Rebate for WaterSense Labeled Toilets Makes Cents

The single best thing you can do to improve toilet efficiency is to replace an old inefficient toilet with a newer water-efficient model.

Toilets are typically the largest indoor water user. While older toilets use between 3.5 and 7 gallons per flush, new high-efficiency toilets and dual flush toilets use 1.3 or less.

The Portland Water Bureau is now offering a toilet rebate for WaterSense® labeled toilets.

Water Bureau customers can apply for the $50 rebate by replacing a toilet that uses 1.6 gallons per flush or more with a new WaterSense® toilet. To earn the WaterSense® label, toilets must use 20 percent less water than the current federal standard and meet rigorous performance criteria.

Rebates are available on a first-come, first-served basis.

How to Apply

  • Step 1: Select, purchase, and install your new WaterSense® labeled toilet.
  • Step 2: Make sure to save your receipt.
  • Step 3: Recycle your old toilet and save the receipt. The old toilet must be recycled at an approved recycling center.
  • Step 4: Complete and sign the Residential Rebate Application form. Attach a copy of the sales receipt and a proof of recycling of old toilet.

Approximately four to six weeks after receiving your completed application and verifying eligibility, the Water Bureau will send a rebate check.
