The City of Tempe is offering a Toilet Rebate to residents who purchase and install a high-efficiency toilet (flushing 1.28 gallons per flush or less). Toilets use about 24% of residential water use, the largest source of water use inside the home. By investing in an efficient toilet, you will save water every time you flush the toilet. How much you save depends on the age of your existing toilet. Toilets sold prior to 1994 used 3.5 to 5.0 gallons per flush.

Please note, only two (2) toilets per house are applicable for the rebate. If you are a new to the home or unsure of your eligibility, please contact Water Conservation by calling (480) 350-8351 or by email prior to submitting the rebate form to determine if your home qualifies.


Tempe is offering a rebate of 50% (up to $75) of the purchase price of each high-efficiency toilet (up to 2 per home). After installation, you also have the potential to save 50 gallons of water per day.
