Conservation Rebates



The City of Round Rock offers rebates to direct City water customers that are taking steps to conserve water. Thank you for doing your part to help protect the City’s water supply!
  • Rebates are available to direct City of Round Rock water customers (MUD customers are not eligible).

Residential and Commercial Programs:

Clothes Washer Rebate
For the purchase of high efficiency clothes washer(s).

Clothes washers account for 22% of water use inside our homes. New front-loading efficient washers use 15-40% less water, depending on age of previous washer. Energy Star labeled washers use 20% less energy, 35% less water, and have larger wash tubs, which means fewer loads.

*NEW* Lawn Aeration and Compost Rebate
Help grow stronger tuft and hold water on your yard.  This new rebate is for having your yard aerated AND adding a layer of compost to the yard.  Core aeration and compost promote deep root growth and reduce water runoff.
  • Please note: since this is a new program, no applications will be accepted for services completed before the program start date of July 1, 2019.  We appreciate you having the work completed, and your yard will love it, but we cannot give a rebate for services provided before July 1. 
  • Available for all property types.
  • Both services must be included, not just one or the other.
  • Rebate amount is up to $100 per residential account, $300 per commercial account.
  • For full details see the Lawn Aeration and Compost Rebate.
Irrigation System Upgrade Rebate
For specific upgrades or newly installed efficiency components to existing irrigation systems.
  • Available to customers with existing, working, irrigation systems.
  • Applicants MUST have a working rain sensor/shut-off device on-site.
  • Rebate is 75% of cost of device(s), up to $500 per residential account or $1,000 per commercial account.
  • For full details see Irrigation System Upgrade.

Upgrading irrigation systems to be more efficient reduces water use and water waste while improving the health of landscapes.

Irrigation System Check-Up Rebate
For an irrigation system check-up or tune-up by a Licensed Irrigator.
  • Available to all property types.
  • Rebate is 75% of cost of service, up to $150.
  • For full details see Irrigation Check-up Rebate.

Outdoor watering accounts for up to 60% of the City’s total water use in the summer! By making irrigation systems more efficient, we can reduce water use, water waste, and improve the health of landscapes.

Rainwater Collection Rebate
For the purchase and installation of rainwater collection barrels.
  • Barrel must be made specifically to hold liquid. Home-made barrels (i.e. converted trash cans or drums) will not qualify.
  • Rebate is for a portion of the cost of the water storage container, pad material, pump, pipes, and gutters.
  • Rebate is up to $600 per water account, per year.
  • For full details see Rainwater Collection Rebate.

Rainwater can be used for non-potable purposes such as watering plants and landscapes. Rainwater is better for plants than treated potable water, due to higher nitrogen levels – reduces soil erosion on the property and helps conserve our drinking water supply.

Commercial ONLY Programs:

Indoor Fixture Rebate Program
For the purchase of WaterSense Certified showerheads, faucets, faucet aerators and/or pre-rinse spray valves.
  • Available to commercial, industrial, governmental, and apartment properties.
  • Rebate is up to $800 per water account.
  • For full details see Indoor Fixture Rebate.
Toilet and Urinal Rebate
For the purchase of WaterSense Certified toilets and/or flush urinals.
  • Available to non-residential properties built prior to January 1, 2006.
  • Rebate is 50% of the cost of the fixture, up to $100 per fixture.
  • For full details see the Commercial Toilet & Urinal Rebate.
Toilets are the largest water-using fixture inside a property; by replacing old toilets with efficient, 1.28 gallons per flush, toilets, you can save up to 4,000 gallons of water per toilet, per year! You can save on wastewater charges too!
