Rebates for High Efficiency Toilets (HETs)

Millbrae water customers are eligible for toilet rebates when they replace an existing toilet with new efficient models. There are two levels of rebates for high efficiency toilets.

  1. The MaP Premium HET toilets flush at 1.06 gallons or less with a rebate amount of up to $125.
  2. The Standard EPA WaterSense Labeled HET toilets flush at 1.28 gallons with a rebate amount of up to $75.

Please review the application for eligibility and details.

What are HETs?

The standard WaterSense labeled HETs are water-efficient toilets that are designed to use 1.28 GPF or less and meet a minimum MaP threshold of 350 grams of waste removed from the toilet fixture in a single flush.

  • MaP Premium HETs are the most efficient toilets available on the market. In addition to meeting the rigorous performance standards of the WaterSense labeled toilets, MaP Premium toilets must use 1.06 gallons per flush or less and meet a minimum MaP threshold of 600 grams of waste removed from the toilet in a single flush. MaP stands for the Maximum Performance scale that rates toilet efficiency and flush performance and gives detailed information on individual toilet characteristics.
