High-Efficiency Toilet (HET) Rebate


Rebate Changes Coming July 1st!

Tucson Water is updating rebate program policies to maximize water savings and encourage customers to consider additional ways to save water.

Toilet Rebate Changes: Only Premium high-efficiency toilets flushing 1.1-gallons per flush or less are eligible for a $100 rebate for residential properties (including multifamily) built before 2011. Single-family customers, maximum 2 Premium HETs per property. Multifamily maximum, 2 Premium HETs per unit.

Rebate Policy changes will go into effect July 1, 2022. Any fixtures purchased on or after this date will be subject to the updated policies. For more information, click here.


Note: Due to fluctuations in staffing during this time, rebates and credits may take up to 12 weeks to process. Please be patient.

Replacing older 3.5 gallons-per-flush or greater toilets with high-efficiency models is a cost-effective way to conserve water and save money.

Rebate is $75 per toilet replaced (maximum $150 for two toilets; the rebate is issued as a credit on your utility bill)
