or a credit on your water bill. Simple in theory — but in practice, the paperwork requirements, eligibility deadlines, and qualifying product lists trip people up.
A few things that commonly disqualify applications:
- Installing a non-Pro or non-WaterSense model that isn't on the utility's approved list
- Submitting after the program's fiscal year closes (most programs run calendar year)
- Missing a photo requirement or account number on the application
- Installing yourself when the program requires a licensed contractor
Do I need a certified installer to get the rebate?
It depends on the program. Broomfield, Thornton, and Erie accept self-installs as long as the product qualifies. Lafayette and Louisville's free programs through Resource Central require booking through their certified installer network — which is where we come in.
Beyond eligibility, there's a practical argument for professional installation: the Rachio Pro Series controller (the model we install) qualifies for a 4-year warranty when installed by a certified Pro, versus 2 years for DIY. That extra warranty alone is worth more than the cost difference on most jobs.
When do programs close?
Most utilities fund rebates out of an annual budget, which means programs run out of money before the year ends — sometimes as early as August or September. Lafayette and Louisville's free install programs are especially limited and historically fill up within weeks of opening.
The safest approach is to schedule before summer. If you're in a city with an active program, waiting until July or August means the budget may be gone.
