Rebates for High Efficiency Toilets (HETs)

Millbrae water customers are eligible for toilet rebates when they replace an existing toilet with new efficient models. Starting on July 1, 2017, only the MaP Premium HET toilets that flush at 1.06 gallons or less will be available with a rebate amount of up to $100.


The Standard EPA WaterSense Labeled HET toilets that flush at 1.28 gallons with a rebate amount of up to $75 are no eligible for a rebate. 

Please review the application for eligibility and details.

  • 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.
