The first step to conserving water and saving money on water and wastewater bills is making sure you have efficient plumbing fixtures. Replacing older, high water use toilets with high-efficiency models is one of the best ways to save water. 

High-Efficiency Toilets 
High-Efficiency Toilets (HETs) are defined as fixtures that flush at 20 percent below the 1.6 gallons per flush (gpf) U.S. maximum or less, equating to a maximum of 1.28 gpf. The HET category includes dual-flush toilets which have two separate flush volume options. As of January 2014, California state law defines high-efficiency toilets as the current standard. We offer rebates for only 1.28 gpf and lower models on our approved list and no longer rebates 1.6 gpf toilets. 


San Francisco commercial businesses are eligible for cash rebates of up to $125 per tank style toilet and up to $500 per flushometer valve toilet when they replace their high-flow toilets (3.5 gpf or more) with High-Efficiency Toilet (HET) models that are 1.28 gpf or less. We no longer provide rebates for 1.6 gpf toilets.

For complete program rules, please download the Commercial HET Rebate Package below and review the application before purchasing.

Limited Funding Available

Funding is limited and rebates are available on a first come, first served basis. Toilets must be installed and rebate applications must be postmarked within 60 days of the purchase date.
