The High-Efficiency Toilet (HET) rebate program is available to Commercial and Multi-Family Tucson Water customers whose building was constructed prior to 1991, or if located in the County, built prior to 1994. The program will rebate the replacement of toilets that use 3.5 gallons per flush or more with HET models that use 1.28 gallons or less per flush.
Tank-type HETs must have an effective flush volume of 1.28 gallons or less as certified by EPA's WaterSense Program.
Flushometer valve/bowl combination HETs must have an effective flush volume of 1.28 gallons or less as rated by MaP testing.
Tucson Water customers can receive $75 per tank-type toilet and $150 per flushometer valve/bowl combination. Applicants must submit a W-9 form form for rebates $600 or more, which are subject to tax, and will be issued a 1099-MISC for miscellaneous income. The W-9 form requires submitting your social security or tax identification number.
