High-Efficiency Toilet (HET) Rebate

Download a toilet rebate form (PDF) or pick one up at the Water Services office on the second floor of City Hall at 211 W. Aspen Avenue. Forms must be filled out completely, signed, and dated. Legible receipts, photos of the date stamp inside the tank of the old toilet, along with the old and new toilets as installed in your bathroom must also be submitted. Below are the rules for the high-efficiency toilet rebate:
  • Single-flush toilets must use 1.28 gallons or less per flush; dual-flush toilets can use 1.0/1.1 to 1.6 gallons per flush.
  • All devices must be EPA WaterSense® labeled.
  • Toilets must have been purchased on or after June 1, 2016.
  • New toilets must replace an existing toilet; only homes built before 2009 (as noted in the Coconino County Assessor’s parcel database) are eligible since the City code required high-efficiency toilets after that date. Commercial sites built before 2011 are also eligible.
  • You must be a current City of Flagstaff water meter customer.

Rainwater Harvesting Tank Rebate

City of Flagstaff water metered customers can apply for a one-time $100 credit on their utility bill by installing new rainwater harvesting tank(s) that have at least a 1,000-gallon capacity. The tank(s) must have been purchased on or after June 1, 2016. An on-site inspection of the tank(s) by City of Flagstaff water conservation staff is mandatory prior to processing the rebate. Download a rainwater harvesting rebate application or pick one up on the second floor of City Hall in the Water Services office at 211 W. Aspen Avenue.

Low Water Landscaping Rebate

Landscape irrigation can be a significant chunk of your water bill during the summer. By switching from a grass lawn to a low water-use landscape design with drought-tolerant native plants, you can save both water and money! City of Flagstaff water metered customers can contact the Water Conservation office at (928) 213-2116 to schedule a FREE pre-removal (i.e. when your grass lawn is still intact) inspection of their site to find out if they may qualify for a low water landscape rebate. No rebate will be issued to sites that have already allowed their grass to die or if the grass has already been removed.

Low Water Landscape Rebate Policies:

  • Rebate amount is $0.25/square foot of grass lawn removed
  • Grass lawn must be replaced with approved low-water use plants (list coming soon!)
  • The home-owner must install at least 50% native plants*
  • No spray irrigation is allowed in the eligible area
  • No ponds or fountains may be on site
  • The site must demonstrate water savings to qualify (i.e. you need to calculate the water use of the newly installed plants)
  • Applicant must agree to have a water check up for indoor water use
* Native plants, which are naturally drought-resistant and low-water are a better option than just gravel. Native plants decrease the heat island effect, absorb stormwater run-off, and provide beneficial habitat for pollinators and migrating insects.
