Toilet Rebate Program

Program Overview


To help residents save water and lower their water bills, we have a WaterSense High Efficiency Toilet (HET) Rebate Program available to qualified customers. Any toilet purchased must be a High Efficiency Toilet (HETs use an average of 1.28 gallons per flush or less) and must be on the Environmental Protection Agency’s (EPA) WaterSense list.

Any toilet which meets the criteria and was purchased and installed within the last twelve (12) months will be eligible for the rebate (PDF). In most cases, rebates will be applied as credits to customers' water bills. Complete details are on page 2 of the WaterSense HET Rebate Application.


Residential Customers

Single family and multi-family* residential customers can receive a rebate credit for putting WaterSense HET toilets in place of all existing 1.6 gallons or more per flush toilets. The amount of the rebate will be for the cost of the toilet only, up to $100 per toilet. To apply for the rebate/credit, submit all of the following:
  • The original, dated sales receipt or invoice. If submitting an invoice from a plumber, the invoice must be itemized to include the model number and price of each toilet, separate from installation cost. 
  • A copy of your most recent water bill.
  • A completed Durham Department of Water Management WaterSense Toilet Rebate Application (PDF).
Please mail all materials to the Department of Water Management Durham HET Rebate Program (see application (PDF) for address). Do not mail your bill payment with your rebate materials.

*Multi-family residential customers are limited to a maximum of 75 rebates per property and are subject to mandatory random verification of installations..
