Residential customers may apply for a rebate of up to $75 when replacing an existing fixture with a qualifying High Efficiency Toilet (also known as an HET). HETs use no more than 1.28 gallons per flush (gpf). This is 20% less water than the current standard 1.6 gpf for toilets. Note that 1.6 gallon toilets do not qualify for rebates.

Older toilets (those made before 1992) generally use between 3 and 5 gallons of water per flush, and some use even more. HETs save more than 60% versus older toilets. For a family of four, installation of HETs could mean water savings of more than 50 gallons per day or 20,000 gallons a year.
