Commercial Rebates*
To help businesses and multi-family dwellings reduce their water consumption, we offer various rebates for outdoor and indoor water-savings.
The commercial irrigation efficiency project rebate program encourages custom irrigation system enhancements designed to save water and money. This rebate program is for non-residential Thornton water customers (for example, HOAs, schools, churches, businesses, and multi-family properties). The rebate is a 50% match, up to $10,000, subject to budget availability.
Project examples could include the installation of weather-based controllers, rain sensors, hydrometers, and master valves, as well as the replacement of inefficient irrigation system components. If you have a water-saving project in mind and would like to see if it qualifies, and if funding is available, contact Water Resources at 720-977-6600 or email Water@ThorntonWater.com.

Rebates for tank-type toilets are up to $75, while flushometers and urinals are eligible for rebates of up to $150. If you are replacing more than 10 toilets, you must contact us to detail the replacement project and obtain written pre-approval. Replacement toilets must be WaterSense certified. Toilets with a 1.6-gallon-per-flush rating or that are dual-flush do not qualify. For replacement of installed toilets only, not for new construction. Contact Water Resources at 720-977-6600 or email Water@ThorntonWater.com with questions.
